CONTROL CABINET THERMOSTATS ELECTRONIC, FOR PELTIER MODULE – HEATING / COOLING
TECHNICAL DATA
APPLICATION
Housing colour: Housing material: Supply voltage: Switching capacity:
light grey RAL7035
This controller was specially designed for controlling Peltier modules that have fans for the purpose of air conditioning control cabinets. The KTRRN features two control ranges for heating and cooling. The switching point for heating is selected in the lower setting range, and the switching point for cooling is selected in the upper setting range. The setting ranges are divided into ranges of 10 K. There - fore a neutral zone of at least 10 K is always given, and incorrect switching point settings / switching point overlaps created by the installer are avoided. The controller is installed on a DIN standard rail. Mounting set JZ-13 is used when mounting on a sheet metal wall or profile frame.
