Halton HMM is a manually operated cabin unit for single duct applications. Airflow is controlled via an adjusting knob installed on the diffuser. The control mechanism has mechanical limits for minimum and maximum airflows. These limits can be easily set during commissioning. HMM is recommended to be used in conjunction with Halton’s diffusers, as the mechanism has to be fixed to the diffuser’s structure. The airflow is adjusted with diffuser knob. The HMM cabin unit can be supplied with reheater – controlled by a control panel.

Airflow is controlled via an adjustment knob between the preset limits.

Models with reheater

When passenger demands for warmer temperature by using control panel, the controller activates the electric reheater inside the cabin unit. When the required temperature in the cabin is achieved, the reference is held until the temperature demand changes.
Mechanical maximum and minimum limits are set during commissioning.

Cabin unit mounting instruction

Projects requirements and possibilities should be taken into account when designing the installation. For more information on the possibilities contact Halton Marine.

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.

Control Panel mounting instruction

1. Install LRC-1 CP unit back plate to the provided leveled place on the wall.
2. Fasten 3 screws (DIN 7981 or similar, Φ3mm, 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 30N.
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 mounting instructions

Interconnection cable comes prefabricated with plugs on both sides. To ins tall, draw it through the provided tube from Cabin unit to CP unit (the plug on CP unit is small enough to allow drawing through Φ16mm tubes). Max. allowed tractive force is 30N. 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.

Safety distances

A required safety distance as illustrated must be taken into account when installing the cabin unit.

The supply flow rate is determined by using the measurement probes and manometer.
The diffuser front plate are removed and tubes are passed through the diffuser. Measure the differential pressure with a manometer. The flow rate is calculated using the formula below.

qv = airflow (m³/h)
k  = k factor
∆p_M =   measured pressure (Pa)

K-factors table

Adjust the minimum airflow rate by rotating the D-shape bar until the desired setting is achieved.
Move the minimum airflow mechanical limiter against the stand and tighten socket cap screw.
Adjust the maximum airflow rate by rotating the D-shape bar until desired setting is achieved.
Move the maximum airflow mechanical limiter against the stand and tighten socket cap screw.

All parameters can be preset at the factory according to order. During commissioning all parameters can be modified wirelessly with a PDA handheld device using LRC manager software.

Halton also provides supervision and commissioning services for the projects.
