By the term "reversible a/c", Im guessing you mean a heat pump. Im also guessing you wish to provide freeze protection but no comfort heating to save utility cost. If so, here is your answer: Thermostats for environmental heating and cooling do not operate at that cold temperature (32F) because they are designed for comfort heating temperature ranges IE: 55F-85F. It is possible to install a thermostat (designed for a different application which operates in the colder range specified) which could break the "hot" wire to your existing stat and effectively control 1 stat with another but this is a very non-standard situation.
This is more than a casual wiring project. The services of reputable HVAC company should be sought to perform this work if you choose to do it. If improperly wired, major damage could result to the control ciruit of the system which can be very costly to repair/replace. Also, the cost of this work may be more than the utility savings depending on your locale so the cost effectiveness is questionable.

I do not know what a reversible A.C. is but most thermostats only go down to about 55 degrees although I am sure you could get one. If you are thinking of going out of town, I would turn the water off at the main and set the thermo. at 55, let the Police know and you are in good shape. Have a nice day and Merry Christmas everyone.

I have never heard of the term "reversible air conditioning".. but if it is a regular air conditioning.. YES.. it can be set to come on at any temperature that you want.

I think you are talking about a heat pump which is an A/C unit that can be run in reverse to produce heat, instead of cold. They only work above 32 degrees, below that, secondary heat will kick on (typacly electric coil).

Are you refering to a HEAT-PUMP? Heat pumps provide central air in the summer months and then heat in the colder weather. They normally have a Thermostat that lets the unit know when to switch to the heat side. The T-Stats are located outside.
I have one and in the winter when the outside temperature is 34 degrees or warmer the heat pump provides HEAT. When the temperture drops under 34 degrees, it automataically switches to my natural gas furnace.

It can be done quirte easily with the older mercury switch style thermostats. Otherwise you'll have to invest in some additional hardware.
