Set the Disable or ReEnable value to 220 to have the controller ignore the disable/enable feature entirely.
To enable this feature, an air sensor and humidity sensor must be installed.
The FULL ON Temp is the temperature at which the controller should turn on evaporative cooling continuously. When
the temperature is between the OFF Temp and the FULL ON Temp, the cycle table is used (see below).
COOL PAD LOW GROUP #5 SETTING Z1-S01
FULL ON Temp: 88.0 OFF Temp: 75.0
When the temperature is between the OFF Temp and the FULL ON Temp, the controller scans the on temperature
values input here. It locates the current temperature and uses the ON and OFF timers specified for that temperature.
If Cycle Timers are not set up, the controller simply uses the FULL ON Temp and the OFF Temp.
Cycle one should be the lowest temperature and cycle four should be the highest. The cycle one temperature is
usually slightly higher than the OFF Temp.
Setting the ON and OFF timers to any non-zero value enables their operation. When the ON timer is complete, the
OFF timer starts running. When it is complete, the ON timer starts again. This cycle repeats for as long as the cycle
timer is on.
