Sporlan Secondary Fluid Control Quick Reference Manual

Secondary Fluid Control with Remote Display
Quick Reference Guide
SD-377rd
The Sporlan Secondary Fluid Control should be installed only by a qualified professional. All other system components (valves and
sensors) should be supplied by Sporlan to ensure compatibility and proper operation. There are no user-serviceable components inside
the controller. Opening the case will void the warranty.
Use caution when working around high voltage components.
Safety covers should be used for personal safety on high voltage panels.
Tools required:
• Small flat screwdriver for terminal
connections
• Cordless screwdriver
• Phillips and flat screwdrivers
• Needle-nose pliers
• Wire cutters
• Scotch-Brite pad
• Two #8 X ½" self-tapping screws to
mount DIN rail
• Six cable ties
• CAT5 Ethernet cable
• Remote display communication cable
1. INSTALLATION
Refer to diagram on back of this guide.
1. Mount the controller in a rain-tight,
protected location using the supplied
DIN rail. To leave enough working
space, the suggested mounting area
is 10" high, 5" wide and minimum
depth of 3" .
2. Mount the remote display through
a panel cutout using the provided
plastic retainer. Rough opening
dimensions required are 2.50" x
1.14" with a bulkhead thickness of
3/16" maximum.
3. Mount the coil inlet, coil outlet, dis-
charge air and defrost termination
(optional) temperature sensors. For
further details on sensor installation,
reference Installation and Operation
Bulletin 100-50-5.4rd.
NOTE: Sensors are color coded for ease
of installation.
Coil Inlet (supply) = Blue
Coil Outlet (return) = Black
Discharge Air = Green
Defrost Termination = Yellow
4. Connect the Inlet liquid temperature
sensor wires to terminals 29 and 30
(blue jacket). The sensor is not polar-
ized. Maximum torque on screw
terminals is 3.5 in-lbs.
5. Connect the Outlet liquid temperature
Controller v. A
sensor wires to terminals 27 and
28 (black jacket). The sensor is not
polarized.
6. Connect the Discharge air tempera-
ture sensor wires to terminals 31 and
32 (green jacket). The sensor is not
polarized.
7. Connect the Defrost Termination
temperature sensor (optional) to ter-
minals 25 and 26 (yellow jacket). The
sensor is not polarized.
8. Connect the Sporlan SFV wires to
terminals 5, 6, 7, and 8. Valve wires
are color coded.
9. Connect externally controlled load
(e.g. lights) to the internal relay on
terminals 19 and 20 (120-240 VAC,
3A max).
10. Connect external load control relay
to the digital output (24 VDC pilot)
on terminals 11 and 12.
11. Connect the controller to the remote
display.
12. Connect power to terminals 1 and
2. Transformer requirements are 24
volts AC at 40 VA, Class II.
WARNING: Use caution when
working around high voltage com-
ponents. Safety covers should be
used for personal safety on high
voltage panels.
NOTE: The Sporlan SFV Control should
be installed only by a qualified
professional. All other system
components (valves and sensors)
should be supplied by Sporlan to
ensure compatibility and proper
operation. There are no user-
serviceable components inside
controller. Opening the case will
void the warranty.
2. SETUP
Ensure all connections have been made
before applying power. The SFV is
initialized upon start up, and the system
will not operate until completing setup.
Once powered up, the controller will
display the firmware versions and then
the first variable to set. To change setup
parameters, use the arrows to set the
desired value, and then press the SET
button.
1. Set dAS, Discharge Air Setpoint.
Default is 28°F.
2. Set dtY, Defrost Type. Default is oFF
for off time defrost. If warm fluid
defrost is required, select FLU. If
Electric defrost, select ELE.
3. Set Add, network address, between 1
and 247.
4. O nce setup is complete, the control-
ler will display dAt, Discharge Air
temperature. After the system is in
operation, verify that the Discharge
Air Setpoint, dAS, is met.
3. SETPOINT MENU OPERATION
For further system tuning, adjust param-
eter setpoints as described below and in
Bulletin 100-50-5.4rd.
NOTE: The Parameter Menu times out
after 60 seconds of inactivity and
all changes will be lost.
1. E nter the Parameter Menu: Press and
hold the SET button for 5 seconds.
Use the arrows to enter the pass-
word "111" and press the SET button
again.
2. T o change a parameter, select the
desired parameter using the arrows
and press the SET button. The
default value will display.
3. U se the arrows to change the value
and then press the SET button to
enter the value and return to the
Parameter Menu.
4. A fter all parameters are set, use the
arrows to select " ESC " and press
the SET button to save all changes.
