TRD S 25
The electronic thermostat can be used as a heating or cooling thermostat or optionally as a PID two-point
controller. It measures the process variables via a thermocouple. When used as a PID two-point controller,
the controller structures P, I, PD, PI, and PID are possible.
The device type TRD S 25 is available with 1 relay and 1 digital output (DC 0/14 V).
