3.1. General information

Thank you for purchasing this indoor unit.
The unit is the indoor part of the air to water RRLQ heat pumps. This
unit is designed for wall mounted indoor installation. See
"6.1. Selecting an installation location" on page 12. The unit can be
combined with Rotex fan coil units, floor heating applications, low
temperature radiators and
applications.
Heating/cooling units and heating only units
The unit range consists of two main versions: a heating/cooling
(RKHBX) version and a heating only (RKHBH) version.
Both versions are delivered with an integrated backup heater for
additional heating capacity during low 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 two different power supply specifications.
