General information
Thank you for purchasing this
AD
indoor unit.
The
AD

reversible air to water Daikin ERHQ heat pumps. These units are
designed for wall mounted indoor installation and used for both
heating and cooling applications. The units can be combined with
Daikinfan coil units, floor heating applications, low temperature
radiators,domestic water heating applications and solar kit for
domestic hot water applications.
Heating/cooling units and heating only units
The
AD
indoor unit range consists of two main
versions: a heating/cooling (EKHBX) version and a heating only
(EKHBH) version.
Both versions are delivered with an integrated backup heater. The
backup heater only serves as a backup in case of malfunctioning of
the outdoor unit or when the unit is operating out of its operation
range. If the unit is operating out of its operation range, the
compressor will stop and the backup heater will function.
