The time on the programmer must be correct. Some types have to be adjusted in spring and autumn at the changes between Greenwich Mean Time and British Summer Time. You may be able to temporarily adjust the heating programme, for example, ‘Override’, ‘Advance’ or ‘Boost’. These are explained in the manufacturer’s instructions. Programmable room thermostats need a free flow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric fires, televisions, wall or table lamps may prevent the thermostat from working properly. WHAT IS A PROGRAMMABLE ROOM THERMOSTAT?
3 This section shows you how to setup and run the thermostat in 3 simple steps: STEP 1: Installing the Batteries Note: Please follow the instructions in this section only if the thermostat screen is blank (no symbols or digits are displayed).

89 OPERATING THE CM907 Choosing the Operating Mode The thermostat can operate in three different modes: Automatic, Manual or Off. To set the operating mode move the slider switch to the desired position. The screen indicates which mode is currently active by displaying AUTO, MAN or OFF. • AUTO (automatic) mode Automatic mode sets the thermostat to follow the temperature program (default or personalised). Operating the thermostat in this mode is the best way to maintain a high level of temperature comfort whilst maximising your energy savings. • MAN (manual) mode Manual mode sets the thermostat to act as a simple thermostat with a fixed setpoint throughout the day. The setpoint can be adjusted from 5°C to 35°C by using the or buttons. The thermostat will continue to maintain this temperature until another operating mode or temperature is selected. • OFF mode Off mode sets the thermostat to control to a minimum temperature setting of 5°C (default) that acts as a frost protection measure for your home. This value can be adjusted by calling your installer. During Normal Operation • Temperature Enquiry In AUTO and MAN operating modes the thermostat will display the current room temperature, which is indicated by the text ‘ROOM TEMP’ displayed on the screen. To review the programmed ‘target’ temperature (the temperature which the thermostat is trying to maintain) press the button. This ‘target’ temperature value will be displayed flashing and the text ‘TARGET TEMP’ will be shown for 5 seconds before returning to the current room temperature value. In OFF operating mode the thermostat again displays the current room temperature, as above, but when the button is pressed the text ‘FROST TEMP’ is displayed indicating the set value to protect your home. To modify this value please contact your installer.
89 OPERATING THE CM907 • Temperature Override During normal operation (AUTO mode) the programmed temperature can be adjusted manually by pressing the or buttons. The ‘target‘ temperature will be displayed and flash for 5 seconds – during this time the or buttons can be used to modify the set value. Note: This temperature override is cancelled at the next programmed temperature change.
