Installation

Remote Input Wiring

The thermostat is equipped with a remote input which allows connection of a telephone controller or a home automation system to switch from normal operating mode to Frost Protection mode, or vice versa.
NOTE: For details on wiring and operating the telephone controller or home automation system, refer to the instruction manual of particular models.

Remote Input Wiring

Installing the Batteries

When you first install the batteries, the unit runs a sequence of tests which lasts approximately 5 seconds.
The thermostat will display an icon indicating that the batteries must be replaced. This icon will be displayed for 60 days; after this delay, the thermostat will shut down the heating unit. Once batteries have been replaced, you will have to reprogram the clock & day settings; all other programming is stored in a protected memory.

On/Off Button
The thermostat is equipped with an On/Off button making it possible to put the thermostat in sleep mode when its use is not required (e.g. summer). This will not affect the clock or programming.

Temporary Bypass
When the thermostat is in Auto or Frost Protection mode, you can bypass the mode for two (2) hours. The thermostat will maintain the temperature bypass for two (2) hours, then return to previous operating mode. Set the temperature using these buttons. The icon corresponding to the bypassed mode will flash to indicate the bypass.

Pre-programmed Schedule

The thermostat is pre-programmed with the following schedule:
