The HTM1CF controller is an indoor device designed for sensing or correcting room temperature and relative humidity without aggressive impurities. It is based on the older version HTM1C with OLED display, from which it differs by using TFT display due to lower energy consumption and longer display lifetime. Using the buttons or the overriding system, you can set the correction or the desired temperature and relative humidity value, select up to three of the 48 possible modes, or the overriding system can be used to indicate information about the status, mode and...

The device is equipped with one universal DI and one universal DO with PWM option. The controller electronics is made up of two parts. The display part with the control is located on the PCB inside the housing and the main part with the terminals is located in a box that is inserted into the installation box. Both parts are disassembled and connected by a flat wire. The actual temperature and humidity sensor is located in a metal housing on the front cover of the instrument. Since the sensor is open, it must be protected from dirt, excessive dust or direct exposure to water!
