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,

the relevant parameter or meter will
