Operation and parameter setting by means of integral web server

① Stage

Each decentralised ventilation unit has its own controller. The controller controls all functions that are necessary for operation, e.g. providing the control signal for fans and actuators. With dedicated software and hardware the controller can be configured as a master controller; one master controller is required for each room. Additional inputs and interfaces allow for the connection of components that are required for room control. The RTC interface on the master PCB allows for adding a timer; the Modbus-RTU, Modbus/TCP, BACnet/MS/TP or BACnet/IP interface allows for establishing a connection to BACS (by others). Also, TROX X-TAIRMINAL is a powerful visualisation tool.

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.
