Adjustments and Calibration
Calibration
These thermostats are factory calibrated and normal-
ly do not require further calibration. If it is necessary
to change calibration:
1. Remove the cover and gauge-tap rubber caps.
2. Install a gauge on the gauge tap using 3/32" ID
tube.
3. Measure the ambient temperature with an
accurate thermometer.
4. Move the setpoint slider to the measured ambient
temperature.
5. Use a 1/16" hex wrench and turn the calibration
adjustment until the test gauge indicates the
desired pressure. (Clockwise rotation decreases
the output pressure.)
6. Replace the gauge tap rubber cap after
calibrating
.
7.
Place the setpoint slider to the desired
temperature and replace the cover.
Throttling Range
Throttling range is the temperature required to
change the thermostat output pressure from 3 to 15
psi. These thermostats are factory-set for a 3° F throt-
tling range. The approximate throttling range setting
is stamped on each lever in both °F and °C. If this
setting is changed, recheck calibration afterwards.
1. Remove the scale plate.
2. Slide the black “TR” adjuster to appropriate
value/ location.
NOTE:
The hole in the “TR” adjuster fits a 1/16"
hex wrench. Gently rotate the adjuster
back and forth while sliding.
Do not turn
excessively!
3. Rotate back to a “square” position after
adjustment.
4. Replace the scale plate (see the Mounting section).
