Adjustments and Calibration
Thermal calibration is not required. Minimum and
maximum control points can be calibrated before or
after the thermostat has been installed.
1. Turn setscrews CW and remove cover.
2. Verify 16 VDC between the “+” and “–” terminals.
3. Remove setpoint slider stops (HFO-0027) if
necessary.
4. Measure “Tx” to “–” for output voltage. (See the
table on page 2 and the graphs on pages 3 and 4
to determine the correct T terminal.)
5. Maximum limits MUST be greater than
minimum limits. If in doubt, turn maximum limit
fully clockwise (increase) before proceeding.
NOTE: Dials rotate approximately 200° (8:00–4:00).
DO NOT force dial beyond stop.
6. Connect a voltmeter to the meter taps (using an
HSO-5001):
a. The two holes on the right are for the
minimum and maximum.
b. Measure actual flow in left holes. The
thermostat must be wired to a controller for
this option.
7. Always adjust the minimum first. Adjust setpoint
to request minimum flow using the minimum
dial:
• DA Cooling; Set point > Room Temp.
• RA heating; Set point < Room Temp.
NOTE : Limits may be set at the CSP series
controller or the thermostat. If setting min./
max. limits at the thermostat, the CSP’s
Min. dial must be turned fully CCW to “0”
AND the Max. dial must be turned fully
CW to “100.” This ensures that the CSP will
not affect the limits.
8. Adjust the setpoint to request maximum flow
using the Max. dial:
• RA Heating; Set point > Room Temp.
• DA Cooling; Set point < Room Temp.
9. Reinstall the cover and turn setscrews CCW until
the cover is secure.
