CONFIGURATION

• From the factory, the RC500-2EW is configured as a single stage conventional
heat/cool thermostat.
• In the default configuration, this thermostat does not turn the fan on with a call for
heat. If the furnace does not turn the fan on with a call for heat, the thermostat
must be configured to do so under "HVAC Settings".

connections.
2. Connect power to the transformer and system.
3. Attach the thermostat to the base, the display will show the current temperature
reading.
4. Press [FAN]. The fan icon should display in the lower left-hand corner of the
display and the system fan should come on.
