Hot water heating system area pipe installation manual. This is our index to manual zone valves, sorted alphabetically by manufacturer name.

Installation & Technician Guides To Common Heating Controls, Free Downloadable Heating Controller Manuals

We include basic zone valve wiring instructions. For detailed zone valve wiring, select the manufacturer from our list and then the instruction manual for your specific zone valve.

This series of articles describes how to wire zone heating pipes. We include wiring diagrams and installation instructions for most models of zone valves and multizone controllers, and we describe special wiring problems that can occur when you mix different types, brands, or models of heating zone valves on the same hydronic heating system (hot water heater). . .

We also provide an index of ARTICLES for this topic, or you can try the SEARCH BOX at the top or bottom of the page as a quick way to find the information you need.

Controlling Zone Circulator On Radiant Loops That Also Have Zone Valves? — Heating Help: The Wall

To control up to eight heating zones, you can wire several standard switch relays together as shown in this TACO wiring diagram. This picture is from the TACO SR503-4 Relay Instruction Sheet linked above.

A few years ago I converted about 1/4-1/3 or my house to hydronic radiant floor heat that runs in the same area as the stove. The guy who sweated the tubes and the outside area never got back to contact the area manager.

Someone else went out to get it the other day. I have a TACO SR502 2 zone controller and this person bought a Honeywell L6006C 1018 aquastat controller.

I talked to techs @ TACO and WeilMcClain who both said I can run my floor heat separate from the BB units.

Absolutely, if connected properly, you can take a loop of heat baseboard hot water and subdivide it, giving each subloop its own thermostat and zone control valve.

Wired correctly, the individual thermostat requires heat, the zone valve opens, when the valve is fully open, a limit switch in the valve connects a second pair of wires that turns the circulation pump back to the boiler.

On most American systems, the circulator runs water through the open zone loops and a basic controller in the boiler, which controls the water temperature, actually turning the boiler on or off as needed to heat the water.

In addition to your control, Honeywell’s L6006C 1010, Honeywell’s L8124A, C and 8151A triple aquastats are similar in function, often used to control area valves.

Where you can run into problems is an installation that has a mixture of different brands of area pipes. In this case, the wiring instructions for one company may differ from the other.

When I encountered this problem years ago, I connected a Honeywell zone valve to a system that previously used Flair zone valves. I called my heating supplier who had Dave Ferris (now retired) on deck to answer questions about wiring.

The answer was trivial once Dave said – Hook the red wire to the “x” terminal and the yellow to “y” etc.

My ugly rough sketch above on this space needs a clean redraw, but there I show how we successfully wired a mixed mark area pipe configuration. I had two Honeywell zone valves and one White Rogers zone valve.

Without Dave, the next best thing is to look carefully at the instructions that came with the zone taps, and at the wiring diagrams for connection instructions; if you are still confused, the manufacturer will know how to contact.

Honeywell zone valves are NOT compatible with Flair and White Rogers unless you carefully follow the wiring details.

I gave an example above, but you may need to review the wiring with your area valve manufacturers.

Zone-A-Troll valves must not be wired into the same circuit as zone valves of another make or manufacturer

The thermostat wiring on the main control (main) will show about 20 volts at the thermostat relay transformer on the board inside the main control.

We see 24-volts in the zone controllers and transformers, but there is no voltage on the zone valve limit switch wire that goes to the TT terminal of the thermostat on the main or basic control.

Usually a single thermostat controls a heating zone and is connected to a zone valve. But since the thermostat is basically an off switch, we have indeed discussed with the readers the successful combination of more than one zone valve changed by the same thermostat.

Attention: to avoid overloading the TT or its power or circuit, check the wiring instructions valve area. To switch multiple zone valves with a single thermostat, you may need to get the thermostat controller, a switching relay that in turn switches the multiple zone bundles.

A typical switch relay such as the Taco SR502 – 506 can switch 4 or more zone taps.

We teach to completely remove the zone valve motor and electrical parts when sweating the zone valve in the heating system piping, but even so, overheating can damage the zone valve’s moving parts or o-ring seals.

Honeywell cautions against using brazing agents when welding zone valves due to the higher temperatures required with brazing agents.

From Flair Manufacturing’s original installation instructions for the Flair Zone-A-Trol, we have included the following wiring details. The Flair Zone-A-Trol valves in the company’s wiring diagram are usually shown wired in parallel.

On installations where it is impractical to wire from valve to valve as in the diagram, a separate 3-wire conductor may be run from terminals 1, 2, 3 of each zone valve to a convenient connection point.

By observing and respecting the color codes, the conductors can be soldered or soldered together from the terminals corresponding to the numbers of each zone valve and a single conductor from this load can be directed to the appropriate power and control terminals shown in the diagram in electrical wiring. .

When connecting wires to terminals in the zone valve and on the thermostat or any other control, do not allow the stripped end of the wire to touch or short any other wire or terminal.

See this image for the complete and detailed wiring diagram for the FLAIR 2-WIRE ZONE-A-TROL faucet. [image] An example of this page is shown just below.

On the left, the thermostat wiring diagram shows the use of the Flair APOV2 wall thermostat in a typical 2-wire application to control a heater.

In this application, the thermostat acts as an SPST (single pole single throw) switch to turn heat on or off, often using a zone valve.

When used to operate a zone valve, the thermostat wires are connected to the terminals of the zone valve, not to the main heating control of the boiler.

On the left is the thermostat wiring diagram showing a typical use of the Flair APOV2 wall thermostat in a 3-wire application to control a heater.

In this application the thermostat acts as a single pole double throw (SPDT) switch to control heating and cooling or in some applications a zone valve.

I’m also confused but your diagnostic steps so far are helpful; something is obviously power flow – either just in the thermostat or in the thermostat and the heating itself or in a circulator or circulator relay.

How To Replace Taco Zone Valve Head

The cause of the power drop can be intentional: a timer or saving, or a bad connection or control board (can be affected by temperature fluctuations).

Force the zone valve open and then get heat telling me the circulator is running but the zone valve is not open.

This condition means that hot water cannot circulate from the boiler to the area and this in turn will mean that the boiler sees the call for heat, switches on, heats up, but then reaches its LIMIT and change.

Hello, I have a problem with my heating and I cannot diagnose what the source of the problem could be. I have 2 zone (2 normally closed Schneider zone valves) water boilers and 2 AHUs (floor and attic).

Taco Zvc404 4 4 Zone Valve Control Use And Care Manual

Zone 2 heat works perfectly fine during the day, I checked the Rh and W1 wires with a voltmeter, I got a reading of 28V. When I use the ecobee app next to the water heater and call for heat, I see the zone valve open and hot water starts circulating. Works exactly as it should.

Something that I can not explain happens at 22:00, Rh and W1 wire reading is 0, when I call for the heat valve area does not respond. I changed the zone valve with ecobee, it did not help, exactly the same problem.

In the morning around 09:00 the power of Rh and W1 is back on and everything is working well. When I use the manual ON lever on the valve overnight, the boiler fires up and works fine. What do you think could be the problem and how can I solve it? Thank you!
