You can set the times at which the optional circulation
pump is operational in the Circulation pump time pro-
gramme menu.
Up to three times can be programmed per day or block.
If the operation mode "ON" is set for domestic hot water,
the circulation pump runs continuously (¬ section 4.11.1,
menu 4).
The circulation pump time programme should correspond
to the
hot water time programme; if necessary the time windows
can be selected even more restrictively.
If the desired hot water temperature is obtained quickly
enough without switching on the circulation pump, the cir-
culation pump can likewise be disabled.
In addition, you can briefly activate the circulation pump by
means of pushbutton switches mounted in the immediate
vicinity of the draw-off points and connected to the heat
pump (the same idea as stairwell lighting). The operating
times of the circulation pump can thus be optimally
matched to the actual need.
Consult your heating engineer about doing this.
