Electrical connection

Note: During service work, isolate the entire system from the power

supply, otherwise there will be a risk of electrocution.

Maximum thermostat When connecting the maximum thermostat at the "Max TH"

terminals of the KM, only the mixer circuit pump will be stopped

in case of faults (mixer no longer closes).

Without a maximum thermostat, extremely high temperatures may

occur in the under oor heating circuit, should the KM develop a

fault. This can result in the  oor developing cracks. If with the

con gurations 1, 2, 3, 4, 5, 7, 8 and 13 no maximum thermostat is

connected, plug a 3-pole Rast5 plug with jumper in its place.

Fault message input With all con gurations except con guration 5, the grey 2-pole

plug with jumper must be plugged into input "E2" if the fault input

is not used.

Outside temperature

sensor

There are four options for integrating an outside temperature

sensor into a system:

a) Outside temperature sensor at boiler 1 (address 1) at terminal

AF, part no. 2792021.

b) Outside temperature sensor at BM (address 0) in the wall

mounted base at terminal 5/6, part no. 2792021.

c) Radio clock module with outside temperature sensor connected

to the eBUS, part no. 2792325.

d) Wireless outside temperature sensor and radio receiver

connected to the eBUS, part no. 2744081 and 2744209.
