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!

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.
Master controller programming will determine which relay (in
which slave controller) will command each switching boiler.
Choose a method for sequence changeover. Information.
Maximum limit cascade temperature.
Description
Remote control with incorporated room sensor FS3601 of the green circuit
Room sensor of the green circuit (ZRF 3601)
Outside sensor (ZAF 200)
Flow temperature sensor for the green circuit (ZVF 210)
Boiler/common flow sensor (ZTF of ZVF)
Calorifier sensor (ZTF 222)
Return sensor for return temperature control (ZVF 210)
Remote control with incorporated room sensor FS 3601 for red circuit
Outside sensor (ZAF 200)
Flow temperature sensor of the red circuit (ZVF 210)
Room sensor for the red circuit (ZRF 3601)

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)
