5.1.1 Temperature Setting at the Controller
Set the desired temperature. Setting range +20ºC to +55ºC.
To avoid cyclic operation of the compressor, it is imperative that the set switching difference of 5 K is
not changed and does not deviate to a lower value.
5.2 Control by Microcontroller
Version....500
After electrical connection the internal fan turns on and circulates the enclosure air. This helps
assure even temperature distribution within the enclosure. The condenser fan and compressor are
controlled by the microcontroller. The minimum run time is 90 seconds. The switching difference is
5-10 K and is set at the factory. In order to maximize energy efficiency the thermostat should be set
to the highest enclosure temperature as allowed by the electronics.
