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 buttons to 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 protect)

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). If the temperature drops to 5°C, the heating will come on to prevent the heating pipes from freezing.

Press the to switch the heating off – the display will show OFF.
Press the again to switch the heating on – the display will show AUTO or MAN.

Optimisation

Your Thermostat has optimisation functions that aim to save energy while maintaining suitable comfort levels. The Thermostat displays during the optimisation period if set. By default, optimisation is disabled. See the installation guide for instructions 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. A battery icon is not shown on the display during normal use. The battery icon appears only when the batteries become low on power.

The is displayed when battery power has reached approximately 10% – you should be prepared to change them soon.
The +will flash when battery power has become critically low – you should change them immediately to ensure no disruption to your heating system.
Replace with 2 new 1.5V LR6 AA Alkaline batteries only. These should last approximately 2 years, depending on Thermostat use.

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