Thermostat for specific zone valve
Cata
Member Posts: 1
Hello there
I am a newbie and I am looking for an analog simple thermostat suitable for a zone valve V8043D1197 or V8043D1205. The system I have is "heat only", with 24V AC (2 wires).
The second question: as the power is AC, matter how I will connect the terminals (R and Y)?
Many thanks in advance,
Catalin

The simplest and most reliable out there is the Honeywell T87K -- https://www.amazon.com/Honeywell-CT87K1004-Available-RoundHeat-Thermostat/dp/B000EANORW/ref=sr_1_1?crid=2C17ATEIMWA5L&dchild=1&keywords=t87+thermostat&qid=1634316852&sprefix=T87,aps,362&sr=8-1
No batteries. No fancy stuff. It just works... and goes on working.
As to hook up -- a thermostat like that is a simple switch, just activated by temperature. You need 24 VAC to power the zone valve, and all the thermostat does is turn the power to the valve on or off -- so any two wires will do. That said, you might just as well use a red one and a white one...Br. Jamie, osb
