1Place the switch in Standby to cut power to the heater when not in use (e.g., in the sum- mer). This will not affect the time and temperature settings.

2If your thermostat is installed on a power base equipped with a ground fault protection, to reset the ground fault protection, switch the thermostat to Standby and back to On.

3The thermostat displays the percentage of heating time required to maintain the desired

temperature. For example, is displayed when heating is activated 40 percent of the time.

oConfiguration

Some thermostat configurations can be modified via switches on the back of the faceplate (control module).

Default (factory) settings are inside the gray cells.

#	Configurations	UP	DN
1	Display format	°F / 12 h	°C / 24 h
2	Early Start a	Enable	Disable
3	Temperature control mode b	F	AF

a.Early Start can be used in Automatic mode only. When this function is enabled, the thermostat calculates the optimal time to start heating in order to obtain the desired temperature by the set time. The thermostat re-assesses the start time daily based on the previous day’s results.

b.To select the F mode, place the switch in the F position. To select the AF mode, place the switch in the AF position and ensure that the remote temperature sensor is connected to the thermostat. To select the A mode, place the switch in the AF position and ensure that the remote temperature sensor is NOT connected to the thermostat.
