During Frost protection, the display will read Cool Down Protection.
NOTE!
In order to enable setting up, this function is not
available for 60min after energizing the ventilation unit.

the rooms. The installation of a Defrost heater in the Fresh air duct is recommended to prevent ice
build-up.
6.5.3 Safety cut-out function
(See also Section 4.5.8)
The Smoke Detector terminal on the Main Connector PCB is used to connect to an external smoke detector.
Connect the volt free output from the smoke detector control to the “Smoke Detector” terminals.
If an external smoke detector is not fitted then :
•
Put a shorting link across the Smoke Detector terminals on the Main Connector PCB. (See Section 4.5.1).
If the Smoke Detector terminals are open, display reads “SMOKE ALARM. UNIT IS OFF” and unit remains OFF.
•
When the Smoke Detector contacts are re-closed the display reads “SMOKE ALARM OVER. Press OK”
Unit returns to Normal and is “Off”. Select “Automatic” to start the unit again.
The ventilation unit will switch off immediately when the “Smoke Detector” terminals are opened.
