4.3 Temperature control
4.3.1 Temperature control method setting
The temperature control method can be set by parameters.
4.3.2 ON/OFF control
The ON or OFF state is controlled by comparing PV (display value) and SV (set
value).
Hysteresis value setting
When the ON/OFF control output is used, the ON hysteresis and OFF deviation
values can be set.
When the hysteresis value is set too low, it may cause frequent movements and cause
interference (noise, vibration, etc.). In order to reduce interference, the appropriate ON and
OFF offsets are set according to the heating and cooling capacity and thermal
characteristics, the response frequency between the controller and the sensor, the
installation environment and other relevant factors.
