The thermostat is free of maintenance.
Control pollution degree: 2
Pollution degree 2 is representative of normal
household air circulation.
Overvoltage category: III
Rated Impulse voltage 4 kV according to IEC.
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: The floor sensor is used for
temperature regulation in floor surfaces. The
floor sensor must be placed centre of the
heating cables. The sensor wire must not cross
or touch any of the heater wires (fig. 3).
Sensor cable may be extended up to 50 m with
separate cable for power current. Two
conductors in a multiconducting cable, which
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.
OTN-1991-WA units contain a fault interrupter
circuit which interrupts the heating in case of
disconnected or short-circuited sensors.
MOUNTING OF THERMOSTAT (fig. 1-2)
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-1991-WA 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.
Environment and recycling
Please help us to protect the environment by
disposing of the packaging in accordance with
the national regulations for waste processing.
Recycling of obsolete appliances
Appliances with this label must not
be disposed off with the general
waste. They must be collected
separately and disposed off
according to local regulations.
