7. Operation
Controller Overview: The unit controller is designed to be intuitive to use and allows functions and
alarms to be set by the installer/user. It also allows faults to be monitored and logged to enable easier
system fault diagnosis. The functions are set using the 4 buttons on the front of the controller, as per
below in Fig. 8:
Fig. 8 Fig. 9
The unit can be connected to a BMS system through RS485
- Modbus. The controller has been tested using ModScan
software. Connection is via RS485 protocol connecting the
positive data wire to MODBUS Terminal A and the negative
data wire to MODBUS Terminal B on the controller, (Fig.9).
The controller has three menu choices upon setup and during servicing which allow control over
access to important parameter settings for the product. The three menus are: Engineers Menu: 315;
Customer Data Menu: 815; Data Logging Menu: 111. Details about parameter access levels for each
menu type can be found from page 12 of this booklet.
The controller is fully programmable providing automatic on/off control, service interval alerts, unit and
pump failure alarms and system data logs covering servicing, operational hours & pump activity.
The integrated Grundfos 10-200L VFS Flow Sensor constantly monitors water flow through the
unit and system water temperature and the pressure differential across the inlet and outlet of the
MagnaClean CMX Midi filter via the integrated Grundfos DPS Sensor, providing warning alerts and
alarms at two levels:
Grundfos VFS Flow Sensor
a) A warning alarm, alerting the persons responsible for monitoring the heating or chilled system that l/
min flow through the unit has reached its warning level and that a service visit is advised;
b) An alarm, alerting the persons responsible for monitoring the heating or chilled system that
flow through the unit has reached its alarm level and that a service visit is required. The pump is
deactivated and the controller will not clear until a new service date is entered.
Grundfos DPS Pressure Differential Sensor
a) A warning alarm, alerting the persons responsible for monitoring the heating or chilled system that
the installed cartridge filter is beginning to block and that a service visit is advised;
b) An alarm, alerting the persons responsible for monitoring the heating or chilled system that the
installed cartridge filter is full and needs changing. The pump is deactivated and the controller will
not clear until a new service date is entered.
System temperature is also constantly monitored by the VFS Flow Sensor, providing warning alarms
should the water temperature fall below or above the programmable low/high temperature warning
parameters.
A full list of controller parameters and their factory default values can be found on pages 12-15,
together with applicable warnings and alarms on page 18.

*NOTE: When the “Magnet-Only Service Warning” alarm is activated, the alarm is a service reminder
only which can be reset by holding down the MUTE button for 5 seconds. When the alarm is reset
via the mute button, the alarm will reinstate the previous Parameter 2 & 3 values, e.g. if Parameter 2
is set to “Weekly” the controller will provide another warning alarm in 2 weeks until/unless default
parameters are manually updated/changed.

