+Cold temperatures around freezing also can be problematic. Several components are not rated to operate at freezing temps. The DM is temperature sensitive with a 5° C lower limit. Do not open unless it is above freezing and keep an eye on the temps if they are still dropping.
+  * Do not open if T_out is near freezing and trending downward.
