This is a new thermostat. Two wires (red and white for furnace) wires
check ok with voltmeter @26VAC. Cooling is only option - no heating
option on app or thermostat. Any ideas?
I returned the thermostat. Did not receive any specific advice. With
only a simple 2 wire connection (red and white for furnace only) and
with the AC voltage checking out, I assume it is a product issue. Gave
up.
