Intellidyne IntelliCon-RU Operation Manual And Installation Instructions

OPERATION MANUAL and INSTALLATION INSTRUCTIONS for
IntelliCon ®
- RU
COMMERCIAL REFRIGERATION ENERGY ECONOMIZER
Description
®
The IntelliCon -RU is a patented microprocessor-based energy-
saving device for commercial refrigeration systems.
®
IntelliCon reduces electric consumption and lowers compressor
run-time by actively managing the compressor cycling pattern, in
conjunction with the existing compressor controls. Note that the
®
IntelliCon can not cause the compressor to run when the controls
are not calling for cooling.
compressor protection by eliminating compressor short-cycling.
This unit is compatible with Intellidyne's Remote Display Unit
(model RDU). In addition to Status, the RDU will also indicate total
compressor run-time and economizer time.

Operation
After installation, setting the slide switch on the top of the unit to
the 'ON' position activates the device. The lights on the front panel
indicate the state of operation of the device and will sequence as
the device goes through its operating cycle. Each light indicates
one of the possible modes of operation, which are:
STANDBY MODE:
shut off the compressor after cooling the space to the desired
temperature. The IntelliCon
compressor to start. This occurs for a period of time after the
compressor has shut down.
ECONOMIZING:
The refrigeration unit's compressor control has
requested the compressor to start but the IntelliCon
intervened to delay the start based on information it has gathered
from the previous run cycle.
COMPRESSOR ON:
ANTI-SHORT-CYCLE:
feature of the device, which ensures at least a thirty-second delay
between compressor starts. This light will illuminate whenever the
compressor has been turned off and will remain on for the thirty-
second protection period. The compressor can not be enabled
while this light is lit.
During normal operation, the top three lights will cycle from one
state to the next and the anti-short-cycle light will come on for
thirty-seconds after the compressor is stopped.
Installation
®
The IntelliCon -RU is electrically installed in series with the
refrigeration unit's compressor control as shown in the wiring
diagrams on the reverse side. Check and determine the voltages
of the compressor control circuit and power circuit prior to
installation. FOR SAFETY, POWER TO THE UNIT MUST BE
DISCONNECTED DURING INSTALLATION.
Positioning
The unit must be protected from the elements and may be
mounted on the equipment either vertically or horizontally. The unit
should be mounted directly on the existing electric enclosure via
the unit's standard ½" electrical fitting or within the enclosure using
an accessory mounting bracket. For mounting in the elements, a
rain-tight mounting enclosure is available.
Wiring
All wiring and connections must comply with Local and
National Electrical Codes. The unit should be wired as shown
in the wiring diagrams on the reverse side. It is important to
read all of the instructions carefully. Ensure that POWER TO

Checkout
Recheck wiring one last time. Set the IntelliCon
to 'Off/Bypass' and restore power to the compressor. Set the slide
switch to 'On'. First, as part of the system check, all four (4) lights
®
on the IntelliCon -RU will be briefly lit and then go out. Next,
either the 'STANDBY MODE', or the 'ECONOMIZING' light will
activate depending upon the operating state of the refrigeration
unit controls. The 'ANTI-SHORT-CYCLE' light will come on and
remain on for thirty-seconds.
After the thirty-second interval, the 'ANTI-SHORT-CYCLE' light will
go out. Next, if the 'ECONOMIZER' light is lit, after a short delay
the 'COMPRESSOR ON' light will light and the compressor should
start. If this happens, the installation is complete.
®
If the IntelliCon -RU remains in the 'STANDBY MODE' after the
'ANTI-SHORT-CYCLE' light goes out, it will be necessary to
simulate a cooling call to verify proper operation. Note the control
thermostat or pressuretrol setting and force a compressor call by
temporarily resetting the control. Verify that the IntelliCon
