The TCON-CSD/20 is a compact digital thermostat for simple ON/OFF temperature control. The temperature is measured through a temperature sensor and shown on a LCD display. The actual status of the output relay is signaled via a LED. The instrument is commissioned and operated via three soft key push buttons on the unit’s front panel. Through its compact design and robust construction the TCON-CSD/20 allows for simple and space-saving installation.
