General information
Thank you for purchasing this indoor unit.
The unit is the indoor part of the air to water RRHQ or RRLQ heat
pumps. These units are designed for wall mounted indoor installation.
The units can be combined with Rotex fan coil units, floor heating
applications, low temperature radiators and Rotex domestic water
heating 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 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 two different power supply specifications.
Domestic hot water tank (option)
An optional RKHW* domestic hot water tank with integrated 3 kW
electrical booster heater can be connected to the indoor unit. The
domestic hot water tank is available in one size only: 300 litre. Refer
to the domestic hot water tank installation manual for further details.
Remote thermostat kit (option)
An optional room thermostat RKRTW, RKRTWA, or RKRTR can be
connected to the indoor unit. Refer to the operation manual of the
room thermostat for more information.
