EXAMPLES FOR USE OF THE DRIVE IN HEATING SYSTEMS
VALVE CONTROL
OPEN/CLOSE:
It is performed with the connection of
the drive on room thermostat thought
a switching contact. The above
example shows our ELTHERM AT8
room thermostat. When the drive is
connected to room thermostat thought
operating contact only, use an external
relay or a drive version built-in relay
module.

CONTROL OF VALVE POSITION:
The control is performed with the connection of the drive to 3-point regulation control unit which
regulates the temperature of heating water with mixing valve in dependance from outer and/of
room temperature (programme ROTOTERM). The left above example shows the regulation of
floor heating with programmable regulation control unit ROTOTERM AT2000. The right example
shows remote heating system. Heating is regulated with programmable control unit ROTOTERM
R2000. There can be used also other ROTOTERM control units from our production range, witch
are mounted on the wall.
In both cases the heating of sanitary water in water heater is separately regulated thought the
probe of the heater. Output from the regulator is controlled by motor driven ball valve EMV110.. of
our production range and it controls also the pump for water heater. Use of EMV prevents thermal
circulation of water thought water heater.
