Ecobee3 lite and 2 stage furnace
Got a new 2 stage furnace. Previously had a single stage furnace connected via PEK to the Ecobee. Right now the furnace starts in first stage and then goes to the second stage of heating. Do I leave it like that? The thermostat has the "Fan control in heat mode - Ecobee thermostat".
Do I leave it as it is or any settings/connections to change?
appreciate any help.
