Return temperature control
selection (applies only if 5 – 3
adjustment is not set at 0)
Option 1: The boiler circuit pump operates continuously during
the heating season; return temperature control by the heating
circuit mixing valves.
Options 2,4 and 5: Return temperature control by shutting off
the boiler pump. This can only work with large water contents in
heat exchangers. Do NOT use these options with Remeha
boilers
Option 3: a mixing circuit is added (pump and mixing valve. The
green heating circuit of the controller commands both pump and
mixing valve of this circuit.
Option 6: this option allows return temperature control by means
of one single mixing valve for all boilers in a multiple boiler
installation. Because of the complexity of the hydraulic
installation, we do not recommend this option.

Allocation of relay outputs
Master controller programming will determine which relay (in
which slave controller) will command each switching boiler.

12 ELECTRICAL WIRING
12.1 Slave controller connection
All slave controllers and their extension sets M4 or M5
must be connected to the application bus. These are
clamps nr. 1 and 2 on the adapter. Be sure there is no
wiring inversion!
12.2 Sensor print application
The adapter, which is contained in these sets, does have
NO connection possibilities for analog remote control
FS 3611, a room sensor ZRF 3601 or a party switch.
For these applications, a sensor print (art. nr. 49.494)
must be fitted. All low-voltage connections will have to
be made on the sensor print instead of the adapter (see
Fig. 01)
