Consider the convenience of an optional 7 day timer
A 7 day timer option is available for some heat pumps which allows a complete week to be pre-programmed, including the weekend, which is likely to have a different operating pattern than the rest of the working week. The 7 day timer can be programmed, for example, to automatically pre-heat your room 60 minutes before you get up in the morning at 6.30am, then turn off when you leave at 8.00am, turn on at 5.00pm to pre-heat your room for your return from work at 6.00pm and automatically turn off at 10pm when you retire for the night.
