CTRL
The Safe-NET system is capable of controlling
temperature inside the refrigerated space of a refrigerated
merchandiser. The Safe-NET system can achieve this
control in the various ways discussed earlier.
This parameter selects the temperature input to use in
controlling the temperature of the refrigerated space.
Alarms and control set points are applied to this
temperature input source. Available sources are:
•
Product Simulator Average
•
Discharge Air Average
•
Return Air Average
•
Coil Temperature
Setting this parameter is done in the SETUP menu. After
navigating to the CTRL sub menu item, the display will
cycle between CTRL and the current setting. While the
setting is being displayed, press ENTER on the Hand-
Held device or press the SELECT button on the
Safe-NET display module to allow editing of the value.
When the Safe-NET display module begins flashing the
value, use the UP or DOWN arrow keys on the Hand-
Held device or the UP /DOWN buttons on the Safe-NET
display module to change the setting.
Once the desired setting is displayed, press the ENTER
key on the Hand-Held device or the SELECT button on
the Safe-NET display module to store the new value to
NV memory. The display will revert to cycling between
CTRL and the new value.
Note:
The Safe-NET system must be RESET for the new setting
to take effect.
One or more sensors of the type selected must be installed
Coil temperature always uses the coldest reading when more
than one coil sensor is installed. All other sensors are
averaged.
