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.
