Connecting the supply
The exhaust air module is connected to an earthed single
phase wall socket or a permanent installation. For per-
manent installations, FLM S45 must be preceded by a
circuit breaker with at least a 3 mm breaking gap.
Circulation pump for brine (GP2)
Disconnect the PWM cable from terminal block AA5-
X2:7-8. Insulate the wires properly.
Connecting communication
For installation with another heat pump, do not connect
the communication cable (W6).
The DIP switch (AA5-S2) must be set as follows.

OPTIONAL CONNECTIONS
Room sensor for FLM cooling
For optimum function, a separate room sensor (AZ10-
BT50) should be connected when installing with cooling.
This sensor is placed in the room that is to be kept
coolest. The room sensor has up to three functions:
• Offers the opportunity to set a different target temper-
ature in the room that is to be kept coolest.
• Show current room temperature in the display on the
heat pump.
• Provides the opportunity to activate FLM cooling.
Install the sensor in a neutral position where the set
temperature is required, 1.5 m above the floor. It is im-
portant that the sensor is not prevented from measuring
the correct room temperature, for example by being
located in a recess, between shelves, behind a curtain,
above or close to a heat source, in a draught from an
external door or in direct sunlight. Closed radiator ther-
mostats can also cause problems.
Connection of room sensor for FLM cooling
Room sensor (AZ10-BT50) is connected to any AUX in-
put (AA2-X28:3-11) and to GND (AA2-X29) in the com-
patible main product.
