Cruisair Heating Question

[pkrawetzky]

this is my first reverse cycle heating unit. It's a 48,000BTU split system and has a 2 dial control with a high/low fan switch (not dial).

I'm now in heating mode. What I noticed is the unit will switch to AC mode once the heat temp is reached before turning off the compressor. Is this normal? I thought there was a 3.5 degree differential between the heat and AC. I had the triac replaced back in August because it went bad (compressor would not shut off when the dial was in the off position). Been running just fine in cooling mode but I'm worried the system will be damaged by not shutting off when the heat temp is reached.

Thanks in advance.
