WARNING – Important Safety Instructions
Disconnect the power supply before carrying
out any installation or maintenance work on this
unit and associated components. This unit and
associated components should only be installed
by a competent person (i.e. a qualified electri­cian). Electrical installation must be in accord­ance with appropriate statutory regulations

INSTALLING THE RELAY MODULE

The Relay module is designed for flush mount­ing in a wall socket or in the accompanying
mounting box.

Fig. 1:

1. Slide the power button down to O “0”.

2. Release the front cover ONLY by inserting a
small screwdriver into the hole on either side
of the Relay module.

Fig. 2, 2a eller 2b:

3. Connect the wires in accordance with the
diagram.

4. Mount the unit in a wall socket or the accom­panying mounting box.

5. Fit the frame and carefully press the cover
onto the Relay module. Ensure that both
the power slide button on the cover and the
power switch pin are down.

DO NOT open the Relay module by releasing
the four fixing clips on the back.

APPLICATION

The relay module can be used for three dierent
control types: Night setback, Frost protection or
with an external floor sensor.

Fig. 2: Night setback

Connect the heating panel to terminal 4. The
relay module sets the heating panel in setback
mode according to the time programmed in the
4-event time schedule from the Central Control­ler (most heating panels have a built-in ”night
setback input-connector”).

module to frost protection.
The relay module enters frost protection mode
and uses the built-in room sensor to maintain
the frost protection temperature.
In frost protection mode, the relay module
ensures that the heating panel maintains the
setpoint set on the Central Controller.

Fig. 2b: Thermostat with external sensor

Connect a floor sensor to terminals 5 and 6.
Now the relay module works as a thermostat
controlling the heating according the floor
temperature.
The relay module controls the temperature ac­cording to the 4-event time schedule from the
Central Controller.

MOUNTING THE RELAY MODULE

The accompanying mounting box makes it
easy to mount the Relay module on the wall.
Draughts and direct sunlight or other heat
sources must be avoided.

Fig. 3:

Observe the minimum distance of 0,5m, from
large metal surfaces, electronic equipment,
electric motors, etc.

Fig. 3a:

To ensure good signal transmission the unit
should be mounted as high as possible.
The unit should be mounted min. 0,5m above
the floor, away from the heating source, in such
a way that the unit is unaected by the floor
heat.

Fig. 3b:

To ensure good wireless transmission without
interference, all wireless units in the Comfort
System CS4
min. 1,0m between them.
