The installer surely had a reason for the "normally-open" approach. In that case if the circulator runs hot water will circulate. See AIR BLEED VALVE INSTALLATION
WHITE RODGERS 1311 ZONE VALVE INSTRUCTIONS [PDF], On 2021-05-18 by Jon Green - two wire thermostat vs White Rogers 1311-102 Zone-A-Flow valves. A typical design will include a thermostat on the water heater that will cause hot water from a physically separate heating boiler to circulate through the heating coil located in the bottom of the indirect-fired water heater. I have an overheated Taco zone control valve, that is always hot, even when the boiler is off and water temp in it is down to 100 degrees with cold pipes. IF the motor is hot and nearby pipes are cool then the motor itself is seized and perhaps electrically unsafe. About the "why" of requiring electrical energy to close the valve when the thermostat is satisfied, I'm embarrassed to pretend to second guess WR's engineers who certainly know more about it than you or I, but maybe the idea was to make an inexpensive zone valve that would close more-reliably than a spring-operated valve. B of motor switch opens (breaking auxiliary circuit), and side But I've not found that data available to the public. PLUMBING NOISE DIAGNOSIS & CURE

We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. Would it be better to have normally closed valves instead of the normally open ones? The contact arrangement is constructed so that when the shaft - HONEYWELL V8043D ZONE VALVE INSTRUCTIONS [PDF], Details on the risks of damage or component failure from dissolved oxygen in heating system water as well as suggestion on avoiding those hassles are now found. This contact provides a but at some convenient locations the installer joined several of those individual zones into one of two return lines - that's why you see just two hydronic heat (hot water) lines returning to the boiler. Our photo at left shows a Honeywell (TM) zone valve installation. calls for heat in a particular building area, the thermostat switch causes the zone valve to open, to permit hot water to flow through that zone. Thank you. Seems to be an unnecessary component in the system. position. Soon thereafter side A of motor

The thermostat is at the lowest setting but our oil in floor heating system still fires up here and there (we dont want the oil in floor on since we have electric heat pumps running). There's theory that the slightly lower temperatures give longer component life and that this location will reduce water hammer noise in the heating zones. Here is another pic of the system, any insight someone could provide on changing my zone valves and the steps I need to do to pull it off would be so appreciated! Is this a residential building? Also, can the zones valves be installed on the return side of the boiler instead of the supply side? by Trevor - how to replace Sparco PowerTrack zone actuators broken into pieces. I use the word "register" to refer to a warm air outlet - a furnace heating system - is your heat a water-to-air heating system? Can I just cut out the old actuators and install the new zone valves on my own? i have no idea the close water pressure test for the zone valve by the manufacturer. Watch out: for conditions that could contribute to zone valve failure. I have 3 separate zone valves in my home. thermostat calls for heat, the valve motor is energized and
motorised honeywell replacment honewell or something? So I can't imagine any way to install a zone valve without installing it somewhere on the hot water heat piping loop for the zone it's intended to control. (Fig. Probably one thermostats at a time. I have a four zone one circulator pump hot water system. What is the downside to installing a 4043 zone valve backwards? Continue readingat ZONE VALVE MANUALS & WIRING or select a topic from the closely-related articles below, or see the complete ARTICLE INDEX. If piping on the outlet side of the zone valve is hot then you can be pretty sure. hydronic systems. And over time a relief valve that leaks can also clog from mineral deposits and - to put it technically - crud on the valve seat. convectors, fan-coil units, etc. First let's get heat back: for those two zone valves: try putting the valve in the MANUAL OPEN position to see if that restores heat; that'll be diagnostic. For that work, the job probably goes faster and easier when done by a trained heating service tech or plumber who is familiar with zone valve replacement. Our recommended books about building & mechanical systems design, inspection, problem diagnosis, and repair, and about indoor environment and IAQ testing, diagnosis, and cleanup are at the. NO - Normally-Open, and use a current to close the valve breaks the holding contact.

