Installation Guide
Air Flow Sensor Connection
The CSP-500x is factory calibrated to function with
an SSS-1000 series differential pressure flow sensor.
Using 24" of 1/4" OD x 0.040" wall “FR” instrument
and control tubing, a 3/8" to 1/4" barb union adapter,
and 1" of 3/8" OD x 0.062 “FR” tubing for both con-
nections:
1. Connect the “H” port to the (high side) “H” of the
sensor.
2. Connect the “L” port to the (low side) “L” of the
sensor.
NOTE: To maintain a close correlation with the
factory calibration (for 0 to 3300 fpm), the
3/8" OD tubing between the sensor and the
adapter should be as short as possible, and
the 1/4" OD tubing from the adapter to the
controller should be exactly 24" long (on
both the High and the Low sides) without
other restrictions such as fittings or kinks.
NOTE: The SSS-1000 series differential pressure
flow sensor must be mounted with the
arrow pointing in the direction of the air
flow.
Wiring
1. Remove the CSP-500x's wiring access door by
pulling back on the door’s tab and lifting upward.
2. Access for wire or cable is via two 5/8 in. (16 mm)
diameter snap-in shutter bushings located on the
bottom of the cover.
3. Remove the snap-in shutter bushing and replace
with one the following connectors as needed
(connectors are not supplied—order separately):
A. HMO-4518 for 1/2 in. flexible conduit.
B. HMO-4520 compression connector for plenum
rated cable.
C. HMO-4526 female connector 1/2 in. conduit.
4. Connect the CSP-500x to a CTE-5100 series or a
CTE-5202 thermostat:
A. Terminal “16 VDC” to thermostat terminal “+”
(CTE-5100 series) or “~” (CTE-5202).
B. Terminal “IN” to thermostat terminal “T1/AO1”
for cooling (“T2/AO2” for heating) air flow.
NOTE: If minimum and maximum velocity limits
will be set at the CSP-500x (see
and Maximum Flow Limits on page 4
),
then use “T3” for cooling and “T4” for
heating on a CTE-5100 series thermostat.
C. Terminal “OUT” to thermostat terminal “V1”
for velocity readout at the thermostat.
D. Terminal “–” to thermostat terminal “–/
T
”
(Common).
5. Connect the CSP-500x to a 24 VAC, –15/+20%,
50/60 Hz, 4 VA, Class 2 only power source:
A. Terminal “~” to the phase side of the
transformer.
B. Terminal “–” to the neutral or ground side of
the transformer.
6. Reinsert the wiring access door.

Maintenance
No routine maintenance is required. Each compo-
nent is designed for dependable, long-term reliabil-
ity, and performance. Careful installation will also
ensure long-term reliability and performance.
