I'd have to really see your system.
ReplyDeleteI don't know anything about that AUBE relay--though it does say it has a built in 24VDC transformer, so you don't need a separate transformer.
I leave it up to you to make sure that that AUBE relay is rated for your load, and that your new thermostat is rated for 24V. Might need one for the heat side, and one for the cool side.
Typically a line voltage thermostat controls electric baseboard heat. FWIW. Do your baseboard heaters have a knob on them?
Baseboard your only heat, and then AC is forced air?
I understand you want to replace a line voltage thermostat with a low voltage programmable thermostat. I see this as a simple relay hook. The new low voltage thermostat would be used to switch a relay that would switch the line voltage for the baseboard heaters. I can not think of the name of it just now but there is a company that makes a kit just for this. I have install 3 or 4 over the years. In your case the thermostat on wall now (the one in the picture) would be replaced by a relay box. The new low voltage thermostat would be placed beside it. A short wire would connect the two. The new low voltage thermostat would have it's own separate power supply. Google "baseboard heater relay kit"
ReplyDeleteEDIT=Here is once such set up http://www.fixmyownairconditioning.com/images/ACC0436-wiring.gif
Here is one with the unit mounted knob control being replaced by a relay. http://www.gntrains.com/CanalCar/Images/P02_0203_1758_0045a.jpg
