FSL-CONTROL III

Specification text

FSL-CONTROL III is a stand-alone single room control system with a simple timer. Optional expansions, e.g. connection to the BACS with Modbus TCP/RTU, humidity sensors, return temperature sensors, electric valve actuators or pressure-independent control valves, are part of the supply package, but will have to replace the standard components in the following description. A room temperature signal is also required. Various room control panels and sensors are available to provide this signal. Suitable optional equipment is described in the appendix to the following standard equipment for stand-alone operation. We recommend commissioning by our technical service. You will find related text modules below.

TROX control module FSL-CONTROL III (order code ... -C3-MA ...):

Single room controller that can be mounted on a DIN mounting rail in the ventilation unit or in a separate control equipment box
