Controller for cooling applications
Order number 900312.001
As of: 26.11.2015, Software V2.0
Wiring diagram
Product description
The cooling controller ST710-KPLVR.112S has an interface for ST-Bus/MOD-Bus.
Besides PTC, the three sensor entrances are applicable also for Pt1000 resistance, which clearly
increases the measuring range. The functions of the switching input and the four relay exits can be
freely selected, whereas various applications with only one controller are possible. The controller,
for example, can operate with two coolers if the evaporator sensor is parametered as sensor for a
second refrigerating chamber.
Sensor: PTC
Range: -50...150 °C
Front size: 84mm x 42mm
Panel cut-out: 67.5mm x 31.5mm
Tightness: front IP65
Connector: plug and socket
Special software: ST-Bus / MOD-Bus switchable (see parameter L10)
Order no.: 900312.001
