4.2 Accessories

The following accessories can be used to extend con-

troller functionalities:

2 of 7 multi-functional modules

The multi-function module VR 2 of 7 can be used by the

VRC 430 to control a circulation pump.

VR 61 mixer module

The mixer-module VR 61 extends the VRC 430 function-

ality to include a twin-circuit controller.

Solar module VR 68

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

control a solar installation.

VR 81 remote control unit

The remote control VR 81 is recommended if the

VRC 430 is fitted in the heating unit, or if the second

heating circuit is to be controlled decentrally.

The remote control VR 81 can be used to set the follow-

ing parameters:

– Operating mode

– Target room temperature

Symbols are displayed indicating maintenance and error

messages.

Data interchange is via eBus line.

Note!

If accessory components are connected to the

VRC 430, the instructions for these compo-

nents must also be observed.

4.3 Location

The controller should only be installed in dry rooms.

If the controller is mounted on the wall, it should be fit-

ted in such a way that the room temperature is meas-

ured properly; e.g. on an internal wall of the main living

room, at a height of approx. 1.5 m

If the thermostat function is activated, advise the opera-

tor that all the radiator valves must be fully open in the

room where the controller is mounted.

See Chapter 4.6 for information on locating the outdoor

sensor.

4.4 Fitting the controller in the heating unit

Danger!

Live connections!

There is a danger to life from electrocution

when working on the electronics box of the boil-

er.

Switch off the power supply to the electronics

box of the heating unit and secure against re-

connection before carrying out any work.

Only open the electronics box if the heating

unit is disconnected from the power source.

Proceed as follows:

⇒ Switch the boiler off.

⇒ Turn off the power supply to the heating unit and

secure the power supply against re-connection.

⇒ Remove the front screen from the heating unit.

⇒ Carefully press the controller (without wall plinth,

see Fig. 4.1) with the pin rail into the plug connector

on the heating unit.

⇒ Now fit the external sensor (see Chapter 4.6), if not

already done.

⇒ Carry out the electrical installation of the external

sensor as described in Chapter 5.2 or 5.3.

⇒ Re-connect the power supply to the heating unit.

⇒ Switch the heating unit on again.
