1.1 General information
■ These units are used for both heating and cooling applications.
They can be combined with fan coil units, floor heating
applications, low temperature high efficiency radiators, domestic
hot water tanks (field supply) and solar kits (field supply).
■ A wired user interface is supplied with the unit to control the
installation.
■
The unit is delivered with an integrated backup heater for
additional heating capacity during cold outdoor temperatures. The
backup heater also serves as a backup in case of malfunctioning
and for freeze protection of the outside water piping during winter
time. The capacity of backup heater for different units is listed below.
