CRC Function Selector – Get started quickly

Find the right function for your application and configure easily via DIP switches

Quick installation with pre-programmed functions

The controllers in Calectro’s CR family come with 15 preset functions, designed to meet common needs in ventilation, heating, and cooling. To make selecting the right function easy, we have developed this function selector.

  1. Filter and select the function that best suits your application.
  2. Click on DIP switch setting and set DIP 2:1–4 to the correct position.
  3. Your CRC controller is now ready to use!

How does it work?

Analog output 1 (0–10V) is affected by the measured values of CO2, temperature, and humidity, and the output voltage is controlled by the highest measurement value. In addition, you can choose to control heating, extra cooling, or air quality (CO2).
If you want to use CRC as a pure transmitter, that is also possible. If the preset settings do not meet your needs, they can be easily adjusted or completely reprogrammed via Modbus – for full flexibility in your control solution.
