1. A control system for an air conditioning or refrigeration unit, comprising:
- a control device housing;
a main processor provided inside the control device housing controlling at least one of a temperature, a fan, and a defrosting procedure of the air conditioning or refrigeration unit in dependence on respectively prevailing input values, andcontact points provided inside the control device housing for a coprocessor separate from the main processor, the contact points being associated with respective coprocessor input and output signals, with at least one contact point being provided for coprocessor input from at least one of temperature sensors and pressure sensors of a coolant circuit and one contact point being provided for a coprocessor output connected to an electronic expansion valve provided in the coolant circuit.

Abstract
The invention relates to a control unit for a refrigeration or air conditioning device, comprising a main processor that is situated in a housing and that controls the temperature, fan and/or the defrosting process of a refrigeration or air conditioning device. Contact points for a co-processor, which is separate from the main processor and is suitable for controlling an electronic expansion valve, are located in said housing.
