3. Set a low temperature threshold.
The low temperature threshold is the outside temperature below which the dehumidi-
fication 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.
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.

This time setting in seconds is the shortest time permitted for switching between tem-
perature stages. A typical value here would be 60 to 120 seconds. This parameter is
useful in minimizing the cycling of your equipment.

This selection gives you a table with each piece of equipment in the left column and
each stage of heating and cooling across the top. It gives a quick overview of how you've
programmed each piece of equipment. It also gives you the option of programming in a
single location any or all of the equipment for temperature control.

This selection gives you a table with each piece of equipment in the left column and
each humidity stage across the top. It gives a quick overview of how you've pro-
grammed each piece of equipment. It also gives you the option of programming in a
single location any or all of the equipment for humidity control.
4.2.1.1.
When the zones humidity goes below the low humidity setpoint, this engages the hu-
midity or humidification stage.
Equipment programmed at the controller can be activated or de-activated, as desired,
