Regulations and Mounting
Operator unit AVS37
The operator unit is integrated into a
specially designed housing and clicks
into place as shown.
The installation location of the housing
varies depending on the type of heat
pump:
Installation in AQUATOP T
AQUATOP T: The operator unit with
housing is permanently mounted on
the heat pump and wired in the factory.
Installation in AEROTOP T
The operator unit and housing are
packed separately and delivered with
the heat pump.
Indoor installation AEROTOP T
When the AEROTOP T heat pump is
installed indoors, the operator unit is
clicked into place in the opening in the
front panel cut out for this purpose.
Outdoor installation AEROTOP T
When the AEROTOP T heat pump is
installed outdoors, the operator unit is
mounted inside the building on the wall
using the wall mounting plate (A) and
the cover plate (B) is clicked into place
on the heat pump.
The wall mounting plate and cover plate
are part of the outdoor installation set.
B
A
The operator unit is connected to
connector X30 on the base unit using
the connection cable.
The operator unit is connected to
terminals G+, CL-, and CL+ on the
base unit using an intermediate cable.
Regulations and Mounting
Room unit QAA55
Mounting
When the unit is removed from its
base, power is disconnected so
that the unit is out of operation.
Connections
1 CL+ BSB data
2 CL- BSB ground
The room unit should be located in the
main living room while giving
consideration to the following points:
• The place of installation should be
chosen such that the sensor can
capture the room temperature as
accurately as possible without
getting adversely affected by direct
solar radiation or other heat or
refrigeration sources (about
1.5 meters above the floor)
• In the case of wall mounting, there
must be sufficient clearance above
the unit, enabling it to be fitted and
removed
• The controller may not be exposed
to dripping water

Reset functions
The RESET button triggers various functions, depending on
the period of time the button is kept depressed.
Pressing the button for more than 3 seconds triggers manual
defrosting.
Pressing the button for less than 3 seconds triggers a reset.
If an air-to-water heat pump is used, the defrost function for
the evaporator can be triggered manually.
After successful defrosting or on completion of the maximum
permissible defrost time and after the permitted number of
defrost attempts, the heat pump will automatically be released
again.
The RESET button is used to jointly reset pending heat pump
error messages, meters and other resettable parameters. This
bridges the preset switch-on delay in the event of fault, thus
avoiding waiting times during commissioning or fault tracing.
This function should not be used in normal operation.
The reset function for individual parameters appears on the
bottom line of the display, provided a reset is permitted on the
current operating line (enduser / commissioning / heating
engineer).
After activation with the OK button,
the display shows a flashing “Yes“.
After confirmation with the OK button,
