The operating module Merlin BM, BM 8 and Lago FB
(Only for controller models with CAN-Bus connection)
Electrical connection: Connector [16+17+18+19]
The controller permits connection, via a bus line, of an
operating module Merlin BM, BM8 and Lago FB for each
heating circuit. The operating module allows various
operation control functions and monitoring functions for
the system values to be relocated to the main controlled
zone – i.e. the living room.
This achieves maximum comfort and convenience.
A detailed description of the entire functional range is
found in the technical descriptions of the operating
modules.

i
Standby/OFF (frost protection only)
q
1
Automatic mode (acc. to timer program 1 in controller)
q
2
Automatic mode (acc. to timer program 2 in controller)
C
24-hour night operation (reduction temperature)
B
24-hour daytime operation (comfort temperature)
F
Summer mode (heating OFF, hot water only)
Depending on the version, your FBR supports a portion of
the following operating modes.
!
The operating mode at the controller must be set to
q
.
The controller can also be operated with an FBR1.
Telephone switch
The heating system can be switched to Heating mode
h
with a telephone switch. The connection terminals of the
controller for the remote control FBR (see connection
diagram) are used for installation. As soon as a short
circuit is detected between terminal ([5+GND at Hc1] and
[13+GND at HC2], the associated heating circuit switches
to heating circuit. Additionally the hot water preparation is
activated (only for controllers with hot water preparation).
When the short circuit is eliminated, the controller once
again heats on the basis of the set heating program.
E
If the heating circuit is controlled remotely by an
operating module, the telephone switch must be
connected at the operating module.
DCF receiver
Electrical connection: Terminal [14, 15]
The controller can evaluate an eBUS DCF receiver on the
eBUS FA-Terminals.
If the DCF receiver is connected, the controller time is
updated as soon as the DCF transmits a valid time on the
BUS.
