Wiring a Honeywell V8043E to a Taco System. (Wires are identified with letters to correspond with wires on Fig. 23.) Fig. 25. Wiring a Honeywell V8043F to a ...
12 - Typical 3-zone system. Use an AT87A Transformer to power up to five more zone valves. Fig. 11 - Wiring diagram for V4244 and V8244 with Aquastat®.
Mar 3, 2014 · The zone valve in question is a Honeywell V8043. It has a pair of red wires and a pair of yellows. There are two 40VA transformers installed (3 zones per).
Hello ... I recently had a 6 zone heating system installed. My problem is, the 6th zone, although installed, was not wired.
Sep 19, 2004 · The yellow wires (2) are the 24Volt power circuit. The V8043E1012 has leads attatched, but there are other models, V8043F1036, with just the ...
Anyone had the pleasure wiring one of these up? What a pain in the crack.
Five of these wires are the same as 22mm 2-port valve. Green/yellow is Earth, blue is Neutral, brown is Live (or Line) to the motor, grey and orange are connected to the end switch and form part of a separate circuit.
Electrically, the valve has 5 wires: Green/Yellow, Earth - connected to the metal body of the valve. Blue, Neutral - internally connected to the neutral side of the motor. White, Live in 1 - Activates the motor inside the valve to select either AB (both) or A (heating)
The redd leads go to the boiler control/relay thermostat terminals. 1 yellow lead goes to the transformer common the other to thermostat W. Thermostat R goes to the transformer hot.
It connects your thermostat to your air handler or furnace. The white wire connects to terminal W in most industry-standard thermostats. If your HVAC system has multiple heating stages, then you may find more than one white wire.
You will usually only see a red wire when an outlet is a 240-volt outlet or when a wall switch controls the outlet. In this case, when the switch is "on," the red wire will supply power to the outlet instead of the black wire. Like black electrical wires, red wires are also hot or live wires.
In standard North American wiring, green means ground. Most commonly, if you're talking about DC systems, red is positive and black is negative. In single-phase AC, black is live, white is neutral. In both systems, green means ground.
If you have a mid position valve - the one that makes a T junction, one pipe goes to the hot water cylinder (marked B on the zone valve), and the other to the central heating (A). The pipe marked AB comes from your boiler, so it should be hot.
The brown is a switched live to the motor and the grey is a permanent live to the micro-switch which then energises the orange wire to the boiler - which must only operate once the valve has been opened.
The extra white wire is another type of live: it acts as a signal or switch input for either the heating or hot water circuit, moves the motor round and turns the boiler or pump on. It's a little extra system safeguard so the boiler of pump don't run unnecessarily when there's nowhere for the water to flow to.
