During the AHU validation, it is necessary to record the temperature and humidity readings in records for the respective areas ?

yes it is mandatory. It should be record for 3 consecutive working days and 3 reading per a day.

we have been monitoring temp.& RH on daily once.
My question is, during AHU validation, is it necessary to record the values or under AHU validation to be write?
