3.When configured as a conventional thermostat, by default this thermostat does not turn the fan on with a call for heat. If the furnace requires the thermostat to turn the fan on with a call for heat, configure the “System Mode” to “Fan On With Heat” under “System Options”.
4.A conventional thermostat can be configured for automatic changeover heat/cool, manual changeover heat/cool, heat only, or cool only thermostat.
5.Refer to the “Configuration” steps under the wiring diagram for the respective HVAC system type.
6.If the thermostat or HVAC system does not perform as stated in the “Power Up” steps under the wiring diagram for the respective HVAC system, recheck all wiring - See Troubleshooting Tips.
7.For HVAC systems with separate heating and cooling transformers, the metal jumper between Terminal 1 (RC) and Terminal 2 (RH) on the left terminal strip must be removed – See Figure 5.
