Lennox air conditioner
I have a Lennox ELITE series XP16-24-230-04 heat pump, CBX27UH-030-230-6-02 Air Handler and a Honeywell Vision PRO TH8000 thermostat.
The problem is that at various time the units will go into a heat mode (uncontrolled) when the thermstat is set for cooling.
I have been able (sometimes) to get back to into a cooling mode by operation of the circuit breaker thus probably reseting the units. At present this operation has not been successful.
Can you provide me some guidance?
