An optional hard wired controller for the Elta MORI HR 100, MORI HR 150 and Brookvent Aircycle 100 or 150mm Single Room Heat Recovery fans when user control over the fan’s operation and speed is required instead of the fully automatic alternate flow built in as standard to the fans.
 
The controller allows the user to switch the fan on or off, adjust it’s speed setting and also override the automatic alternate flow operation when required.
