WARNING !
Cables supplied with the regulator are designed for conducting maximal
load of 2.5 A.
If devices to be connected require more power, the cables need
to be replaced with cables of the appropriate cross-sectional area.

The controller in the Dual Sensor
(DS)
version
(with an additional temperature sensor)
A controller fitted with an additional socket enables connecting an
external temperature sensor (2.5 m is supplied).
In order for the external sensor to be properly detected, first the
sensor must be connected and then the supplied batteries must be
installed in the controller.
After the controller with an additional sensor is switched on, it is
possible to set the maximum temperature of the external sensor in
the range of 10 to 55 deg. C.
In order to check the temperature of the external sensor measured
by the controller, press the OK button for a short time; the measured
value will blink for 5 seconds.
With the additional external sensor connected, the controller will
maintain the temperature according to the air temperature (the
temperature of the internal sensor) and the heating will be switched
on until the temperature is reached by one of the sensors.
Heating may be switched off because a temperature of the external
sensor is reached even though the air temperature is not reached
(internal sensor).
