Which Timer Mode is Best for Me?

The heater leaves the factory set in 

Out All Day

 mode. If you are out during the day and only require heat 

in the mornings and evenings then this mode will suit your lifestyle and you won’t need to alter anything. If 
you are in during the day then you should select the 

Home All Day 

mode which is a single heating period. 

The times of these modes can be modified, or the 

User Timer

 mode can be used to give you four periods of 

heating split throughout the day. If you are away for an extended period then you can use the 

Holiday

 mode. 

This allows you to reduce the heating during the period that you are away, reverting to the previously selected 
mode on the day you return.
