The time switch program can be set with the QAW70 room unit.
But this is possibly only if operating mode Auto
is selected on the controller.
Free time switch program
•
The free time switch program serves as a switching criterion for a number of func-
tions.
The time switch program consists of switching times that can be entered for the week-
days or the 7-day block.
It operates independently of the time switch programs for space heating and d.h.w.
The free time switch program can have an impact on the following functions:
•
Forced charging of the buffer storage tank with the heat pump (operating line 475)
•
D.h.w. circulating pump (operating line 772)
•
Auxiliary functions 23, K13 (operating line 169)
•
Additional pump kick for water / brine pump (operating line 427)
