The dials on the right can change the water temperatures of the domestic hot water and the hydronic system.

You can programmer every single day, or batches of days.
We suggest you programme Mon – Fri the same and Sat and Sun the same.
Each day can have 4 periods and all 4 periods need to be programmed. If you want to use less that 4 simply set the periods that you aren’t using to come on and off at the same time.
