Devices Modes
Automatic Operation
During normal use, your Thermostat will follow the programmed schedule – indicated by the icon.
Manual Operation
The set temperature is followed permanently – indicated by the icon.
Temporary override
Press the or set the new desired temperature. The programmed schedule will resume at the next programmed setpoint.
Permanent override
Press the or buttons to adjust the set temperature. This temperature is set until manually changed again.
Standby mode (with frost protection)
Save energy by switching the heating off when not required – e.g., during warmer summer months, or when doors and windows are open for extended periods of time. If the temperature drops to 5°C, the heating will come on to prevent the heating pipes from freezing.
- Press to switch the heating off – the display will show OFF.
- Press again to switch the heating on – the display will show.

Optimization
Your Thermostat has optimization functions that aim to save energy while maintaining suitable comfort levels. The Thermostat displays during the optimization period if set. By default, optimization is disabled. See instructions in the installation guide on how to activate it.
- Optimum Start learns how long it takes your home to reach a set temperature and then turns the heating on a bit earlier to achieve that temperature at the programmed time.
- Optimum Stop saves energy by switching off a little bit earlier than the programmed time. If your home is up to temperature, you will not notice the effect on the temperature, but you should see a difference in your fuel bill.

Changing the Batteries
The Thermostat is powered by 2 x AA batteries, although a battery icon is not shown on the display during normal use. The only time you will see the battery icon is when they become low on power.
- is displayed when battery power has reached approximately 10% – you should be prepared to change them soon.
- will flash when battery power has become critically low – you should change them immediately to make sure there is no disruption to your heating system.
- Replace with 2 new 1.5V LR6 AA Alkaline batteries only – which should last approximately 2 years depending on Thermostat use.

Please help to protect the environment by recycling old batteries in accordance with local regulations.
