Room drying with room temperature monitoring and
“comfort ventilation” for a wine cellar
The humidity should be lowered in a wine cellar. In order to ensure room air quality to a large extent,
the fan is switched on for one time window regardless of the room temperature (“comfort ventilation”)
even on days with humid exterior air.
The fan for room drying runs if:
- the absolute exterior humidity is lower than the interior one and
- the relative interior humidity is higher than e.g. 60% and
- the room temperature is above the required temperature (example: 10C) and
- the optional interval switch ("Timer") is active.
The fan for “comfort ventilation” runs
- daily according to the time window regardless of other settings (example: 10:00 to 10:30 a.m.),
up to three time windows can be set
Recommended settings for UVR61-3
Start threshold for inside absolute
humidity in g/m³ (display: °C)
Start threshold for relative humidity in
% (display: °C)
Start threshold for room temperature in
°C
Minimum differential, absolute humidity
outside - inside
Set diff 2 and diff 3 to "unused" (setting
over 98 °C, display: --)
Within this time window, the fan runs
independently of the humidity and
temperature conditions.
The fan is switched ON and OFF
alternately (ON and OFF time in
minutes).
With time window setting OPO 12, “comfort ventilation” takes place only if the room temperature has
exceeded the temperature threshold.
