Plaster walls

My wife and I built a sunroom this year and kind of waffled on whether to put heat in or use it as a 3 season room. We kind of compromised and ended up installing one of the ductless air conditioner/heat pump units. Living in New Hampshire the heat pump unit isn't very effective at temperatures below 20 degrees F, which we knew at the outset. However, and this is my question, if we have the walls plastered, can plaster stand up to the wide swings in temperature without cracking? Without the cooling/heating unit turned on, the temperature extremes could go from -10 F in the winter to +100F in the summer.

The plaster walls in my house have survived since 1939. We all know what kind of heating and cooling to expect in the foothills of the Appalachain Mountains for many of those years. The temperature here rarely drops below +10 F, but 100F is not unusual. Naturally, there is no insulation in the walls. I haven't gotten around to that yet.
