Access Configuration Manual

As an alternative or complement to analog control, heating and cooling can be activated in steps. The internal signal is then used to activate digital outputs for controlling the heater or cooler.

Two step controllers with up to four step outputs can be configured.

This function is used in most cases for controlling electric heaters directly by giving power supply to their different heating rods (used for heaters without their own temperature control only).

There are two possible modes: Sequential control and Binary control.

Binary control:

• Control of temperature is more exactly than Sequential control.
• There are different loads on e-heater needed
• There are usually fewer outputs of controller used

Sequential control:

• Control of temperature is not so exactly like in binary control
• It is possible to have the same load on each output
