First post here and looking for help. I had installed a Climette (ICP) 12000btu mini-split heat pump (R410A). All works well however I have a concern about low outdoor temperature, I live in an area where outdoor temperatures can easily reach -20f, I do not believe the heat pump will produce heat at that low temperature and all the literature and research I have done does not point to any type of low temperature cut off for the unit. I am concerned about possible damage to the unit at low outdoor temperature and the fact it would run for nothing wasting electricity. Are my concerns valid, are there kits to cut out the unit, would you cut the main power or a control wire. Any help would be appreciated.
