Mode switch for the drinking water heating circuit
Time-controlled operation with option to deactivate
drinking water heating circuit
Time-controlled operation, heating circuit deactivated,
only frost protection active
Heating and drinking water heating circuits deactivated,
only frost protection active
Manual operation: *
Control valve opens inactive closes
(no function in
system 1
; in
system 2
and
3
only
position 0 = drinking water circuit deactivated
po = SLP and, if needed, TLP switched on)
* If the controller only reacts to these switch positions as in deactivated
mode (heating and drinking water heating circuits are deactivated), the
manual level is locked. See chapter 7.3 on page 57 for more details.
Set point correction switch
