Have you set your OpenSprinkler to use weather adjustment? It’s not turned on by default. You can go to Edit Options -> Weather and Sensors and select Zimmerman algorithm (for which you will need to provide a Wunderground API key). The algorithms takes temperature into account and I am pretty sure that at 32 degree it should return a 0% water level effectively preventing any program from running.