You can obtain the installation guide and ask questions of Honeywell at 1 (877) 663 0316 TACO ZONE CONTROLS WIRING GUIDE - Daniel, Zone valves we are using are a Honeywell V8043D 5080 normally open (held open by spring pressure). If that's the problem you'll want to replace the zone valve head. I would look first for a loose electrical connection and second I would consider replacing the zone valve actuator or motor that may be sticking or failing. It uses a two-wire, 24-volt control circuit and requires a SPST thermostat.
honeywell motorized Andre said: It's common for the body of the zone valve to be hot as it's passing hot water for the heating system. permit more detailed control of heat distribution in a building. See if you can pin down the noise source precisely.
If you give us the zone valve brand and model we can research further. There are no special heating needs or requirements. @Anonymous, plumbingsupply.com sells replacement Sparco PowerTrack zone actuators from Honeywell. Could my circulator pump be bad although the other three zones are working? "Cut" pipe, I interpret conceptually, since physical "cutting" or sawing isn't necessarily required if instead there are threaded fittings that can be unscrewed. Try the search box just below, or if you prefer, post a question or comment in the Comments box below and we will respond promptly. Thanks for all of the information it will help us in making a decision. Jay I'm sure it needs to be replaced. I live in a condo and the zone valve was hot to the touch and made a humming sound - is this a problem? When changing the thermostat, there are some models that can be wired to operate either type of zone valve: normally closed or normally open. on AIR-BOUND HEATING SYSTEMS to see how to diagnose and repair the problem. Not for use with oxygenated water, thx, if I gently push on the valve the humming changes. Your advice would be appreciated. The instructions don't say why but from my reading and field experience I warn that if you hook up a heating zone valve backwards, depending on several other variables including zone valve brand and model and type as well as water velocity there may be trouble: To be fair, not all banging noises originate at a backwards zone valve. And about using a normally-open vs normally-closed zone valve: it depends on the application; for example some hot water applications require the valve to be normally open. You'll save significantly just by dropping the thermostat set temperature.
by Inspectapedia Com Moderator - how to install a zone valve. Why would anyone want a valve like that, instead of a spring or mechanism that just turns the valve automatically to the off position when the thermostat turns off? When thermostat is satisfied, the valve motor is again energized. thermostat is presently off and it is possible the building heat has just been turned on for fall -. In order to change out a White Rogers Spin on or Twist On Zone Valve do you have to turn off the water or can you simply take off and twist on the new one?
boiler) and a single circulator pump (usually located on the return end of the hot water piping close to the heating boiler). When the circulator pump is running you should be able to feel the heating pipe on the inlet and Outlet side of a zone valve go from being cool or cold to hot. 3. turns on the circulator pump once the valve is open A clogged relief valve means that the heating equipment is unsafe to operate, risking a BLEVE. If the valve is dripping from the valve assembly or motor it's shot and needs replacement.
heating valve central water zone system port boiler motorized banico motorised Is this a pretty easy fix for the homeowner? Here are other sources of banging noises in buildings: At WATER HAMMER NOISE DIAGNOSE & CURE we cite these other banging heating pipe sound sources.
But you could argue that in the event of loss of heat but not loss of power, you'd gain that advantage. The valves cannot be moved to return lines without a lot of work.
1361 zone rodgers hydronic Watch out: however, for wiring errors, short circuits, or a misbehaving low voltage transformer. @Jason, Quoting from the company's product data: The V8043 Motorized Zone Valve provides two-position All radiators have thermostatic valves to control the heat in individual rooms. It is possible to simply change the actuator heads from the D model to one of the other models - changing wiring and thermostats as appropriate, leaving the actual valve body installed. When a zone valve is dripping from the solder or sweat connections it may be possible to repair it - but that'll usually require draining water out of the zone piping first. NC - Normally-closed, and use a signal to open the valve (Search InspectApedia.com for AIR-BOUND HEATING SYSTEMS to see how we get the air out completely) Dennis, I don't know.
But a humming sound may mean that the valve's motor is jamming (needs replacement) OR that a nearby low voltage transformer is humming and will need replacement soon.
geothermal 556g heating globalindustrial I don't like leaving it like that, so I put it there at night when the house gets cold, put it back to normal during the day. Reader should make sure they have at least a 75VA transformer for the valves - 60VA for full load plus 20% headroom. And this is not just an instantaneous short either - once those valves start going, they keep going as long as necessary. More diagnostic suggestions are at HEATING SYSTEM NOISE DIAGNOSIS https://inspectapedia.com/heat/Heating_Noise_Diagnosis.php, I have gas fired boiler laars mini therm jvs model and when one zone calls for hest boiler makes sound like plane passing by over the house but when two zones are calling for heat boiler runs fine snd the noise goes away. - one problem zone valve opens when I adjust the thermostat but the hot water only flows to the valve, If you're confident that the valve is opening then I suspect that zone is are bound. But if the zone valve problem is not the motor but the actual valve in the valve body - the parts that rotate to either allow or not allow hot heating water to flow through the piping, then what's needed is to cut-out or de-solder the old valve and put in a new one; that in turn also will require cooling down the heating system and draining the zone, the re-filling the zone after the repair, and then purging air from the system after that. This excerpt describes the operation of the White Rodgers 1311
It pays to read the specs.
motorised honeywell 22mm Good practice locates the zone controls and circulators on the return side of the hydronic heating loop. what can cause long delays in my hot water heating system actually having heat coming out of the registers? makes with holding contact providing a holding circuit. On 2022-03-01 by Inspectapedia Com Moderator. Head has been removed and valve now moves very freely using very little finger force.

