Make the appropriate connections to the thermostat as per diagram 
below. The wires are non-polarized so either wire can be connected 
to either terminal.

Slide thermostat switch to 

 position. The thermostat normally displays 

the actual ambient temperature.

To view the setpoint temperature, press the 

 or 

 button once. The 

 icon appears and the thermostat displays the setpoint temperature. 

To change the setpoint, press the 

 or 

 button to raise or lower the 

temperature until the desired setpoint is reached.

To turn the backlight on, press the 

 button, or the 

 or

Install screw to secure cover.

Align and affi x the base to the electrical junction box or the optional 
adapter plate using two 6-32 pan head screws.

The thermostat displays the percentage of power usage (in "PC" mode 
only) required to maintain the desired temperature. For example:

 100% power usage

 70% power usage

 30% power usage

previous thermostat.

**  Proportional Control allows the thermostat to modulate depending 

on power usage.

***Adjusts your thermostat anticipation based on the room and base-

board heater size, e.g., in a room with a 3500 W baseboard heater, 
set your thermostat anticipation to AL. 

The thermostat will save the setpoint temperature and installer confi gu-

Most heating elements have a protection device that activates when 
overheated. It is possible that if the device is worn out, it becomes 
more sensitive. This device has a chance of being activated when 
the heating element is on for a long period of time. When the thermal 
protection is activated, the electrical power ceases to supply the 
thermostat, and its display is turned off for a few minutes. The same 
phenomenon exists with a mechanical thermostat but nothing could 
indicate it. A thermal protection that opens too often can cause the 
thermostat to poorly regulate temperature and should be replaced by 
an electrician or the heating element manufacturer.
