4.2 Accessories

The following accessories can be installed in addition to

the VRC 430f weather compensator:

2 from 7 multi-functional module

The VRC 430f can control a circulation pump via the

multifunctional model 2 of 7.

Mixer module VR 61

The VR 61 mixer module expands the VRC 430f so it has

the functionality of a dual circuit controller.

Solar module VR 68

The VR 68 solar module can be used by the VRC 430f

to control a solar installation.

Note!

If the VRC 430f is connected to additional

components, please observe all instructions in

relation to those components.

4.3 Installating the unit

Only install the controller and the radio receiver unit

in dry rooms.

The controller should be fitted so as to ensure prob-

lem-free measurement of the room temperature;

e.g. on a room wall of the main living room at a

height of approx. 1.5 m.

Before you install the controller and wireless out-

door sensor, check the intended locations for possi-

ble functional impairment of the radio signal path by

electrical devices or building components. If inter-

ference in the signal path is likely, an alternative in-

stallation location must be found.

If the switch-on room temp. is activated, advise the

user that, in the room where the controller is

mounted, all the radiator valves must be fully open.

See Section 4.5 for the mounting location of the wire-

less outdoor sensor.

4.4 Installing the wireles transmitter in the

heating unit

ance is disconnected from the power source.

Proceed as follows:

Switch off the appliance.

Turn off the power supply to the appliance and se-

tentionally switched back on.

Remove the front panel on the appliance and re-

move the cover plate on the control cabinet.

Push the radio receiver unit into the plug connec-

tion provided in the control cabinet using your plug
