Colour:
RAL7035 light grey
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 separa- ted by a span that is equivalent to10K. A neutral zone of at least 10K is thus created. Installers charged with the setting and ins- tallation of the device can hence no longer misadjust the switch points or erroneously set them in an overlapping manner. The controller is intended for the installation on a DIN standard rail. The installation set JZ-13 will be required for the installation of the device on a sheet metal wall or on a profiled frame.
