Regtronic EM as module 1 for mixed heating circuit 2
The Regtronic EM is an extension module which can be connected to a
Regtronic
RM
,
Regtronic RS
,
Regtronic RH
or
Regtronic RX
controller.
All adjustments for the extension module menu are to be carried out on the controller.
In the following, the step-by-step adjustment in combination with the
Regtronic
RH
controller is described.
In this example, the extension module is used for controlling a second heating cir-
cuit. The outdoor temperature sensor (S2) and the optional backup heating demand
(R5) of the Regtronic RH are available for both heating circuits.
For initial commissioning, proceed as follows:
Î
Connect the EM to the controller by means of the S-Bus cable.
Î
Connect the flow sensor, pump and mixer of the second heating circuit to the
extension module (see table).
