Pre-comfort Recovery

This thermostat is equipped with a ‘Pre-comfort Recovery’ system that will activate the heating system in advance of the actual set program time so that the room will be at the desired temperature at the start of the program time.

It is normal for the system to be activated earlier than the actual set program time (up to one hour). The Pre-comfort Recovery can be disabled if desired. If pre-comfort recovery is turned off (rE:0), heating will only be initiated at the exact start time the program period.

Heat Cycle Rate

Cycle rate determines the heating on/off time cycles and the level of proportional power required to operate the heater. (To have the heater operate at full power all the time, select Cr 0 to disable heat cycling.) The cycle rate is based on the type of heating system and the power load required to operate the device. The higher the load (size of baseboard or radiant heater) the greater the heat generated.

Cr 0 is continuous operation (no cycling), with a variance of +/- 0.3°C (+/- 0.6°F). The heating unit will operate at full power and the arrow bar icon will appear full. This function is for users who do not want their electric heating devices to turn on and off frequently.

Cr 1 is a 20 second cycle rate with proportional heating. This means the heating will be turned on and off once every 20 seconds to provide a stable room temperature. This cycle rate allows a proportion level of power to the heating device. This is indicated on the thermostat display by the arrow bar icon which will be partially filled, indicating the amount of power going to the heater. This setting is recommended for standard electric heating devices, without fans, and will provide the most energy efficient heating and a stable temperature.

Cr 2 is a 240 second span. This means the heating will be turned on and off once every 240 seconds. This is the recommended setting for fan assisted heaters and radiant floors and ceilings.

High-Limit Function

The high-limit function is a security feature which allows you to select the maximum temperature limit of the thermostat. When this function is ON the thermostat will not allow heating settings to exceed this temperature limit.

To enable the high-limit setting feature:

① Press "UP" or "DOWN" to scroll to the desired high limit temperature
(this temperature will display in the program temperature pane on the LCD screen)
② Press the USAGE/TIME button and OPTION/COPY button for 3 seconds (both at the same time)
(the LOCK symbol will appear to confirm that the high-limit feature is ON)

To disable the high-limit setting feature:

① Press and hold the (R) RESET button (located under faceplate / press with a narrow blunt object) (The lock symbol will begin flashing)

② Press the USAGE/TIME button and OPTION/COPY button for 3 seconds (both at the same time)

(When the LOCK symbol disappears this indicates that the high-limit feature is OFF)

Note: When the high-limit function is ON all existing programs will be changed. If any temperature settings are above the high-limit they will be reduced to the high-limit setting. The temporary override maximum temperature setting will also be limited.
