Single-Stage Conventional
Configuration
The EER56000 is factory configured as a single-stage conventional heat/cool thermostat. In the factory
configuration, the 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 “System Options.”
