Fan Static Reset Kit
The Fan Static Reset Kit accurately measures the static pressure drop
across a clean air valve and provides feedback to the Building
Management System (BMS) to optimize fan control. The sensor is
housed in a rugged polycarbonate enclosure, which mounts directly to
the valve base channel and has a 3-wire connection to the valve
mounted controller for power and signal. Two pressure pickups, two
pressure dampers and two, six foot lengths of silicon tubing are
included for mounting upstream and downstream of the valve to
obtain optimized pressure readings. One device with a range of 0.0 to
5.0" W.C. covers both medium and low pressure valves and allows for
dynamic fan control to reduce energy consumption under varying
flow conditions.
FEATURES
• Precision sensor provides accurate control feedback value
• Sensor mounts directly on valve base channel
• Pressure value is available network wide
• BMS can dynamically monitor and control fan static
• Maximize energy savings by running fans at lowest possible static

ORDERING GUIDE
APPLICATIONS
The Fan Static Reset (FSR) kit measures the pressure drop across select Accel II valves and passes this value across the network to
allow the BMS to potentially save energy by optimizing fan speed control. By continuously monitoring the static pressure at the
lowest point in the system, the BMS can trim fan speed as flow conditions and static pressure in the system changes. The intent is
to control the fans at the lowest practical speed to gain whatever energy savings is possible while ensuring there is sufficient static
pressure for the pressure independent cone assembly to maintain the desired flow.
The FSR is intended to be installed across the valves in the duct runs believed to be the "worst case" in terms of pressure loss. These
are typically the furthest from the fans or with the greatest number transitions, turns, or obstructions such as filter coils or dampers.
A review of the duct layout drawings can provide clues to the location of the valve that will see the lowest system pressure, however,
the lowest point may change based on different operational conditions. Spot checking may be the best way to determine the low
point or it may be prudent to select a number of locations to install FSRs and perform a low-select as system conditions vary.
The FSR100 is intended for installation on "Clean air" (Supply or General Exhaust) valves. The materials of construction of the
pressure pickup, tubing and the pressure sensor itself are not suitable for applications with corrosive or condensing vapors.
Additionally, the fume hood valve controller does not have inputs available for connecting the pressure sensor or network variables
for passing the value across the network. Therefore it should not be used on fume hood applications.
The FSR mounts on the valve base channel. The pressure pickups are installed in the duct work upstream and downstream of the
valve and the pressure sensor is connected to the power source and available universal input of the valve controller. Then the
Universal Input (UI) signal is scaled in the Configuration Plug-in program according to actual field measurements of pressure from
the sensor.
It is important to recognize accuracies, errors and tolerances, as well as response times throughout the entire sensing and control
system when choosing a static pressure control setpoint. If the total potential error (transmitter accuracy and temperature error) is
±0.1 inch W.C. and the valves have a 1 second speed of response while the fan speed controller may require 20 to 30 seconds to
respond to a change in setpoint, there must be sufficient safety margin in the setpoint to ensure the static pressure at the valve is
never compromised.

