General information
Thank you for purchasing this indoor unit.
The unit is the indoor part of the air to water ERHQ or ERLQ heat
pumps. These units are designed for wall mounted indoor installation.
See
"Selecting an installation location" on page 12
. The units can be
combined with Daikin fan coil units, floor heating applications, low
temperature radiators, Daikin domestic water heating applications
and Daikin solar kit for domestic hot water applications.
Heating/cooling units and heating only units
The 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 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.
