1

Backup heater contactors K1M, K2M and K5M (optional)

2

Main PCB

The main PCB (Printed Circuit Board) controls the functioning of
the unit.

3

Booster heater contactor K3M (only for installations with domestic
hot water tank)

4

Booster heater circuit breaker F2B (only for installations with
domestic hot water tank)

The circuit breaker protects the booster heater in the 

domestic

hot

 water tank against overload or short circuit.

5

Backup heater circuit breaker F1B (optional)

The circuit breaker protects the backup heater electrical circuit
against overload or short circuit.

6

Terminal blocks

The terminal blocks allow easy connection of field wiring.

7

Cable tie mountings

The cable tie mountings allow to fix the field wiring with cable
ties to the switch box to ensure strain relief.

8

Terminal blocks X3M, X4M (only for installations with domestic hot
water tank)

9

PCB fuse FU1

10

DIP switch SS2

The DIP switch SS2 provides 4 toggle switches to configure
certain installation parameters. See 

"DIP switch settings

overview" on page 14

.

11

X13A socket

The X13A socket receives the K3M connector (only for
installations with domestic hot water tank).

12

X9A socket

The X9A socket receives the thermistor connector (only for
installations with domestic hot water tank).

13

Pump fuse FU2 (in line fuse)

14

Pump relay K4M

15

Transformer TR1

16

A4P

Solar/remote alarm address card (only for installations with solar
kit or remote alarm kit)

17
