Microprocessor Control Board
–
Random start timer prevents multiple units from
simultaneous start-ups after power outage.
–
Fan purge — fan remains on for 60 seconds after
heat/cool call is satisfied
–
Anti-short-cycle compressor protection prevents
compressor from rapid cycling
–
Freeze protection — prevents evaporator coil
freeze up, improving compressor reliability
–
Low ambient lockout prevents compressor
operation in outdoor temperatures less than 40°F
(4.4°C) Heating, 25°F Cooling.
–
Test operation — all timers are temporarily
suppressed to allow ease of testing or
troubleshooting
–
Control board LED provides self-diagnostic
troubleshooting codes. See Sequence of
