previous programmed by pressing once. You can now copy that day
across to the next day by pressing and holding and until setting flashes up

pressing and holding and as before, until you have programmed the week or

Push and hold until settings flashes up on the controller.
Please remember to use button to go back a menu, until back to main screen
if required.
Note: If turning the space heating off in the schedule timer it may prevent the unit from
switching back on by the schedule timer. This is not a fault, the schedule timer has to be
adjusted so the unit never has an off function. Just change the desired room temperature
set point i.e. 16°C; or even reduce the water flow temperature down to 25°C to make sure
the unit is only required to maintain a background temperature. This will allow you to switch
off the space heating schedule timer in the summer months by switching to off,
allowing the domestic hot water schedule timer to carry on operating as before.
Once all the schedule timers have been programmed use until you are back to the
normal remote controller screen.
Activating the schedule timer
To activate the schedule timer push and the clock will be displayed on the left
hand side of the controller. Push it again and the clock symbol will disappear from the
controller deactivating the schedule timer.

Additional information
Last command
If there is no external room programmable thermostat, the controller works on last
command basis i.e. if you change the water flow temperature or desired room temperature,
then this will stay the same until it is either changed or there is an action programmed in
the schedule timer such as water temperature change or off function.
Domestic hot water mode
It is possible to boost the domestic hot water if a shortage occurs. This setting will override
any current setting at the time of operation. To activate the domestic hot water boost mode
press and hold until the symbol starts flashing. This setting will deactivate once the
domestic hot water has reached its set point.
