Figure: Example of radiator application

The DRX2 automation station controls electric radiator valves via Triac or

analog outputs, regardless of available I/Os. Single-stage and modulating

electric radiators are supported. Electric radiators, controlled via an analog

output on the DXR2, can receive an enable via a relay or Triac on the DXR2.

A binary overtemperature (open contact) protection can be connected on the

DXR2 for all versions of the electric radiator application. The application

switches off the radiator at device protection priority if overtemperature

protection is enabled.
