Winter Setting
In the past we have set out thermostat at 48 to 50 degrees. I turned off the water but didn't drain the pipes. We have an unfinished dirt floor crawlspace with a poured concrete foundation. To date, nary a problem. We came up a couple times in the winter to check things out and if we decided to stay overnight, we simply cranked up the heat and turned the water on.
That was years past. This winter because of the cost of heating oil, we will, for the first time completely winterize and close the place up.
I doubt that you will have any issues if you set the temp at 45 to 50.
