HVAC&R Application

The universal controllers are intended for Heating, Ventilating, Air-Conditioning and Refrigeration in comfort control plants. It can be mounted in a control panel or in the housing on ducts, walls and in plant rooms.

Measurement and control of temperature, relative humidity, absolute humidity, enthalpy, pressure differential, volumetric airflow and indoor air quality. The input scale can be set from 0 units to 1,000 units. The start and end points of output voltage can be any value between 0 V DC to 10 V DC.
