Control cabinet thermostats – Heating / Cooling electronic, for the triggering of Peltier elements and fans, 24 VDC

This temperature controller has been specially devised for the triggering of Peltier modules and fans that are usually applied in connection with the conditioning of the air in switch cabinets.
The KTRRN is equipped with two control ranges, i.e. one each for the function “heating” and “cooling”. The selection of the “heating” switch point takes place in the lower section of the setting range, while the one of the “cooling” switch point is effected in the upper section of the range. The setting ranges are separated by a span that is equivalent to10K. A neutral zone of at least 10K is thus created.
