Humidity Treatment
Humidity treatment forces an increase in ventilation level when the humidity is too high. It holds the
increase for ‘Duration Seconds’, and checks back after ‘Interval Minutes’ for another increase. After the
duration, the ventilation level comes back down automatically.
1. In
Install > Analog Sensors
(refer to Analog Sensors, page 109), designate up one or two
sensors as indoor humidity sensors (outdoor sensor is for information only). When using more than
one sensor, Farm Premium begins treatments based on the average.
2. If required, go to
Service > Humidity Calibration
, and calibrate the sensors (refer to Humidity
Calibration, page 95).
3. In
Control > Humidity Treatment
set the parameters as required.
o
Day: Growth day. Can set multiple programs for same day (Maximum number of
programs: 20)
o
Humidity: Humidity at which to begin treatment
o
Delay Minute: Amount of time the controller pauses before ventilating
o
Duration Seconds: Number of seconds the controller maintains the increased level of
ventilation
4. Set the Humidity Sensor Alarm (page 72).
