General information
Thank you for purchasing this
indoor unit.
The
indoor unit is the indoor part of the
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
Daikin fan coil units, floor heating applications, low temperature
radiators and sanitary water heating applications.
Heating/cooling units and heating only units
The
indoor unit range consists of two main
versions: a heating/cooling (EKHBX) version and a heating only
(EKHBH) version.
Both versions can optionally be 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 of the outdoor unit. The backup heater models are
available for a heating capacity of 3, 6 and 9 kW, and – depending on
the heating capacity – for three different power supply specifications.
