During the winter and while being away from the boat
, I want to set my Cruisair
SMXir to start heating
only if the air temperature drops to a level where there is risk of freezing, eg. 40°F / 5°C.
However the system does not seem to allow a set-point below 60°F / 15°C.
Is there a way the unit can be re-programmed to allow a lower set-point?
Any other ideas or suggestions?
