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)
MOUNTING OF SENSOR
Floor sensor: Placed in installation pipe which is
embedded in floor (fig. 4). The pipe is thickened
in the end and placed as high as possible in the
concrete layer.
Sensor cable may be extended up to 50 m with
separate cable for power current. Two
conductors in a multiconducting cable, which
Elektra type OTN
e.g. is used for supply of heating cable, may not
be used. Voltage signals, which may disturb the
function of the thermostat, may occur. If the
cable is used with screen, the screen may not
be connected to the ground, but must be
connected to terminal 7. The best installation is
attained with a separate cable for the sensor,
which is then mounted in a separate conduit.
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.
OTN contains 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. 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
OTN 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.
Measure the temperature of the room with an
accurate thermometer. Remove control knob
and reposition it so that the indicated
temperature line shows the same as the
measured temperature. This adjustment can be
done in steps of 3°C.
MAX./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
scale range can be locked, e.g. between 20˚C
and 25˚C. The red ring indicates the maximum
temperature and the blue ring indicates the
minimum temperature.
