Programming Logic
When programming this thermostat you will be asked to enter a time and then the temperature you require at that time. You can set 4 time/
temperature switches through a single day.
E.g. 07:00 & 22°C > 10:00 & 18°C > 15:00 & 22°C > 22:00 & 18°C
With these temperature settings, the heating will be increased to 22°C by 07:00 and maintain that temperature until 10:00 when the
temperature requirement will switch to 18°C. This new temperature will be maintained until 22°C is required at 15:00, 22°C will be maintained
until 22:00 when only 18°C is required. This last time setting will maintain the specified temperature until 07:00 the next morning*.
