The ELEKTRA TDR 4020-PRO Electronic Temperature
Controller is designed for pipe heating systems, including antifrost
protection and maintaining the desired pipeline temperature.
The temperature controller has got two freely
configurable relays, and the TTL port which give the optional
possibility to connect the BusAdapter module with the RS-485
bus or the Unicard with the USB port. The controller cooperates
with BMS systems via ModBus or Televis protocols, or
