CONNECTION OF TEMPERATURE SENSORS
Immersion sensor
Immersion sensor is intended to be installed into immersion tube in boiler, heat accumula-
tor, d. h. w. storage tank, solar collectors or elsewhere. Ensure proper contact between
sensor and tube. Secure the sensor with a fastener or a screw.
Surface sensor
Install the surface sensor onto the stand-pipe above the bypass pump or after the mixing
secure it with the enclosed clip spring.
Outdoor temperature sensor
Install the outdoor temperature sensor onto the facade facing north or north-west, approxi-
mately 2 m above ground. Installation above the windows, vents or on the facade facing
south is not allowed.
First remove the protective cover and unscrew two screws from the cover. Use the en-
through cable inlet at the bottom side and connect it.
Room temperature sensor
Install the room temperature sensor onto an indoor wall in a living area, where is not sunlit
and enough distant from sources of heat and wind. Remove the cover and screw the base
onto the selected spot approximately 1.5 metres above ground. You can also install it onto
wall box or directly onto a wall. A 2-wire signal cable is required for electrical connection.
If there are thermostatic valves installed onto radiators in the room, where room unit is
located, the thermostatic valves have to be fully opened. If room sensor is connected to
terminal T1, the required parameter setting is S1.4=1. If room sensor is connected to termi-
nal T8, the required parameter setting is S1.5=1 or S1.5=4.
