Control
Note: The ON differential in both “General” and “Child” units
must always be >0, otherwise the unit will never be
activated.
CALIBRATION
In the “Calibration” section, which is password protected to Level
2, the user can adjust the readings of the sensors connected to
the units to match the readings on a measurement standard.
Additionally, it is possible to set the logical operation of the digital
inputs; these can be “Regularly Open” (NO) or “Regularly Closed”
(NC).
It is also possible to calibrate the minimum flow rate allowed to
start the system, the Water Chiller Unit system needs 2.4 gallons/
min per Ton.
If you have a 10 Ton Water Chiller Unit you will need 24 gallons/min.
If the hydraulic installation cannot provide this flow, it is possible to
operate the equipment at 80% of the required flow to avoid flow
alarms, be cautious if you decrease to less than 80% as this can
cause serious problems in your system such as inefficiency and
lack of rated capacity.
For water heat pumps you will see the condenser sensor, do
not change the maximum and minimum values, these must be
configured in the installation.
This type of sensor cannot measure more than 39.6 gal/min, in
case you get a value higher than this, the display will show 295.6
approx. Check your hydraulic system to regulate the flow.
The value considered acceptable will be the same for the
evaporator sensor.
EXPORT OF RECORDS
Also in the “Son” section it is possible to configure the switching on
and off of the same, this configuration is a prevention to avoid the
freezing or cold water alarm in the “Tandem” mode, this function is
the same as in “General” and respective to the set point.
The user can export to a USB Flash Drive all the information stored
in the unit by means of a comma separated file (CSV). The user
can export 3 different files with different information:
• The Alarm Log
• The injection temperature of the “Mother” unit and if available,
the temperatures of the Mother unit.
• The injection temperature of the “Child” units (if any are present
in the system).
