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.

Application Information

MFCU_(ii)

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.

Performance Data

The cooling and heating capacities of the fan coil units can be determined by the Cooling Capacity Perfor­mance Chart and Heating Capacity Performance Chart in the following pages based on nominal air flow at
standard water temperature. The total and sensible capacities must be adjusted as variables come in. A sample
of selection procedure is given as below:

Step 1

Determine type of fan coil units to be used, i.e. ceiling cassette (MCK-AW Series); ceiling exposed (MCM-DW
Series); etc.

Step 2

Select a tentative unit size based on cooling capacities at nominal air flow. Design entering air temperatures
and required water flows from cooling capacities chart

(Page 59 - 102) or the nominal capacities ratings (Page

45 - 55) from standard specification.

Step 3

Determine the nominal unit cooling capacities for the unit selected. If the cooling capacities chart must be used,
the following information must be known :-

a) Design water temperature rise
b) Design entering water temperature
c) Design entering air dry bulb temperature
d) Design entering air wet bulb temperature

Example of how to read the cooling performance chart.

Step 4

If air flow value is different from the nominal value(high speed), then refer to specification from Page 40 to 42
for the air flow required (medium or low speed). Determine the total and sensible correction factor from Air Flow
Capacity Correction Factor (Page 40 to 42)

Step 5

If the unit is to operate at an altitude above sea level, multiply the capacity correction factors by an Altitude
Correction Factors. Refer to Page 42.

Step 6

Calculate the actual cooling capacity by multiply the nominal capacity (from Step 3) with Air Flow Capacity
Correction Factor from Step 4 and the Altitude Correction Factor from Step 5.

Actual Capacity, W = Nominal capacity (Step 3) x Air Flow Capacity Correction Factor (Step 4)

x Altitude Correction Factor (Step 5)

Step 7

Water flow rate can be determined by:

Litres/Min =

Total Cooling Capacity, W

70 x Water Temperature Rise °C

USGPM =

Total Cooling Capacity, Btu/H

500 x Water Temperature Rise °F

Step 8

Heating Capacities at nominal air flow (Page 103 to 107

- Heating Performance Chart) are based on
standard condition of 60°C EWT and 21°C EAT. The actual heating capacity can be obtained by using the
Heating Capacity Correction Factor (Page 43 to 44) and Altitude Correction Factor as per Step 5.

Hence Actual Heating Capacity, W = Nominal Capacity (Page 137 to 141) x

Heating Capacity Correction Factor (Page 49) x
Air Flow Capacity Correction Factor (Step 4) x
Altitude Correction Factor (Step 5)

Step 9
Water Pressure Drop Tables are on Page 33 to 39.

EXAMPLE

Select a ceiling cassette type fan coil unit at the following design specification:

Room design condition : 27°C DB / 19°C WB
Room Cooling Load : 8 kW sensible capacity / 11 kW total capacity
Room Heating Load : 22 kW
Entering water temperature : 7°C cooling / 70°C heating
Water temperature rise : 5°C
Air Volume : 1000 CFM

m 006 :edutitlA

SOLUTION
Step 1

Based on the type of fan coil required and the design conditions, tentatively select MCK050AW. From the
cooling capacity performance chart (Page 80), at 26.7°C DB / 19°C WB air temperature, 7°C entering water
temperature and with 5°C water temperature rise, the cooling capacity for this unit is 11.7 kW total capacity
and 8.5 kW sensible capacity.

MFCU_(ii)

Performance Data

58

Step 2

Step 3

As the unit is operating at 600m above sea level, the Altitude correction factor is 0.98 total and 0.93 sensible.

Step 4

Multiply the cooling capacities obtained from step 1 (as per specification and design condition) by correction
factors from (2) and (3)

Actual total cooling capacity = 11.7 x 1.0 x 0.98 kW = 11.47 kW

Actual sensible cooling capacity = 8.5 x 1.0 x 0.93 kW = 7.91 kW

Step 5

Water flow rate = Litres/M =

11470 W

= 32.8

70 x 5

Step 6

From Heating Capacity Performance Chart

(Page 102), determine the heating capacity at the nominal air

volume by using the flow rate calculated in step 5. The heating capacity is at 20.6 kW.

Step 7

From Heating Capacity Correction Factor Tables at 70°C water entering temperature and 26.7°C entering air
temperature, the correction factor is 1.1261,

Actual Heating Capacity = 20.6 x 0.98 x 1.1261 = 22.7 kW

Step 8

Water Pressure Drop can be estimated from water Pressure Drop Table

(Page 33 to 39) using interpolate

method:

At flow rate of 32.8 Litres/Min, the nominal pressure drop is 39.14 kPa

Pressure drop correction factor = 1.2947 - 0.0021 x (EWT°C x 1.8 + 32) = 0.9629

Hence the actual pressure drop = nominal pressure drop x correction factor = 37.69 kPa.
