DEVI Devireg 330 - Installation

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.
