The HARS-C27 room controller integrates temperature control, energy management,
access control, light control, room safe control and the management of a hotel room, at
room level.
For operation, use is made of room operating unit, card reader, card holder, light
operating unit and a connection to the bus and power supply.
Functions
The room controllers are delivered with the standard application if not defined
specifically (the basic features are described in this data sheet).
The functions are determined according to standard application functions (if not
specified otherwise).
In special cases, the standard application may be overwritten with a definitive
customized application software. A commissioning and service tool is available for this
purpose.
• 4-pipe heating/cooling with 3-position or PWM valves output

Mechanical design
The HARS-C27 controller consists of a housing base, a housing cover and a printed
circuit board with connection terminals.
The controller also has a tool socket.
Terminal covers
STOP Caution
Owing to the intrinsic heat generated by the
controller, terminal covers must not be used,
as this can cause overheating.
For the same reason, adequate air circulation
must be provided in the location where the
controller is installed.
Building Technologies 01.10.2009
To prevent accidental physical contact with relay connections carrying voltages in
excess of the SELV voltage range (Ueff > 42), the device must be fitted in a housing
(preferably a control panel). This enclosure must be accessible only by use of a key or
tool.
Alternatively, a commercially available contact guard can be used.
All terminals are plug-in type to ensure easier maintenance and commissioning.
To avoid incorrect wiring, terminals which can be connected to AC 230 V (supply and
relay outputs) are physically segregated from the other terminals. They are arranged so
that, under normal circumstances, all incoming and outgoing cables can be connected
without crossing.
• If the management system or communication link fails, this will not affect local
operation
• External fuses are required for load operation power supply inputs
• The controller comes with a self-resetting thermal fuse to prevent overload damage.
Disposal
The device includes electrical and electronic components and must not be disposed of
as domestic waste.

Engineering notes
• 230VAC is required for the room controller power supply. This power supply should
be provided for all HARS-Cxx controllers through UPS or aggregate power supply
source
• Additional 230VAC is required for loads control power supply.
• All HARS-Cxx controllers are connected together via RS485 bus. A RS485/RS232
converter is installed on a central place between room controllers and PC. No more
than 128 controllers can be connected on the same BUS line. In practice BUS line is
divided onto logical areas (i.e. floors, dilatations, groups of rooms, etc.). Maximum
cable length for one BUS line is 1000 m.
• The room controller must be installed in a control panel or covered enclosure, which
can only be opened with a key or tool. Adequate air circulation must be ensured.
• The relevant technical, and health and safety regulations must be observed,
including local electricity company regulations applicable to connection of devices to
the electricity network.
• The management level PCs must be protected with a UPS (uninterruptible power
supply).

• A mechanical safety lock must be provided to allow the doors to be opened from the
outside in extreme emergencies.
The sizing and fuse protection of the power supply cables depends on the total load
and on local regulations.
• Relay outputs allow switching of loads up to AC 250 V, 6 A. The cable dimensions
depend on the connected load and the local installation regulations. The circuits
must be externally fused (≤ 6 A), as there are no internal fuses.
• The output loads control power supply input X7 should be connected to mains
voltage 230 V if not otherwise specified.
STOP Caution
• Fan coils must not be connected in parallel (use cut-off relays).
Mounting instructions
The room controller can be mounted in any orientation, as follows:
Rail mounting
snap-mounting on DIN rails, type EN 60175
(can be released with a screwdriver).
• The HARS-C27 room controller is installed in the corridor with other installed
devices, behind the plasterboard.
• There must be a means of dissipating the heat generated during operation.
Adequate air circulation must be ensured.
• Subject to certain conditions, the HARS-C27 room controller can be installed in
suspended ceilings. Potential noise problems caused by the switching of relays
should be resolved in a sample room.
• As installation is the same for all types of room (e.g. single rooms or suites), it is
recommended that a sample room should be set up for each room type, in
cooperation with the electrical installer.
• Ensure the room controller is accessible for commissioning and service work.
• The card holder is intended for fixed installation in a dry, enclosed space.
• Commissioning must be carried out by trained personnel only
STOP Caution
AC 230 V
Building Technologies 01.10.2009
• LiYCY twisted pair type cable with 2 twisted pair for connection of the RS232/RS485
converter to all room controllers (includes 2 spare wires)
The following room devices can be connected to the room controller:
- card reader
- card holder
- card reader
- card holder
STOP Caution
Adequate EMC precautions must be taken when installing the equipment.
The room bus and room peripherals cables must not be routed in the same
conduit as high voltage conductors.
Commissioning
• During commissioning, the room controller address has to be set by using room
operator unit connected to its socket X11.
• The controller must be connected to the supply voltage for this purpose.
• In the case of customer-specific applications, the customized application software
must be downloaded from a service tool to service socket K1.
• The room controllers are already loaded with the standard application on delivery.
It is then only necessary to adjust the parameters with the commissioning software.
