FREQUENTLY ASKED QUESTIONS

Q: 

What is the countdown time on a C165

A: 

There are two levels of countdown (aka fresh air purge) on a C165 .

From first switch on if ‘cold’ (more than 41°F from the temperature at which calibrated) = 90 secs .
From first switch on if ‘warm’ (within 41°F of the temperature at which calibrated) = 60 secs
