6. 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:
Fig. 6 Fig. 7
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.7).
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 controller also monitors pressure differential across the inlet and outlet of the
MagnaClean CMX
Nano filter via the integrated Grundfos DPS Sensor, providing warning alarms at two levels:
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) A full 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 can also be monitored by the DPS 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 9-10,
together with applicable warnings and alarms on page 11.
