K+G Wind and Rain Control WRS 2b

Wind and rain control WRS 2b

• In the event of wind / rain, a closing command is sent to SHEV control panels or ventilation control units. Four separate potential-free changeover contacts (output contacts) provide the required signal. The contacts remain active as long as a sensor has responded, but at least for 6 minutes
• Connection of a wind sensor WM or rain sensor RS is required
• Wind and rain sensitivity adjustable
• Selectable functions:

1. - "Reduced wind sensitivity" (to close, equally strong wind must last longer)
2. - "Continuous heating" (the rain sensor is heated continuously)
3. - "Contact programming" (contacts 3 and 4 switch alternatively in case of wind and/or rain)
4. - "Output deactivated" (deactivate all output contacts for service / maintenance purposes)
5. - "Reduced closing time" (the minimum closing time is reduced from 6 to 3 minutes)
6. - "Fault contact" (contact 2 switches in the event of a rain sensor fault)
7. - "Test" (mode for testing the function of sensors and drives)

• Displays for operation I, wind W and rain R
• Plastic housing, light gray (RAL 7035)
