Cylinder temp. Current: Current temperature in the
domestic hot water cylinder.
We recommend that DHW loading be achieved without an
external auxiliary heater. By this method, the maximum hot
water temperature is determined by the control pressure
lock-out in the heat pump coolant circuit. This lock-out cor-
responds to a maximum hot water temperature of 55 °C.
i
In order to keep the heat pump starts to an
absolute minimum, as low a minimum hot water
temperature as possible should be selected.
You can set the times at which the domestic hot water cyl-
inder is heated in the DHW loading time programme menu.
Up to three times can be programmed per day or block.
The generation of hot water should only be active at times
when really hot water is to be run. Please set this time pro-
gramme to your minimum requirements.
As an example, working people can set a window from 6.00
– 8.00 hrs. and a second window from 17.00 – 23.00 hrs.in
order to minimise the energy consumption for DHW loading.
