Thermostat
Install the room thermostat according to the instructions
provided with the thermostat. See gure 29 for thermostat
designations. If the furnace is being matched with a heat
pump, refer to the FM21 installation instruction or appro-
priate dual fuel thermostat instructions.
Indoor Blower Speeds

blower will run continuously on the fan speed when
there is no cooling or heating demand.
2 - When the EL180UHE is running in the heating
mode, the indoor blower will run on the heating
speed.
3 - When there is a cooling demand, the indoor blower
will run on the cooling speed.
