2.3 Proportional or ON/OFF heating control
This thermostat has been factory set to proportionally control electric
baseboards, radiant systems and convectors. Since proportional control uses a
fast commutation rate, it is not compatible with fan equipped systems (see
characteristics). Also, this control mode could occasionally create light flickering,
especially in rural area.
The ECONO mode has two (2) programs in which the
day, the time and the setpoint has to be programmed. For
instance, this operating mode can be used for a cottage
installation where the user goes only on weekends.
You can change the control mode to make it compatible with fan equipped
systems or to eliminate the light flickering.
Program 1: Friday 3:00 PM, 20 °C
Program 2: Friday 8:00 PM, 15 °C
To do so, maintain MIN button pressed down as RESET button is being pressed
on and released. Then release MIN button. Following this operation, the display
will show the fan indicator. To return to proportional control, repeat the same
The temperature will be maintained at 20 °C Friday from
:00 PM to 8:00 PM, and maintained at 15 °C the rest of
This gives you a comfortable temperature at your arrival
and if you are not going to your cottage for the weekend,
there will be only a minimal heating period.

set if power failure is more than six hours. The thermostat will return to the same
operation mode as set before the power failure.

500 WATTS OR LESS INSTALLATION
During the 30 minute period following the installation or a long power failure
more than 6 hours), the light intensity of the display decreases when a button is
pressed on while the thermostat is in the heat mode. This problem will disappear
when the accumulator for the memory backup will be charged.
