DEVI Devireg 330 Operating and maintenance manual

AUS Installation and Use Instructions
the devireg
TM
330
16 Amp. Thermostat
PLEASE NOTE
The enclosed Floor Sensor MUST be installed so that it
may be REMOVED for service if required!
The sensor probe should be installed into a conduit with
no more than one wide-angle bend. This should be
installed from the floor to the thermostat or junction box
located directly above the heated area.
PLEASE READ ENCLOSED INSTRUCTIONS

Application:
The devireg
TM
330 is used for the control of room
temperature, refrigeration systems, floor temperature, frost
protection, snow melting, industrial purposes and roof
gutter installations.
Installation:
The devireg
TM
330 is an electronic thermostat with a 5
o
C
temperature set back. It is designed for installation into
Panel Boards with an overall minimum height of 52mm, as
well as for DIN rail attachment.
1. The installation must be permanent. The devireg
TM
330
must be mounted after an external switch or circuit
breaker.
2. The set temperature can be lowered (set back) by 5
o
C
when terminal 6 is short-circuited by means of an external
switch or time switch.
3. Thermostat must be attached to a vibration-free
surface.
4. If the air sensor is used, it must be mounted on an
internal wall approx. 1.5m above the floor. It must not be
located in the immediate vicinity of radiators, doors,
windows or anywhere where the thermostat could be
exposed to direct heat or draughts etc.
5. The connection between the floor or air sensor should
be made using 1.5mm
2
2-core cable. The cable length can
be up to 50m without affecting the accuracy of the
thermostat. The cable must not be placed parallel to high
voltage cables as this can induce undesirable signals. It
must not be in the same conduit as the heating circuit
wiring.
6. If the sensor is to be cast to the floor or will be exposed
to pressure the sensor MUST be installed into a conduit
with no more than one bend.

7. Contactors or other objects producing strong
electromagnetic fields must not be placed in the
immediate vicinity of the thermostat.
8. Connections should be made according to the circuit
diagrams (see figs 1&2).
Loads over 16 Amps must be controlled via a contactor,
fig. 4. The correct Contactor size depends on the total
load of the heating elements for the zone. Ensure that the
Contactor selected is suitably sized. Some Contactors can
be wired to share the load between contacts, however this
should be confirmed with the manufacturer.
If a number of Contactor/Circuit Breakers are mounted
close together, adequate ventilation space must be
allowed. As the devireg
TM
330 is not equipped with a
separate Earth Terminal, the earthing screen of the
heating cable must be connected to the household Earth.
The 'Cold Tails' from the floor have a center core that
is called the cold tail conductor. This conductor is
surrounded by an earth braid/shield.

Trouble Shooting
Function:
If activating the thermostat does not turn on heating,
check all the circuit breakers including the RCD
before contacting your Electrical Contractor.
Trouble-shooting chart:
For the Electrical Contractor only!
Function
- Control mains voltage on terminals 3 and 4.
- Tighten up load terminals 1 and 4
- Measure the resistance in the heating cable and
calculate the output:
P= V2 =57600 W (at 240 V~)
R R
The calculated output of the heating cable can be
determined by looking it up in your DEVI catalogue.
- If the sensor wire terminals 7 and 8 are removed,
the red indicator lamp should light up and the
thermostat should switch ON. If not the thermostat
is faulty.
- Measuring the Sensor with an Ohmmeter should
give a stable resistance compared to the ambient
temperature – see Technical Data Chart
- If the sensor access – terminals 7 and 8 – is short-
circuited, the green indicator lamp should light up
and the thermostat should be switched off.
If not, the thermostat is faulty.
