(*) The unit can not operate in cold weather conditions below -15
℃
. If
it is necessary to operate, an external auxiliary heat source must
be added as a backup heater. the backup heater also serves as a
backup in case of malfunctioning of the unit and for freeze
protection of the outside water piping during winter time.
These models have an antifreeze function that allows the use of
heat pumps to keep the water system free from freezing under all
conditions. If there is an accident or intentional power outage, it is
recommended to use ethylene glycol.
