Greetings.
Been meaning to post this question here for awhile. I swear I did, but ... maybe I dreamed it.
Does anyone know of any thermostats that are rated for 60-70 VAC? It's a water cooled heat pump system and it's got some solenoid shut offs on the water pipes. The amperage draw on the thermostat is going to burn it out for sure. Most T-stats I've encountered are rated for 20-30 VAC.
That sounds pretty weird. I would use a 24v transformer and use a normal thermostat with a relay to open/close contacts on the 60/70 side.
Electric baseboard thermostats are all rated for 220VAC. A mechanical one would work with 70 VAC, but the voltage would be too low for an electronic one.
