3.4.10 Quite Mode
Quite Mode means that the exterior heat pump unit is operating
at reduced output. This reduces the operating noise caused by
the exterior heat pump unit.
CAUTION!
Active Quite Mode reduces the performance in room
heating and room cooling operation with the result that
it may no longer be possible to reach the preset target
temperatures.
●
With outside temperatures below freezing, there is
a risk of material damage caused by frost.
The Quite Mode is set and turned off as follows:

3.5.1 Manual Operation
The manual mode serves to regulate the ROTEX HPSU compact
manually to a specific flow temperature. The manual mode
should only be used for diagnostic purposes.
With hydraulically controlled priority operation for the hot water
generation you must make sure that the flow temperature set in
manual mode is adequate to achieve the stored hot water set
temperature (parameter [T-DHW Setpoint 1]).
During active manual mode the hot water is consistently regu-
lated to the first set value parameter of hot water generation
([T-DHW Setpoint 1]).
When the manual mode is ended, the Control RoCon HP auto-
matically switches to the operating mode
"Standby"
.
