Functional
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

diagram
The MCCW module controls a 3-way motor valve connected to a water supply.
The water supply provides cold water.
.
Mixing loop Constant flow in the primary circuit (Supply) and in secondary circuit (Coil Cold Water)

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.
Analogue output

MVM 3-way motor valve

TE-SPT Temperature sensor measures the feed
temperature to the cooling coil.

Fitting the MCCW
module
The temperature

positioned here
2.1 Positioning and fitting of the MCCW module
Step Action
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.
