Thermostat
The thermostat must be installed on a DIN standard rail (EN 50022-35) in a
normskåp with the applicable encapsulation class. The thermostat is IP20 classed
and intended for installation in environments with a temperature range of -20°C
to +45°C.
The thermostat has 14 terminal blocks numbered according to the wiring diagram
unit is connected to 9 and 14.
Sensor
If the thermostat is going to be used as a loor heating thermostat, connect the
room sensor as A, and the loor sensor as B. If you are installing a loor that requires
over heating protection, connect the room sensor as A and the over heating
protection as B.
Install the loor sensor in a spiral tube recessed in the loor. The end of the tube
must be sealed to facilitate possible replacement of the sensor.
Place the room sensor so that it is not exposed to direct sunlight or draught. If the
room sensor is installed in an appliance box, it must be sealed to prevent the air
temperature being afected by draught.
For other types of operation and control, the temperature sensor can be installed
as either A, B or A+B. For operation type max/min, the moisture sensor can also be
installed as sensor C. You give the location of the sensor in the START MENU. The
high temperature sensor is recommended for temperatures above +75°C. Only
one high temperature sensor can be connected. It must always be connected as
B, terminal block 7 and 8.
