I've been working on a large upstairs project for about a year. Yesterday I opened the valves for the hot & cold water to the bathroom - quite a good feeling. All of my plumbing is complete for the hydronic baseboard heating right to the boiler. As soon as I get the flow valve wired I'm ready to throw the final lever.
My existing setup was 3 Taco 571-2 valves (two for heat zones and one for domestic hot water). I have added a 4th Taco 571-2 flow valve for the upstairs zone. All four valves are next to one another. I am using a Honeywell RTH4300B thermostat for both the heat and a/c in this zone. The a/c is using four of the terminals on the thermostat.
There are three terminals on the flow valve. From what I can determine from the instructions, terminal 1 and 3 get connected to the thermostat and terminal 2 is connected to the transformer. There appears to be a 4th wire from the transformer that jumps across terminal 3 as well. I assume I can just jump the #2 & #3 terminals from the flow valve next to this new valve.
So I think the white wire gets connected to the W on the thermostat and runs to terminal #1 on the flow valve and the Red wire gets connected to the R on the thermostat and then goes to terminal 3 on the valve. Do I simply jump terminals 2 & 3 from the neighboring valve?
I'm sure this is simple...but I just want to get it right.
