Removed thermostat programs as there was an issue with the system randomly turning on. Found that the main thermostat has been replaced to a Honeywell t stat and now the slave thermostat in the master bedroom no longer functions as it is missing the master thermostat for communication. Found water in the secondary drain pan and noticed the primary drain line to be sloping uphill and this was corrected. Tested system cooling and system functioned throughout all test. There is no safety switch as the secondary is piped out doors. Walked customer through thermostat functions and they were aware of the functions. Possible intermittent issue that is not showing at the moment. Also checked refrigerant charge for low cut out issues and found that was within tolerances.
