Warmer/cooler function
The room temperature can be temporary set to
warmer or cooler for each living zone using room
units QAA74 and operator units (HMI) AVS74.
The setting is only temporary. lt cannot permanent-
ly influence any parameters.
The warmer/cooling function is initiated on the
temperature side of the unit using the push and
roll knob.
Three settings are available:
• Cooler starts the cooler function
• ..... neutral position
• Warmer starts the warmer function
If the warmer function is initated in the comfort
phase - the room setpoint is increased by 1K and
at least 1K above the room actual value, or the
room model value.
If the warmer function is initated in the reduced
phase - the room setpoint is set to the comfort set-
point and at least 1K above the room actual value,
or room model value.
In the cooler function - regardless the phase - the
room setpoint is reduced by 1K and at least 1K
below the room actual value, or the room model
value.
The warmer/cooler function ends automatically at
the next operating level changeover by time switch
program or at midnight, at the earliest, however, after
2 hours (function time). It can also be ended manually
by returning the settings to the neutral position “.....”.

Setpoints
The different setpoint setting ranges are interlocked,
which means that the next lower setpoint cannot
be higher than the next higher, and vice versa.
The individual setpoints required for each heating
circuit can be adjusted.

The “Comfort” setpoint is the room temperature
setpoint for normal room usage (e.g. during the
day). lt is the setpoint used when the plant oper-
ates in Automatic mode (during the Comfort phase)
and in Comfort mode .
The setpoint recommended for heating in terms of
comfort and energy efficiency lies typically between
20 and 22 °C.
The
“Reduced” setpoint is the room temperature
setpoint for non-occupancy time (e.g. during the
night or when absent for several hours). lt is used
as the setpoint when the plant operates in Auto-
matic mode (during the Reduced phase) and in
Reduced mode .
The
“Protection” setpoint is the room temperature
setpoint for the periods of time when the room is
not occupied (e.g. during holidays), but protection
from extremely low temperatures shall be provid-
ed for the hydraulic system or animals and plants,
antiquities, etc. lt is used as the setpoint when the
plant operates in Protection mode.
“Comfort setpoint max” ensures maximum lim-
itation of the adjustable “Comfort” setpoint. The
“Comfort” setpoint cannot be set to a level higher
than the level defined here.
