Temperature sensor checking
Temperature sensors CT10, CT6-P can be
checked by measuring their resistance in
given temperature. In case of big differences
between measured resistance value and
values in table below, the sensor should be
replaced with a new one.

Connecting a room thermostat
Room thermostat (NO-NC) connected to the
control affects the heating circuit.
The thermostat after contact opening reduces
the preset temperature heating circuit about
the service value Decrease of thermostat or
can turn off the pump in the parameter Off by
thermostat. The values of the parameters
must be chosen so that when of working the
room thermostat (contact opening) the
temperature in the room dropped.
Connecting a heat source
COM-NO terminals are used to connect the
contact heat source (no voltage) that turns on
and off the heat source. The heat source can
be automatic boiler gas or oil, which has a
contact ON-OFF. Terminals COM-NO does not
have galvanic isolation of 230V ~ and can
therefore only serve to disconnect circuit
voltage of 230V ~. Use separate relay in the
event of having to disconnect circuits at low
voltage.
Risk of electric shock caused by
current from a heat source.
Disconnect the controller and
heat source electrical supply and
make sure there is no dangerous
voltage on terminals.
Protect yourself against incidental
generation of supply voltage!
Connection to heat source (gas or oil boiler)
should be done by a qualified installer,
according to technical data of this boiler.
