Note: The thermostat will follow an auto-calibration process the first time Low Cool runs for 3 consecutive hours and High Cool runs for 3 consecutive hours during normal operation. Low Cool and High Cool could run at different days or with an OFF period between. If booth speeds run consecutively Low Cool must be first.
Note: If the swamp cooler system is replaced it is highly recommended to reset the thermostat to factory default values to perform a new auto-calibration the process as follows:
