energy supply should be switched off during installation and only qualified
people should
mechanical damage.
a) fixing the controller:
• fix the controller on a wall and other support with the use of two screws (rawbolts with
screws come with the regulator),
• attach the cables lead out of the controller to the wall with the use of grips.
b) fixing sensors:
• sensors must not be immersed in liquids and installed on exhaust fume outlets
to the chimney,
• install boiler temperature sensor in an appropriate place on the boiler or in an
uncovered part of central heating pipe (as close to the boiler as possible),
• install temperature sensor of the tank in an appropriate place in the tank,
• press the sensors to the pipe with the use of bands, put thermal insulation on.
c) connecting supply cables to the pumps:
• connect yellow or yellow-green conductor (protective cable) to the clamp (
• connect blue conductor to the clamp (N),
• connect brown conductor to the clamp (L),
d) checking the connection:

• after securing cables against accidental rupture, connect power supply cable to
230V/50hz socket with earthing pin.
Ambient temperature in controller installation place should not exceed 40ºC.