INSTALLATION
The Fan Static Reset kit comes complete with all the components and mounting hardware necessary for installation. The pressure
sensor mounts to the valve base channel and gets its power from the valve controller and connects to any available UI on the valve
controller. The pressure pickups are mounted upstream and downstream of the valve and connected using the two supplied sets of
silicon tubing and pressure dampers. Nylon wire ties and self-adhesive mounts may be used to secure the silicon tubing to the duct.
Mounting the sensor
The sensor is attached to a mounting bracket that can be mounted in several locations on the base channel depending on the size of
the valve, its actuator type and what options are installed. Two locations, opposite the electronics enclosure have existing holes and
are preferred for mounting the sensor (see 1 and 2 below). Two alternate locations, on opposite corners of the base channel (3 and 4
below) require the use of self-drilling, "Zip" screws. Use care when using the "Zip" screws so they do not pierce the valve body.
1May be used if the preferred locations are obstructed by other components on the base channel
NOTE: Mount the sensor bracket using two screws in an orientation that allows access to the electrical connection port and
permits the enclosure door to open allowing access to the internal wire connections.
Guidelines for locating the pressure pickups
For stable and accurate readings the duct runs immediately upstream and downstream must be straight and free of any obstructions
such as bends, transitions, filters, dampers and coils. Per ANSI/ASHRAE 130-2008 Methods of Testing Air Terminal Units, the duct
immediately upstream and downstream of the valve must be uniform in shape with no obstructions for a minimum of 3.0
equivalent duct diameters upstream, and 3.5 equivalent duct diameters downstream of the valve. Anything less than the 3
uninterrupted duct diameters upstream and 3.5 diameters downstream is highly suspect and should not be used. The longer the
straight uninterrupted duct runs upstream and downstream of the valve, the better the flow profile and the more stable and accurate
the readings you will achieve.
Additionally, the pressure pickups must be a minimum of 1.5 equivalent duct diameters upstream and 2.5 equivalent duct
diameters downstream away from the valve. Any closer to the valve and turbulence from the valve components in the flow stream
will likely compromise the stability and accuracy of any readings. As a general rule, the area within a minimum of 1.5 equivalent
duct diameters downstream or upstream of any obstruction would be a poor location for the pressure pickup. The further away the
pressure pickups are located from the valve and any other obstruction, the more stable and accurate the readings will be.

NOTE: These guidelines should provide adequate readings. However, the only way to confirm the suitability of the pressure
pickup location is to perform a full duct traverse following the procedures outlined in the ANSI/ASHRAE 111-2008
Measurement, Testing, Adjusting, and Balancing of Building HVAC Systems. If the pressure reading at the pressure
pickup is within 5% of the values measured when the duct was traversed, this is the optimum location.
The pressure pickups must be located in a position on the duct that will not be susceptible to becoming clogged or allow
condensation to enter the sensing tubes. On round or oval duct, it is recommended the pressure pickups be placed in the upper
portion of the circumference of the duct between 8 and 4 o'clock. On rectangular duct, the preferred placement of pressure pickups
is on top of the duct, well away from the corners. Other acceptable locations are at least 2-3" (51-76 mm) up the side wall of the
duct and not near any corner of the duct. Mounting the pressure pickups on the bottom of the duct is not permitted.
Mounting the pressure pickups
The pressure pickups are mounted directly to the duct using 2 self-drilling "Zip" screws (included). A closed cell foam gasket seals
the pressure pickup to the duct.
Once you have determined the proper location of the pressure pickup, you will need an area free of any insulation. The pressure
pickups must be mounted directly on the duct surface. The pressure pickups may not be used on double-walled or lined duct. If the
duct is double-walled, contact your Phoenix Controls Representative for recommendations.
1. Orient the pressure pickup so that the arrow etched on the mount plate indicates the airflow direction.
NOTE: It is important that the top and bottom mounting screws are oriented perpendicular to the direction of airflow so as
not to cause obstructions near the pickup.

2. Using 4 of the Zip screws (included) attach first one, then the other pressure pickup to the duct compressing the gasket evenly
top and bottom.
NOTE: Be careful not to over-tighten the screws and deform the plate or strip the mounting holes.
We recommend tightening to no more then 12 in.-lb. (1.35 Newton-meters).
3. Next, using the pressure pickup barb as a guide, drill a hole between 5/64" (.078"/1.98 mm) and 7/64" (.109"/2.77 mm) in
the duct wall.
WARNING: Use care so as not to damage the barb with the drill bit.
4. Attach the short length of silicon tube containing the pressure damper, to the pressure pickup barb.
NOTE: Make certain that the pressure damper is oriented in the proper direction (arrow pointing AWAY from the pickup) as
it is not bi-directional.
5. Connect one end of the longer piece of silicon tubing to the pressure damper.

6. Cut it to length and connect it to the appropriate port on the sensor.
• Upstream or "fan side" of the valve connects to the "H" (high) port on the sensor.
• Downstream or "room side" of the valve connects to the "L" (low) port on the sensor.
NOTE: Make certain the tubing is not kinked and not in a position where moving parts on the valve could pinch or cut it.
7. Secure the tubing to the duct using the enclosed tie wraps and adhesive backed holders, or duct tape so that it cannot become
tangled with any moving equipment in the area.
WARNING: Phoenix Controls recommends a "drip loop" somewhere along the tubing run to prevent moisture or
condensation from reaching the ports on the pressure sensor. Moisture will damage the sensor beyond repair.

