What is the countdown time on a KANE456?
There are three levels of countdown (aka fresh air purge) on a KANE456
From first switch on if ‘cold’ (more than 5℃ from the temperature at which calibrated) = 90 secs.
From first switch on if ‘warm’ (within 5℃ of the temperature at which calibrated) = 60 secs.
If switched on within 10 minutes of last switch off and had been on for at least 10 mins and is still ‘warm’ = 30 secs.
