Controller Calibration
Minimum and Maximum Flow Limits
Minimum and maximum flow limits are often set at
the thermostat. ( For instructions on setting the flow
limits at the thermostat and other information, see
the
CSP-5001/5002 Application Guide
or
CTE-5202
Applications Guide .)
If desired, the minimum and maximum limits can
be defined by adjusting the appropriate setpoints
within the CSP-500x controller (see below) instead,
but
do not try to set the limits at BOTH the con-
troller and the thermostat (or else the limits will
not reflect either the controller’s or the thermo-
stat’s limits) .
To set the velocity limits at the CSP-500x:
1. Remove the access door by pulling back on the
door’s tab and lifting upward.
2. Connect a voltmeter to the meter taps (using
HSO-5001 test leads).
3. Move the jumper from the NOR (normal) position
(two left-most pins) to the MIN position (two
right-most pins).
4. Adjust the MIN potentiometer for the desired
minimum voltage.
NOTE: MIN must be adjusted first.
5. Move the jumper to the MAX position (two center
pins).
6. Adjust the MAX potentiometer to the desired
maximum voltage.
7. Return the jumper to the NOR position.
VNOM (CFM) Range Setting
NOTE: In the controller, VNOM stands for
“NOMinal Volumetric flow rate.”
The CSP-500x range is factory-calibrated with the
VNOM potentiometer centered. Using any SSS-1000
series velocity pickup, tubing, and reducers, the CSP-
500x will have a range of 0–3,300 fpm with a 0–10
VDC reset control signal from the thermostat.
Leaving the VNOM at the factory setting is recom-
mended! Changing the VNOM potentiometer from
the factory setting will alter the calibration between
the “IN” and “OUT” voltages. However, the VNOM
can be adjusted to match 0–10 volts to a specific
velocity range if desired.
To set the VNOM range:
1. Remove the access door by pulling back on the
door’s tab and lifting upward.
2. Supply the desired velocity to the “H” and “L”
ports.
3. Connect a voltmeter between the “OUT” and “–”
terminals and adjust the VNOM potentiometer
until the voltage equals 10 VDC.
