2Designated use
The Multi Therm-C clock thermostat has been designed to control room heaters that work according
to the Argus bus system. This is a two-wire low voltage communication system. The thermostat is not
suitable to switch 24V, 230V or other signals. It may only be used in dry rooms with slight impurities
(degree of protection IP30).

Room thermostat MTC 3/12
Before use, carefully read these operating instructions and observe them. In case the mounting and
operating instructions are not observed, the manufacturer’s warranty will not apply to any resulting
damage.
2.1 Safety
Electrical devices may only be connected by a qualified electrician. Always observe the relevant
national regulations. Interferences and changes to the device will lead to cancellation of the warranty.

4 Mounting and electrical connection
4.1 Mounting
The clock thermostat is suitable for mounting in dry, not too dusty rooms.
Place the thermostat in a room in a location where air can circulate
unimpeded. Beware that in winter the low-standing sun cannot shine directly onto the thermostat.
Placement above or near a device that radiates heat is also not recommended. Avoid placement on a
cold outdoor wall; place the thermostat on an indoor wall free of draught. All these things have an

adverse effect on the correct measurement of the room temperature and hen
operation of the thermostat.
By pressing the notch on the bottom of the thermostat, you can open the thermostat. The bottom plate
containing the connector can be mounted on a universal wall box or directly on the wall.
Be ware that the c
ontroller should not be mounted near a an
communication network. These antennas may disturb the correct functioning of the controller.
Always keep a few meters distance.

4.2 Electrical connection
In all cases the communication between the heater and the
thermostat is based on a two wire, low
the appliance the wire for
the thermostat has to be connected
to connection 4 and 5 (see also electrical wiring diagram).
Connect the thermostat wires to the connector
marked with RT
If the right connector is used the thermostat will
become defect.
Cable specification: signal ca
ble, 1x2x0,8 (shielded and twisted)
Maximum length 200m.
If the cable is chosen too thin, the signal will become too poor. If the cable is not shielded and twisted
the signal might become disturbed in an EMC unfriendly environment.
Keep the thermostat ca
ble separated from mains cables. Connect the earth shield of the cable only to
the earth terminal in the heater.
If these guidelines are not followed it may result in malfunction of the installation or worse, it could
damage the thermostat or the electron

Standard nothing needs to be changed in the heating device. In case the
thermostat does not work, check that the micro
plate in the room heater are set as shown on the right: number
and the other numbers down. The switch S3 should be set to 1. In case
several devices are connected to 1 thermostat, refer to the relevant chapter
in this manual.
This thermostat is only suitable for connection to heating devices specifically intended for this
purpose. Never connect, for example, 24V or another voltage of another system to the thermostat.
This can damage the thermostat.After making the changes insid
plug the power to the heater for the changes to become effective.
4.4
Several units on 1 thermostat
The room thermostat can control up to 8 room heaters. Connecting
them is simple, but it should be done properly.
Pay attention to the following:
•
Each unit must be given its own number (to be set with the
micro-
switch S2 in the unit).
•
One unit must have the S2 number 1 set on ON (this unit
provides for the communication) and S3 to 1, al the other
heaters should have S3 set to 0.
•
Between the separate units, the numbers 4 must be
connected with the numbers 4 and the number 5 with 5. They must not be connected in a
cross-wise manner.
The functionality of the thermostat does not change by connecting a number of room heaters.

19 Internal battery
When the thermostat is connected to the room heater, it does not use power from the internal battery.
This battery only serves to allow the internal clock to run on in case of a power failure. The
programmed data always remains in memory. This means that the battery, too, will stand years of
use.
When the battery is empty, the clock of the thermostat will be on 00:00 after a power failure of the
room heater that has number 1.
