C) Others

The controller board comes with other option.

i) Unoccupied Mode If the dry contact is closed, the Unoccupied mode is activated and vice versa. When Timer On is active,

system goes back to Occupied mode.

The dry contact connection points can be connected parallel with other fan coil unit (FCU) boards. If the

dry contact is closed, Unoccupied mode will be activated on all fan coil units that are connected parallel as

shown in gure below.

ii) Anti Freeze Mode Anti Freeze operation has the highest priority among all unit operation. Anti Freeze operation will be activated

only if dry contact is closed and vice versa.

iii) Window Open Mode The dry contact connection points can be connected in parallel with other fan coil unit (FCU) boards. If the

dry contact is closed, Window open mode will be activated on all the fan coil units which are connected in

parallel as shown in gure below.

iv) Load Shedding The dry contact connection points can be connected in parallel with other fan coil unit (FCU) boards. If the

dry contact is closed, Load shedding mode will be activated on all the fan coil units which are connected in

parallel as shown in gure below.

Global Unoccupied, Global Window Open and Global Load Shedding operation could also be activated via the network communication bus line by master controller with or without the above connection.

NOTE : i) Auto Fan Mode is only applicable in Model 3 only. ( Cooling only with Boiler) ii) Fan mode is not available in valveless control. iii) Wired handset (Netware and SLM) has an indoor room sensor. Avoid locating the wired handset at isolated

places where room temperature reading will be inaccurate.

Water Piping Connection

The indoor unit is equipped with water outlet and inlet bare connection. There is an air-vent for air purging that

is tted at the outlet water header.

3 ways solenoid valve is required for cycling off or bypass the chilled water.

Black steel pipe, polyethrene pipe, PVC pipe and copper tube recommended in eld installation.

All types of piping and connection must be insulated by polyurethane (ARMAFLEX type or equivalent) to avoid condensation.

Do not use contaminated or damaged pipe and tting for installation.

Some main tting components are needed in the system to enhance the capacity and ease of service, such as gate valve, balancing valve, 2 ways or 3 ways solenoid valve, lter, strainer etc.

Preliminary Site Survey

Electrical supply and installation is to conform to LOCAL AUTHORITY’s (e.g. National Electricity Board) CODES and REGULATIONS.

Voltage supply uctuation must not exceed ± 10% of rated voltage. Electricity supply lines must be independent of welding transformers which can cause supply uctuation.

Ensure that the location is convenient for wiring and piping.

Mounting

For ceiling mounted models, locate a position where piping and ducting work can be kept to a minimum. Ensure that overhead supports are strong enough to hold the unit’s weight. Position hanger rods and check for alignment with the unit. Check that hangers are secure and that the base of fan coil unit is level in two horizontal positions.

Piping

Drain and water piping must be accurately connected.

Please refer to “Specication Sheet” for piping sizes.

MFCU_(ii)

Application Information

14

Piping Support

All water mains must be adequately supported to carry the necessary weight involved, provisions must be made by the installing contractor to allow for adequate free movement of all vertical and horizontal risers and run outs. Due to the fact that cold water will be circulated through the water mains, a sizeable movement of the water mains can be expected due to contraction. If for example, the piping is rigidly supported with no provision for

movement, it is very possible that the tubing of tting may be broken causing water leakage in the conditioned

spaces throughout the building.

Coil Venting

Each standard basic unit coil is equipped with a manually operated air vent which is installed at the end of a small copper line leading into the highest point of the coil. By means of this valve, air may be vented manually,

from the coil to keep it operating at full capacity. When water is rst introduced into a coil, air is sometimes

trapped in the coil tubing. This trapped air will reduce cooling capacity and create “Bubbling” or “Clanking” noise

within the units. To release air trapped in the coil, press the air vent head to allow air to ow out of the air vent

opening. Release when a steady stream of water appear.

Electrical Connection

As wiring regulations differ from country to country, please refer to your LOCAL ELECTRICAL CODES for eld

wiring regulations and ensure that they are complied with. Besides, take note of the following general precaution:

1) Ensure that the rated voltage of the unit corresponds to the name plate before commencing wiring work.

2) Provide a power outlet to be used exclusively for each unit and a power supply disconnect and a circuitbreaker for over-current protection should be provided in the exclusive line.

3) The unit must be EARTH to prevent possible hazards due to insulation failure.

4) All wiring must be rmly connected.
