SLEEP
- This function when selected will allow the user to determine a “sleep” period. In
cooling the selected temperature will rise to 1
°
above set point in 1/2 hour,
rising to 2
°
in 1 hour, rising again to 4
°
after 2 hours of the SLEEP CYCLE.

DRY
- This function operates to control humidity within a conditioned space. It
measures the difference between set point and the actual room temperature.
An algorithm determines how far above set point the actual room temperature is
to set point temperature and selects periods of water valve operation and low fan
operation. The greater the difference between room temperature and set point
temperature prompts greater run time with less temperature. With less
temperature differences, periods of fan and valve operation are called for in
varying increments as determined by the difference. In this mode (low speed) fan
operation will start 30 seconds after valve has opened and stops 30 seconds after
valve has closed.
