MS-Cable (master-slave cable)
Control panel includes also a number of special features such as diagnostics function, room brightness measurement and re-programmability. The power supply and data transfer between cabin unit and control panel is carried out via interconnection cable.Temperature range is software adjustable between 10 and 30°C degrees.
When passenger demands for a lower temperature, the damper opens the cold air duct in order to increase of flow of cool air towards to maximum setpoint. Simultaneously the damper closes the warm air duct. When the required temperature in the cabin is achieved, the damper references are held until the temperature demand changes. In a heating mode, the operation is reserved.
Airflow is kept in pre-set level in any condition. When passenger demands for a lower temperature by using control panel, the damper opens the cold air duct in order to increase of flow of cool air. Simultaneously the damper closes the warm air duct. When the required temperature in the cabin is achieved, the damper references are held until the temperature demand changes. In a heating mode, the operation is reserved.
* ductwork pressure 200 – 1000 Pa (optimal)
When comparing airlow measurements between cabin unit and other device, cabin unit’s airflow regulation dead-band has to be taken into account (± 10m3/h).

Projects requirements and possibilities should be taken into account when designing the installation. For more information on the possibilities contact Halton Marine sales office.
Main principles in cabin unit installation:
1. Fix cabin unit above false ceiling using thread bar (as seen on picture) or frame installation
2. Connect power supply and IC cable to the unit. (cable installation should be done before this phase, see Interconnection Cable Mounting Instructions). As standard cabin unit has Ensto NAC 31 plug for the power supply (counterpart NAC 32 not include).
3. Connect supply air ducts to cabin unit inlets.
4. Close maintenance / installation hatch.
5. Connect and assemble diffuser to the cabin unit outlet.
1. Install LRC-1 CP unit back plate to the provided leveled place on the wall.
2. Fasten 3 screws (DIN 7981 or similar, Ø 3 mm, max. head height 3 mm ) to fix CP unit to its place.
3. Connect LRC-1 interconnection cable to the interconnection connector. Max. allowed tractive force is 30 N.
4. Install LRC-1 CP unit front plate to the back plate
5. Fasten the screw in the bottom carefully. Max. Torque 0,3 Nm.
The LRC-1 CP unit should be positioned on the wall inside the room it will regulate. It is advised to avoid direct sunlight or position near heating/cooling source object
Interconnection cable comes prefabricated with plugs on both sides. To install, draw it through the provided tube from Cabin unit to CP unit (the plug on CP unit is small enough to allow drawing through Ø 16 mm tubes). Max. allowed tractive force is 30 N. On the CP side, in the room, leave approximately 8 cm of the cable (the wires) outside the tube. The near end of the tube (CP-unit side) must be blocked (e.g. foam) to prevent condensation and thermal transfers reaching CP unit.
A required safety distance as illustrated must be taken into account when installing the cabin unit. Airflow measurement accuracy cannot be guaranteed if safety distances are not taken into account.
All parameters can be preset at the factory according to order. During commissioning all parameters can be modified wirelessly with portable device using LRC manager software.
Halton also provides supervision and commissioning services for the projects.
