Range of application
The MST1 thermostat can be used to control floor heating systems such as electric heating mats or heating films, as well as for NC control valves
(normally closed) for water-guided floor heating systems. But other electrical heating devices such as infrared radiant heaters or convectors can
also be operated via the thermostat.
IMPORTANT!: The unit only has the external temperature sensor. This must therefore be connected for operation.
Important notes
•
We recommend leaving the installation of the temperature controller and the heating system to specialists.
•
Only qualified electricians should carry out the electrical connections and the mains connection of the appliance.
•
Disconnect the cables from the power supply before installing, checking or replacing a thermostat.
•
The wiring diagram and installation instructions for the appliance can be found in this manual.
•
The manufacturer's warranty does not cover malfunctions of the appliance that occur as a result of mechanical damage, incorrect
installation, improper handling and use for purposes or conditions not specified in these installation and use instructions.
Safety instructions
Disconnect the cables from the power supply before installing, checking or replacing a thermostat. Work on electrical connections and the mains
connection of the appliance may only be carried out by qualified electricians. Failure to do so will invalidate the warranty. Only plastic flush-
mounted boxes may be used for thermostat installation. During installation of the corrugated pipe and again before laying the screed, make
sure that the sensor can be laid in the corrugated pipe and removed again.

Assembly
Thermostat placement: Place the thermostat on the wall up to a height of 80 to 150cm. In locations with increased humidity, install the
thermostat as far as possible from the sources of humidity according to the applicable standards. Do not place the thermostat on a wall
exposed to sunlight or on the outside wall of the building. Install the floor temperature sensor at least 50cm into the heating surface and
always in the installation pipe (so-called corrugated pipe), which is covered at the end to prevent building material from entering the pipe.
