ADVANCE HUMIDITY SETTINGS:
To get to the advance Humidity Settings Screen: from home screen, hit OK->3. System Setup->10. Advance Settings-
>1.Advance Humidity Settings.
With this screen you have the option of cycling the
humidification and dehumidification stages.
For example, suppose the zone humidity exceeds the
humidity threshold. Without the cycling option, your
system will remain in the dehumidification stage until
the humidity falls below the dehumidification threshold
by at least 2% RH. In some cases it may be impossible to
get below your humidity threshold. For these
circumstances and for other cases, it would be helpful to
cycle in and out of the humidity control override. This
screen gives you the capability to do so.
The options are:
1. Set the override ON duration in minutes and seconds
2. Set the override OFF duration in minutes and seconds
3. Set a low temperature threshold.
Override On Duration: Is the time for the override to remain active
Override Off Duration: Is the time for override to remain inactive/off
Buttons #1 - #4 can be used to select override on/off. Wheel can be used to change the values.
LowOutTemp: If temperature falls below this value, override will trigger.
Button #5 is used to select low out temp option. Wheel can be used to change the values.
The LowOutTemp threshold is the outside temperature below which the dehumidification stage will revert to its Cold
dehumidification state. For example, you may want to dehumidify but if it’s very cold outside, you may want to turn on the
heat instead of open a vent and turning on a fan.
Cycling Program if no Humidity Sensor is present: This humidity settings option can be useful in other applications even if
you do not have a humidity sensor. For example, you may want to do misting control with a particular output, You can set
up a “software” humidity sensor, a humidity time window and threshold so that the cycling will take place during your
selected time period.
Also, here is a list of videos, so you can program your controller with confidence, and also have an understanding of what
Setpoints are for, Staging of your equipment in Temperature and Humidity Stages, as well as how to Program your
equipment.
