description
The MCCW module is able to control a water coil used for cooling. Together with the
EXact2 control system, the module is able to regulate the output from the water coil. If
necessary, a circulation pump can be started up.
NB The module is supplied as an MCOCW module.
It must be converted to an MCCW module by changing the following:
• Adding a jumper (supplied) to the module.
• Removing TE-RPT and TE-RPT-X sensors from the module.
See diagram in the section "Electrical installation" for further information.
The MCCW module can be used together with the following VEX/CX types:
• VEX100
• VEX200
• VEX320-370
• CX340-350
• VEX310T-VEX350T

Term Description input/output
TE-SUPPLY Measures air temperature after cooling coil. Temperature input
Capacity 0-10V Analogue outputs 0–10 V for setting of
0–100% cooling.
The MCCW module, via a temperature
regulator in EXact, sends an adjustable
0–10 V signal to the regulation valve (MVM).
Thus the setpoint for the supply air
temperature or room temperature is
maintained.

1 Fit the module using the screw holes in each corner of the module's
mounting box
2 Position the module in the vicinity of:
- regulation valve and pipes
3 Position the temperature sensor in the supply air duct as shown below
(Example from VEX200).

How to mount the temperature sensor correctly on the feed water pipe to the water coil:
2.3 Correct fitting of feed water temperature sensor
Step Action
1 Use heat paste to ensure good
contact between the pipe and the
sensor. Use strips to secure the
sensor in position.
2 Ensure there is sufficient
insulation around the sensor.

2.4.1 Connection of cooling coil
The dimensioning of valves, pipes, etc. and cooling coil connection must always be
carried out by authorised fitters in accordance with applicable regulations and
legislation.
Mixing loop See the simplified diagram.
Connecting an
insulated CCW
With an insulated CCW, the connection must be made with stopcocks and unions, in
order to allow easy release, extraction and cleaning of the coil.
NB
Do not connect the water coil like this!.
Connection without circulation pump risks frost damage!
Bleeding Following connection of water supply to the unit:
• Bleed the system thoroughly usin the upper bleed screw on the water coil.
Insufficient
bleeding Insufficient bleeding can result in still water forming in the system,
which may result in frost-induced leaks during the winter.
Fitting motor valve
The valve must not be fitted with the motor facing down.
Insulate supply
pipe and water coil The pipes and water coil must be insulated according to applicable
regulations.
Frost protection
The cooling coil can be protected against frost by mixing 25% ethylene
glycol. This provides frost protection down to -13°C.

2.4.2 MVM valve
Shielding Shield the valve motor from direct sunlight. Due to heat emission, the valve motor must
not be encapsulated (max. ambient temperature: 50°C).
Insulating the valveTo ensure normal operation at ambient temperatures below 0°C, it is very important that
the valve section is insulated according to current standards/procedures.
MVM-OD, valve for
outdoor fitting
IIf MVM-OD used, then shielding is part of the delivery - if the valve has a K vs value
below 6.3.
Regulating
properties
Optimal regulation is achieved when the differential pressure is between 5–20 kPa.
If the differential pressure is higher than 20 kPa, the installation of a pressure difference
regulator is recommended.
2.4.3 Cold water supply
The cold water supply must be constant.
2.4.4 Operation of circulating pump
The circulation pump is operated by the EXact control system, as described below:
1. When no cooling is required, the MVM valve operates at 0%.
2. The circulation pump runs for another 5 minutes and then stops.
3. EXact starts the 24-hour timer.
4. When the 24 hours have passed, the circulation pump runs for 5 minutes.
5. The exercise cycle is repeated once a day until a cooling requirement
occurs.

Funktions-
beskrivelse
MCCW-modulet kan styre en vandflade, som kan bruges til at køle. Sammen med
EXact2 styringen kan modulet regulere ydelsen på vandfladen. En cirkulationspumpe
kan startes ved behov.
Bemærk Modulet er leveret som MCOCW-modul. Det skal ombygges til et MCCW modul ved at
ændre følgende:
• Tilføje en lus (medleveret) i modulet.
• Fjerne TE-RPT og TE-RPT-X følere i modulet.
Se diagram i afsnittet “El-installation” for yderligere information.
MCCW-modulet kan benyttes sammen med følgende VEX/CX-typer:
• VEX100
• VEX200
• VEX320-370
• CX340-350
• VEX310T-VEX350T
Principskitse MCCW-modulet styrer en 3-vejs motorventil, som er tilsluttet en vandforsyning.
Vandforsyningen leverer koldt vand.

2.4.1 Tilslutning af køleflade
Dimensionering af ventiler og rør mv. samt tilslutning af fladen skal altid udføres af
autoriseret personale iht. gældende love og regler.
Blandesløjfe Her henvises til pricipskitse.
Tilslutning af
isoleret CCW
For isoleret CCW skal tilslutningen ske med stophaner og unioner, sådan at fladen let
kan løsnes, trækkes ud og rengøres.
Bemærk
Sådan må fladen ikke tilsluttes.
Tilslutning uden cirkulationspumpe medfører risiko for frostsprængning.
Udluftning Efter tilslutning af vand på aggregatet:
• Udluft systemet grundigt via den øverste udluftningsskrue på vandfladen.
Manglende
udluftning Ved manglende udluftning er der risiko for stillestående vand i systemet,
hvilket kan medføre frostsprængninger i kolde perioder.
Montage af
motorventil Ventilen må ikke monteres med motoren nedad.
Isoler fremløbsrør
og vandflade Rør og vandflade skal isoleres i henhold til gældende krav.
Frostsikring
Kølefladen kan frostsikres ved at iblande kølevandet 25% ethylen-glycol.
Herved opnås frostsikring ned til -13°C.
2.4 Køleflade
