The regulation characteristic is of the PID type; the proportional band may be set at the rear of the thermostat by means of a single-rev trimmer in the range ±
The outputs have relays with contacts protected by VDR. The state of the relays is indicated by two LED's on the front. The desired working temperature (set point) may be set by means of a 15-rev knob
on the front panel. The instrument has a Pt100 Platinum temperature sensor (100ohm at 0° C).
With the three-wire connection, the line resistance is automatically compensated up to 5 meters.
