Optional Accessories
Rain Sensor (Included)
The sensor will close the window/skylight when “beading” moisture is
present on the surface of the panel. It will also cause the “Green”
LED on the wall plate to blink (indicating rain is present). Once the
panel is dry, normal operation is regained.
Note:
1. Connect the supplied sensor panel to the Grey & Green terminals on
Block 4 (See Wire Diagram)
2. The window/skylight can be forced to open even when the sensor is “wet”
but the motor will immediately re-close the vent.
Rain Sensor Guidelines:
- Install the sensor with "grid" exposed.
-
Do Not
use rain sensor if the control is being used as a Smoke Vent (See HPI)
- Wire with 22 AWG - 2 conductor shielded, twisted pair 50 ft (15m) Max.
Note: Connect shield to earth ground to reduce interference from lightning.
- Consider prevailing winds when locating the sensor. Keeping away from
obstructions.
- The sensor can be mounted outside (maximum sensitivity) or inside vent
edge (minimum maintenance)
- Maintenance; Regular cleaning of sensor panel with a mild cleaning agent.
Dirt or debris can cause the vent to stay closed even when rain is not
present.
- Do Not route sensor wire through the chain port, damage to wire will result
in erratic operation of motor system.
