Description
This SHEVS Control Centre allows the configuration of one SHE group and one ventilation group. 24 VDC actuators can be controlled with a total output current of 4 A.
In addition to the DIP switches for setting the desired functions, the control centre has an internal service display that shows operating states as well as alarm and fault messages. Furthermore, coloured LEDs indicate active travel commands and other operating modes. The status of the SHEV system can thus be checked at the control centre in a user-friendly way.
In addition to detectors, ventilation buttons with position indicators and an external WRS wind and rain control system can be connected. As an alternative, the WRM option is available as an internal wind and rain control system.
Please note the approved accumulators for use in our RWA control centres and control systems.
