ADJUSTMENTS
After installation, set the thermostat to the desired setpoint
and let the system operate long enough to stabilize. The
length of time required for stabilization depends on system
response time. This could be only a few minutes or as long
as several hours. Make certain that the system has
stabilized before checking calibration. If the temperature
stabilizes within one-half of the throttling range of the
setpoint, no calibration is required.
NOTE: All thermostats are accurately factory calibrated
and should require only a calibration (bleed-off)
check to ensure correct operation.
Throttling Range
Throttling ranges (TR) are factory set at 4F (2K) and
should not require any change under normal
operating conditions.
If a change in throttling range is necessary, reset the
throttling range to the values specified on the job drawings.
Use the following procedures:
1. Remove stat cover and install 0 to 30 psi
(0 to 207 kPa) gage in gage tap (Fig. 4)
2. Slide the TR indicator to the desired position on the
TR scale.
3. Mechanically check the TR by moving setpoint lever
to determine the difference in setpoint indication
when the branchline pressure reads 3 psi (21 kPa)
and 13 psi (91 kPa). (It may be necessary to turn the
calibration screw to adjust TR into the stat range.)
4. Reset TR to within ±2F (±1K) of required setting for
accurate control.
5. Follow RECALIBRATION procedures.
Calibration Check
To check calibration, the control space temperature must
be within the scale range of the thermostat.
On direct-acting bimetal elements:
1. Turn setpoint down five degrees below actual room
temperature and allow thermostat to build up
branchline pressure.
2. Turn setpoint indicator (Fig 4) up slowly.
3. If thermostat begins to bleed off between 1F (0.5C)
and 3F (1.5C) below room temperature, no further
calibration is necessary.
TP9600-TP9630 PNEUMATIC THERMOSTATS
On reverse-acting, bimetal elements:
1. Turn setpoint up five degrees above actual room
temperature as measured by a test
thermometer, and allow thermostat to build up
branchline pressure.
2. Turn down setpoint indicator (Fig. 4) slowly.
3. If thermostat begins to bleed off between 1F (0.5C)
and 3F (1.5C) above room temperature, no further
calibration is necessary.
