This unit
The Rotex indoor unit is the indoor part of the reversible air to water
Rotex RRHQ 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 Rotex fan coil units, floor heating,
low temperature radiators and the Rotex domestic hot water tanks.
The Rotex indoor 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 heaters are available in different
capacities.
Options
Domestic hot water tank option
An optional RKHWE 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 different sizes. For more
information about the domestic hot water tank, refer to the installation
manual of the domestic hot water tank.
Remote alarm kit option
For information concerning the EKRP1HB remote alarm, refer to the
installation manual of that kit.