9. Filtration & Pressure Differential Monitoring
The integrated Grundfos Pressure Differential Sensor, (DPS) and DEK1002 controller
within these sidestream units monitor the pressure drop across the inlet and outlet of the
MagnaClean CMX Midi filter as the cartridge filters fill-up with captured system debris.
The controller has two preset warning and alarm settings based on debris collection rates within
the spun-bonded cartridge filters used with the CMX Midi filter. The first ‘warning’ setting sets off an
audible and visual alarm, warning that the installed cartridges are beginning to fill with debris and that
a service visit will be required soon. The second ‘alarm’ setting creates an audible and visual alarm,
warning that the installed cartridges are saturated with system debris, automatically switching off the
integrated pump. When this alarm function is activated, a service visit is required to clean the internal
magnet and replace the cartridge filters before the unit can be reset and put back into filtration mode.
For accurate pressure differential monitoring warnings and alarms, cartridge filters must be
installed in the filter housing; the DEK1002 controller does however feature programmable magnet-
only service warning alarms for when the sidestream skid unit filters are configured with magnets
only, with no cartridge filters installed. These magnet-only warnings are based on time elapsed rather
than differential pressure measurement across the filter, as there is no distinguishable pressure drop
across the filter without cartridges installed, even when they are full of captured magnetic debris.
These time-based alarms are important as ADEY always recommend that when a CMX
filter is installed onto an existing heating or chilled system, the filter should initially be
configured with magnets only. This is to ensure that cartridge filters aren’t needlessly wasted
& blocked with magnetic system debris. The programmable daily, weekly or monthly alarms
are intended as service reminders which can be easily reset within the controller menu.
After initial set up of the unit, we would recommend a service visit within 24-48 hours to check
magnetic debris capture levels and service as required. Subsequent service intervals will largely
depend on the amount of debris being captured. To ensure the unit is able to fully protect and filter the
system it is installed upon, regular servicing & maintenance of the CMX Midi filter is recommended.
Once magnetic capture rates begin to reduce, 5, 10, 20 or 50-micron cartridge filters should
then be installed to capture non-magnetic debris within the system whilst also assisting in the
capture of any remaining/reoccurring magnetic system debris in conjunction with the internal
magnet array and where required, the CMX Midi External Magnetic Jacket accessory.
However, there is no right or wrong way to configure the CMX Midi filter, which can be
configured with cartridge filters immediately if that is what you believe the system requires.
Please contact ADEY Customer Services on [phone] if you have any queries.

10. Flow & Temperature Measurement
The integrated Grundfos VFS Flow Sensor and DEK1002 controller within the MagnaClean
CMX Midi Pro Assist & Midi Pro units constantly monitor and log the temperature of the
system water and the amount of water that passes through them. BSRIA guidance states
that when using sidestream filtration, 100% of the system water volume should have passed
through the sidestream filter within a 24-hour period. The MagnaClean CMX Midi Pro Assist &
MagnaClean CMX Midi Pro units are designed for use on systems up to 93,000 litres in size.
The VFS flow sensor provides and logs real-time data around flow volume through the unit and filter:
a) Total water volume through the unit from the point of time the unit was last powered ON
b) Total water volume within the last 24 hours
c) Total water volume since the last Differential Pressure alarm activation
These facilities help meet the intent of BSRIA Guides BG 29/2021 Pre-Commission Cleaning of
Pipework Systems and BG 50/2021 Water Treatment for Closed Heating & Cooling Systems, for
products providing sidestream filtration and chemical dosing capabilities, as referenced in the
following sections of those guides and when installed in accordance with published guidelines:
- Sidestream filtration BG 29/2021; Section 2.3.8 and BG 50/2021; Section 3.4.2
- Chemical dosing facilities – BG29/2021; Section 2.3.8 and BG50/2021; Section 3.4.3
- Corrosion monitoring technology and services BG 29/2021; Section 2.3.8
The additional features of these products are also consistent with the descriptions in BG 50 including:
- Magnetic filtration BG 50/2021; Section 5.3.2
- Disposable media filters BG 50/2013; Section 5.3.3
- Passive deaeration BG 50/2013; Section 5.4.1
- Chemical water treatment BG 50/2021; Section 5.1
- Real-time monitoring of system parameters BG50/2021; Section 2.10
The VFS Sensor and DEK1002 controller also carefully monitor system water temperature
as it passes through the units. Low/high water temperature settings can be configured
as required, with automatic alarms when the configured low/high limits are reached. The
pump deactivates and the controller will not clear until a new service date is entered.
Both features help provide more pro-active maintenance, combining the security
of sensing technology with live data to warn you of critical system issues such as
pressure, temperature and flow and of course unit maintenance requirements,
ensuring the filter is always cleaning and protecting the system.
The ADEY MagnaClean Monitored Filtration™range actively monitors system flow, pressure
differential and system water temperature, offering configurable BMS alarm connectivity.
These solutions are designed to actively monitor the system water and the active filtration
of any heating or chilled system in a sidestream configuration for 24 hours a day.
