CLASSIFICATION
The product is a class II device (reinforced
insulation) and the product must be connected
to the following conductors:
1) Phase (L)
2) Neutral (N)
WARNING – Important Safety Instructions
Isolate supply before carrying out any
installation or maintenance work on this control
unit and associated components. This control
unit and associated components should only be
i
nstalled by a competent person (i, e qualified
e
lectrician). Electrical installation to be in
accordance with latest IEE Wiring Regulations
a
nd appropriate Statutory Regulations.
M
ounting of sensor
Floor sensor: Placed in an approved non
c
onductive installation pipe in accordance with
E
N 61386-1, which is embedded in the floor.
(fig. 4) The pipe is closed in the end and placed
as high as possible in the concrete layer. The
i
nstallation pipe must be centered in between
t
he heating cable.
Sensor cable can be extended up to 100 m. by
means of a separate cable. If the extension
c
able is lighter than H05VV-F, it shall equally be
i
nstalled in an unbroken installation pipe
between the sensor cable and the extension
c
able. Two remaining cores of a multi-core
c
able which, for example, supplies current to
the floor heating wires, must not be used. The
s
witching peaks of such current supply lines
may create interfering signals that prevent
optimum controller function. If a shielded cable
i
s used, the shield must not be earthed but
must be connected to terminal 7. The two-core
cable must be placed in a separate pipe.
PLACEMENT OF THERMOSTAT WITH BUILT-
IN SENSOR
Thermostat is to be mounted on the wall with
free air circulation around it (fig. 5). Furthermore
it has to be placed where it is not influenced by
any other heating sources (e.g. the sun), draft
from doors or windows, or by the temperature
of an exterior wall.
OJ Microline units contain a fault interrupter
circuit which interrupts the heating in case of
disconnected or short-circuited sensors.
MOUNTING OF THERMOSTAT (fig. 1-3)
1. Remove the control knob (A).
2. Screw (B) should be unscrewed and the
cover lifted off.
3. Electrical connections can be made as
shown in the wiring diagram.
4. Mount the backing plate. Use only the round
holes.
5. The thermostat can now be filled into the
wall box.
- frame and cover is mounted
- thermostat knob is replaced
SETBACK TEMPERATURE
Setback of temperature setting is activated by a
230 V (L) signal from an external time switch to
terminal 5. Setback temperature is fixed 5˚C.
TEMPERATURE SETTING
OJ Microline has a scale range of +5/+40˚C. To
assist the adjustment, the thermostat has a LED
(D) which will glow RED when the heating is ON.
The thermostat should be set to maximum
temperature setting until the desired
temperature of the room or floor is achieved.
The control knob should then be turned back
until the LED goes out. Fine adjustments can be
made over the next 1/2 days to suit individual
requirements.
THERMOSTAT ADJUSTMENT
When the room temperature has been
stabilized, the thermostat set position may be
adjusted to match actual room temperature.
M
easure the temperature of the room with an
a
ccurate thermometer. Remove control knob
and reposition it so that the indicated
t
emperature line shows the same as the
m
easured temperature. This adjustment can be
d
one in steps of 3°C.
M
AX./MIN. TEMPERATURE
A
locking mechanism is positioned behind the
control knob to limit the amount of adjustment
possible. By loosening the little screw (C), the
s
cale range can be locked, e.g. between 20˚C
a
nd 25˚C. The red ring indicates the maximum
temperature and the blue ring indicates the
minimum temperature.
