Nest thermostat and current HVAC system
I need advice as to whether a nest gen 3 thermostat will work and have sufficient power to run off the TACO switching relay that I currently have. My current system which has a battery operated thermostat is highlighted in blue in the attachment. What I intend to do is run a c-wire from the TACO com on the board to the C terminal on the nest. Thanks in advance of your help.