InspectAPedia tolerates no conflicts of interest. I have no need for heat at the moment just possibly overnight - I am on the third floor - The motor stops with If the zones do NOT heat any rooms with plumbing you may be ok. - re-fill the heating system (assuming it's a water-only system) Typically the zone motor or actuator, (properly, the "zone motor assembly") including the White Rodgers models can be removed without interfering with piping A separate loop of piping conducts water from a nearby heating boiler, through the coil in the bottom of the indirect fired water heater tank (thus transferring heat to water in the water heater tank), and back to the heating boiler.
valve honeywell zone motorised 22mm port 1056 chat Zone valves on hot water heating systems: How do I choose & install a zone valve, how do I wire up a zone valve, and how do I troubleshoot, repair or replace a zone valve? The Good installation details install a zone valve on the return side of the heating piping loop where it will be exposed to lower and thus less stressful temperatures. This seems to have stopped working as the radiators were cold even with the Thermostatic Valves fully open. I have a zone valve dripping and when the thermostat turns on the zone valve spins and won't stop on open. When room temperature is reached the thermostat applies power to the valve and it closes, cutting off fluid flow.

Zone valves and Taco circulator pumps are, most-basically, associated with hot water heat delivered through radiators or baseboards or convectors. but if it's the valve itself I'd expect to turn off water and remove pressure from the zone. by use of zone valves (one per heating zone or area or "loop" of heating piping) which in turn are connected to individual thermostats. Checking the wiring (5 wire) against a wiring diagram the orange wire goes to a connecting block but no further. Reply: Norby, For other readers, the installation instructions and wiring diagrams for this zone valve are at
what is the hot water pressure for heating system normally? I've seen more Honeywell than Taco zone valves installed, but I have no actual zone valve failure rate data that demonstrates one BRAND is "better" than the other. Indeed when your boiler (hot water heating system or "hydronic heating boiler") is also used to make domestic hot water (for washing and bathing) the boiler will run form time to time to keep its temperature high enough to produce domestic hot water.
But first check for a bad check valve on that zone loop: hot water could be circulating even when the zone motor is off.
honeywell valve zone motorised 22mm port 1056 heating Heating System Zone Valve Failure Rates, Failure Data, Honeywell vs Taco It's likely that both Taco and Honeywell have failure data for their products based on their own research, on field reports, or both.
