Relative= relative value setting related to Ventilation set
(Settings>Climate see par. C.1).

setting the cooling control will be on.
This setting is either an absolute or a relative setting depending upon

Timing band of Cooling.
To calibrate the %RH reading (when using the psycrometric kit):
1. Remove the wet sock from the wet temperature probe.
2. Allow the wet temperature probe to dry for 10 mins.
3. Adjust the above setting to make the wet bulb temperature
match that of the dry bulb (Ventilation 1 temperature probe see
par. F.6).
Check periodically the sock installed on the sensor has not been
clogged by calcium carbonate scale. If so, remove it then clean
or replace it.
