Silent Mode (option)
Upon request, the operating function "silent mode" can be upgraded to
the outdoor unit. "Silent Mode" allows a reducing of the fan or compres-
sor speed during defined periods. With the reduced speed the perfor-
mance of the heat pump also decreases. The switching on and off of the
"Silent Mode" can be controlled via WWPR-controller.
Basically you have the choice between
quiet running
(only the fan
speed reduction) or
step mode
(speed reduction of fan and compressor).
Warning! Risk of electric shock!
Do not use water or other liquids to clean the unit!
Keep all electrical supply units locked at all times!
Any work on the electrical equipment of the heat pump shall only be per-
formed by professional electricians!
To realize the function "silent mode" the signal of the multi-function output
terminal is tapped on-X1.6u on the control panel of the indoor unit. It can
be wired to one of the following components (see diagram):
1) Coupling relay 230 V, 1 W, 6 A (Z19141) on the control panel of the
indoor unit (maximum wire length 10 m).
2) Coupling relay 230 V, 1 W, 6 A (Z19141) in the outdoor unit (wire
length greater than 10 m).
3) Switch in the outdoor unit (no control via WWPR control possible).
Required for applications 1) and 2) in addition to the coupling relays ac-
cessories No. Z18064 (plug SE55RA PAC-E for silent mode).
