between the heating circuit pump and the pump controller
switch output.

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 is
detected at terminals 2 and 3 of the corresponding con-
nector, the assigned heating circuit switches to heating
operation.Additionally, the hot water preparation is activat-
ed. (Boiler controller) When the short-circuit is eliminated,
the controller resumes heating on the basis of the set heat-
ing program.

operating module, the telephone switch must be
connected at the operating module.
