System Supply/ Return Temperature Control

Depending on the expected system supply temperature, the P-band (SST-06), the I-time (SST-07) and the calculated system supply temperature setpoint the internal control signal varies from 0…100% as shown in the next figure.

Fig. 5.   Internal control signal

This internal control signal is used for switching the next stage of a heat generator.
