INTRODUCTION
General information
Thank you for purchasing this Rotex outdoor monoblock unit.
These units are used for both heating and cooling applications. The
units can be combined with Rotex fan coil units, floor heating
applications, low temperature radiators and domestic water heating
applications.
Heating/cooling units and heating only units
The Rotex outdoor monoblock unit range consists of two main
versions: a heating/cooling (RB) version and a heating only (RD)
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 unit and for freeze protection of the outside waterpiping during
winter time. The backup heater factory set capacity is 6 kW, however,
depending on the installation, the installer can limit the backup heater
capacity to 3 kW/2 kW. The backup heater capacity decision is a
mode based on the equilibriumtemperature, see scheme below.
