Maximum delimiter
If a maximum delimiter is required it must be connected
between the heating circuit pump and the pump controller
switch output.
Connector I, terminals 4 and 5
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 dia-
gram) are used for installation. As soon as a short circuit
between terminal 3 of the FBR and ground (FBR terminal
2) is detected, the assigned heating circuit is switched to
heating mode. Additionally the hot water preparation is ac-
tivated (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.
