Data Sheet for Product

Application
The HRC3.1 room controller integrates temperature control, energy management,
access control and the management of a hotel room, at room level.
For operation, room operator units, access card readers and access card holders with
bus connection and switch e.g. to turn on the lights are used.
Functions
The functions are determined by the downloadable application software. The room
controllers are delivered with the standard application (the basic features are described
in this data sheet).
In special cases, the standard application can be overwritten with a customized
application software. A commissioning and service tool is available for this purpose.
The following options can be implemented with fan-coil units: Temperature control
• 4-pipe heating/cooling with 3-position or PWM output
• 2-pipe heating/cooling with 3-position or PWM output with changeover
• 2-pipe system with internal electric heating, 2-position or PWM output, and cooling
with 3-position or PWM output
• 2-pipe system with external electric heating, 2-position or PWM output, and cooling
with 3-position or PWM output
• 4-pipe heating via external radiator and cooling with 3-position or PWM output
• Auxiliary heating in bathroom, additional radiator or underfloor heating with
2-position, 3-position or PWM output
Room temperature setpoints:
•
Centrally programmable room comfort temperature setpoint
•
Individual setpoint adjustment of room comfort room temperature setpoint in guest's
room
•
Precomfort setpoints when guest is absent
•
Economy setpoints for free rooms (i.e. from which guests have checked out)
• Remote room temperature setpoint adjustment in rooms unoccupied for long periods
Energy-saving features:
• Energy management for individual room control system and lighting
