Sure-Aire™ Flow Monitoring System

User and Service Manual

2Sure-Aire™ Flow Monitoring System

Installation

1. Mount the controller in the vertical plane using four

#8-32 screws. Open the front cover by unscrewing

the two captive thumb screws to gain access to the

four mounting locations pictured at right.

Note: Mount the Sure-Aire controller within 75 feet

of the termination plate on the fan.

2. Use 1/4-inch nylon tubing to connect the

corresponding high and low, 1/4-inch quick connect,

pressure ports of the Sure-Aire controller to the high

and low pressure ports of the termination plate on

the fan.

3. Remove terminal block TB1 and perform wiring for

the pins listed below. For liquid tight applications,

use only 1/2-inch liquid tight conduit.

Terminal Block TB1: Input Power

Pin 1 = 24V, AC or DC (+ or -)

Pin 2 = 24V, AC or DC (+ or -)

Pin 3 = Earth Ground

4. Provide power to the controller to turn it on.

5. Select the desired Output Signal of the controller

for the Building Automation System. Use the touch

screen to select the 4-20 mA or 2-10 Vdc output

signal via the controller’s setup menu. (Refer to

Display Setting Options and Setup section, Output

Signal, pages 3 and 4).

6. Wire TB2 appropriately for the selected Output

Signal in Step 5.

Terminal Block TB2: Transmitter/Temperature

Sensor

Pin 1 = 4-20 mA or 2-10 Vdc (+) (output)

Note: 4 to 20 mA requires a load resistor

200-900 ohms

Pin 2 = 4-20 mA or 2-10 Vdc (-) (output)

Pin 3 = Shield

Pin 4 = Remote Temperature Sensor (input)

Pin 5 = Remote Temperature Sensor (input)

Note: Signal isolator may be required when two or

more output signals share a common connection at

the PLC/controller.

7. If temperature compensation is desired, mount the

provided temperature sensor in contact with the

airstream. Wire the temperature sensor into TB2

and change Temperature Comp to “Yes” via the

controller’s setup menu.

8. When the above steps are completed, make sure the

front cover is properly aligned to the housing and the

two captive thumb screws are securely tightened.

WARNING

Due to load resistance change from product to

product, it may be necessary to recalibrate the

4-20mA transmitter. See 4-20 mA calibration

procedure.

Sure-Aire™ Flow Monitoring System

NOTE

Apply a vacuum to the High Port and the 4-20 mA

transmitter will track the span of the pressure range.

i.e. The Sure-Aire controller with a pressure sensor

of 0 - 41.51 in. W.C. installed, 4.00 mA = 0 in. W.C.,

20.00 mA = 41.52 in. W.C.

WARNING

Due to load resistance change from product to

Temperature Sensor

Interconnect the remote temperature sensor by

connecting the temperature sensor to pins 4 and 5 of

TB2. The Remote Temperature Sensor will adjust the

air density value in the controller based on the sensor

measurement when Temperature Compensation is set

to ‘Yes’. This density compensation will affect the ﬂow

rate accordingly. If Temperature Compensation is set to

‘No’, the air density value will be a function of standard

air (70°F/21°C).
