OVERVIEW
Models GF-A2100 and GF-A2200 are high quality economi-
cal programmable dual-output airflow/temperature meas-
urement and control instruments with options for analog air
flow, temperature, alarm, and corresponding PID control out-
puts for control of airflow set points. They are designed for
installation in specified critical applications that require pre-
cise measurement of air flow (down to zero flow) and temper-
ature, with available PID control for air flow set point. The
instrument includes factory calibrated probes (one with GF-
A2100, two with GF-A2200) and an advanced microproces-
sor controlled transmitter/controller with typical sensor accu-
racy of 3% of reading (4% maximum)* from 0 - 2,000 FPM.
Figure 1. GF-A2100/GF-A2200
Airflow Measurement Station
* Sensor accuracy is the calibrated accuracy of the individual sensor. The installed accuracy of the overall airflow station is application-dependent on the resulting sen-
sor density; typically better than 15% of reading.
Each sensor probe is equipped with a high reliability bead-in-glass heated thermistor element, factory calibrated to NIST
traceable standards from zero flow to 2,000 FPM. The transmitter is fully independent of the probe and does not require
field matching to the probe. An advanced microprocessor processes the raw probe signals and provides versatile pro-
grammable airflow measurement and alarm options with direct LED drive or N.O./N.C. relay dry contacts, and selectable
analog output signal options. A powerful variable input signal integration option can be engaged to reduce the effects
of transient input signal variations, and an innovative Field Calibration Wizard allows for simple, automated field adjust-
ment of the instrument if required. A 16 character LCD display indicates airflow, temperature, system status and is also
used for configuration and diagnostics. Field configuration is accomplished using a simple four-button user interface.
Individual airflow and temperature measurements can be displayed for use in HVAC system diagnostics.
An input signal filter with variable buffer integration can be engaged for transient flows, and a process low limit can be
set to force the output to zero when the airflow rate falls below a low limit. Both features are beneficial on outside air
intakes affected by transient wind gusts at low airflow rates. A simple to use Field Calibration Wizard permits one or two
point field adjustment to factory calibration for installations that require field calibration or adjustment. The transmitter
provides two independent programmable analog outputs with full scale ranges of 0-10VDC, 0-5VDC or 2-10VDC.

FEATURES
INSTALLATION
Installation consists first of installing the sensor probe(s), then installing the transmitter, and last, installing the power
and analog signal wiring to the airflow station. The following paragraphs detail the individual procedures and steps
required for installation of the single probe GF-A2100 and dual probe GF-A2200. Convenient check boxes are included
at each step.
Preparation for Installation
1. Determine the GreenTrol factory specified location for the GF-A2100/GF-A2200 airflow measuring station trans-
mitter and probe as indicated on the engineer's plans. Ensure that the cable supplied with the probe is of sufficient
length to reach the planned transmitter installation site. It is recommended that the probe be installed first to
ensure that the included cable will reach the transmitter after allowance for routing and securing the cable.
2. Carefully unpack the GF-A2100/GF-A2200 and inspect the transmitter and probe(s) for damage. If damage is
noted, immediately file a claim with carrier. Proceed to install the GF-A2100/GF-A2200 sensor probe(s) as outlined
in the appropriate procedures that follow for Universal Mounting Brackets or for Insertion Mounting Brackets.

Universal Mounting Bracket Probe Installation
The installation objective is to install probes so that the probe sensor center line is located at the exact position in
the duct/plenum as shown in Figure 4.
1. Sensor probes must be installed at the factory-specified location using the integral universal bracket attached as
shown in Figure 3. The universal bracket consists of a rubber probe clamp that is attached to the bracket using the
included hardware. Probes can be rotated within the clamp, and the clamp can be rotated and mounted at any point
along the 4-inch slot on the mounting bracket, thus providing complete mounting flexibility and adjustment.
Assemble probe to the clamp and bracket so that when mounted, air flow is through the probe sensor opening, and
in the same direction printed on the probe label.
2. Using the engineer’s plans, mark the two mounting holes for each probe bracket at the GreenTrol factory-speci-
fied location where the probe(s) will be installed.
3. Drill holes suitable for the hardware that will be used to secure the bracket at two locations.
4. Carefully align the bracket mounting holes with the holes prepared in the previous step.
5. Secure each probe bracket and probe in two places through each bracket using suitable hardware. Adjust each
bracket mount and/or probe clamp so that the airflow arrow printed on the probe is oriented in the direction of actu-
al airflow.
6. Route each sensor probe cable to the planned transmitter site and install transmitter as outlined in the TRANS-
MITTER INSTALLATION procedure that follows.

Insertion Mounting Bracket Probe Installation
The installation objective is to install probes so that the probe sensor center location is at the exact position in the
duct/plenum as shown in Figure 6 (for single probe model GF-A2100) or Figure 7 (for two-probe model GF-A2200).
1. For the duct/plenum probe insertion point mark, measure and record the duct/plenum height at the side where
the probe is to be installed as shown in Figures 5 through 7. At 1/2 of the measured duct/plenum height, mark the
probe insertion point on the duct/plenum to ensure that when the probe is inserted, its sensor center location will
be at the exact position in the duct/plenum as shown in Figure 6 (for GF-A2100) or Figure 7 (for GF-A2200)
2. 
For single probe model GF-A2100:
For the probe insertion depth mark, refer to Figures 5 and 6. Calculate and record the sum of (1
1/2
of dimension ‘D’
+ 3 inches {76.2 mm} + insertion wall insulation thickness). Measure from the non-cabled end of the probe and
mark the probe across the factory score line at this point. This will serve as the probe insertion mark.
OR

For two probe model GF-A2200:
For the probe insertion depth mark, refer to Figures 5 and 7. Calculate and record the sum of (1
1/4
of dimension ‘D’
+ 3 inches {76.2 mm} + insertion wall insulation thickness). Measure from the non-cabled end of each probe and
mark each probe across the factory score line at this point. This will serve as the probe insertion mark.
3. Prepare the probe insertion hole(s) (one for the GF-A2100, two holes for the GF-A2200) at the location(s) marked
in step 1 using a 0.875 inches (22.2 mm) hole saw.
4. Temporarily slide the probe and bracket through the hole prepared in step 3 so that the airflow label on the brack-
et is parallel to and in the same direction of duct/plenum airflow. Mark the four mounting bracket hole locations for
each probe.
5. Remove probe from duct/plenum and then prepare suitable mounting holes for the field supplied hardware that
will be used to secure the mounting bracket.
6. Slide the gasket seal down the probe body to the bracket. Carefully position the probe in the insertion hole pre-
pared in step 3 so that the airflow label on the bracket is aligned with the actual airflow in the duct/plenum. Insert
the probe so that the probe insertion depth mark (step 2) is just visible at the insertion mark target on the nylon
bracket block. Secure the probe at this location using the setscrew on the mounting bracket nylon block. (Refer to
Figures 5 and 7 for detail).
7. Ensure that the edge of the probe mounting bracket is parallel to the edge of the duct, and that the airflow arrow
printed on it is oriented in the same direction as duct/plenum airflow. Secure the probe mounting bracket at the four
holes prepared in step 5 using suitable hardware.
8. For two probe model GF-A2200, repeat steps 4 through 7 for the remaining probe supplied.
9. Route the sensor probe cable(s) to the transmitter location.
10. Install transmitter as outlined in the TRANSMITTER INSTALLATION section of this document.
