Day-to-day natural ventilation
On activation of a thermostat on a single floor, both the dampers on the affected floor will open. One set of fans will extract on trickle mode and the other shaft will provide fresh inlet air for the system. The vent at the head of the stair will also partly open.
If the rain sensor is activated this will override and close the roof vent.
If more than one thermostat operates, the dampers on the affected floors will open and be balanced to provide an equal air flow on each floor.
Smoke detection in any zone will override the natural ventilation system and smoke extract will take priority.
