CONTROL TYPES
The Thyro-PX power controller has six control types effective as underlying controls.
Mains voltage variations and load changes are directly, and therefore quickly,
adjusted by bypassing the slow temperature control system.
Before commissioning the power controller and selecting a control type, you should
be familiar with the application and with the operating characteristics of the load.
Controlled Value
The controlled value effect on the load is proportional to the total setpoint, depending
on the control type, as shown in the following table.