WIRING THE PRESSURE SENSOR
The pressure sensor is a 3-wire device; power, signal and circuit common. Three white crimp-on connectors are provided with the
kit and are used to connect the wires coming off of the sensor printed circuit board (PCB) with a 3-conductor cable (provided by
others) that terminates in the valve mounted controller enclosure. This cable leaves the sensor housing via the pre-drilled conduit
port opposite the pressure ports so no enclosure modifications are required in the field.
A 3-conductor cable must be run between the pressure sensor enclosure and the valve mounted controller enclosure. Wiring details
follow.
NOTE: Lead wire lengths will impact signal output/accuracy. Cable length should be limited to 5 to 10 feet (1.5 to 3 meters).
At the Sensor
• Red wire is for power
• White wire is for signal "+"
• Black wire is for circuit common
At the Celeris High-Speed Electric Controller
• FSR power wire terminates on TB4, Terminal 1 (L1)

PHOENIX CONTROLS WIRING RECOMMENDATIONS
• All circuits must conform to the requirements of an NEC Class 2 (dry) circuit
• Use multiple transformers instead of larger transformers when more than 100 VA is required
• Each pressurization zone should have either a dedicated single-phase primary circuit, or a secondary circuit disconnect
• Use cable sizes recommended by Phoenix Controls (see Table 2)
• Use stranded wire for ease of installation
• Follow good wiring practices:
• Locate cables away from sources of electrical interference (EMI/RFI)
• Do not run signal or communication cable in the same conduit or wire way as power cables
• If signal cable must cross power cables place these at a 90-degree angle
• Shield or drain wires, if required, should be wrapped with insulating tape to prevent contact with exposed conductors or
contacts
• Maintain a consistent color code or polarity all the way through the wiring system
• Power supply and signal isolation on I/O devices vary from manufacturer to manufacturer. Verify the wiring device manufac-
turer's recommendations for isolating power and signal common connections and maintain polarity
• Local and national electrical codes take precedence
• Strip 0.25" (6.4 mm) of insulation from each conductor, twist the strands, insert the conductor fully into the terminal block,
and tighten the terminal
• Test the wire connection by pulling on each conductor
• See “Phoenix Recommended Cables” on page 11, for approved cable manufacturers and wire types
MAINTENANCE
There are no user serviceable components in the Fan Static Reset Kit. If you suspect the pressure sensor is not sending out a signal,
first check the power wiring to ensure the sensor has power.

TROUBLESHOOTING
There is no signal input • Check for power between the red and black wires
• Power should be between 7 to 40 Vdc or 7 to 32 Vac
• If no voltage is present check power source at the controller and interconnecting
cable
• If voltage is present, disconnect all other devices from the controller to see if the
signal returns
• Disconnect the white signal wire going to the controller and using a volt meter,
check for a signal voltage
If the device has a proper power source and there is no output signal with all other
devices disconnected, it must be returned to the factory for replacement.
The output signal appears to be
incorrect
• With no differential pressure across the sensor, the output signal should be 0.25
Vdc ±0.06 Vdc
• Disconnect the tubing and connect a short piece of tubing across both the high
and low pressure ports to shunt the high and low to the same value. The voltage
output should be 0.25 Vdc
- If the signal is 0.25 Vdc but the pressure variable does not read 0, make
sure the scaling in the Configuration Plug-in indicates 0.25 Vdc = 0" W.C.
- If the zero output has shifted, there are no user adjustments on the sensor
itself so the Configuration Plug-in must be used to rescale the input voltage
(ex. 0.45 Vdc = 0" W.C.)
• With differential pressure across the sensor if you suspect the signal is reading
incorrectly
• There is no span adjustment on the pressure sensor. If a duct traverse indicates
there is an error, the only option is to use the Configuration Plug-in to adjust the
scaling of the input voltage range. For example, if 0" W.C. is at 0.45 Vdc and 5"
W.C. is at 4.75 Vdc, the Configuration Plug-in scaling needs to indicate 0.45
Vdc = 0" W.C. and 4.75 Vdc = 5" W.C.
