Fail Safe Operations

This controller has many fail safe functions built in. There are fail safes that will force on the fans if the air con or dehumidifier fail, others that will stop the CO2 if the door is opened (if intruder alarm fitted) and others that will switch over lights if a bulb fails or switch off lighting if the air-cooled shades overheat.

If CO2 should run out or stop working, the controller will detect this and revert to maximising the intake of ambient CO2. These are in addition to the power-fail light-on sequencing
