Changeover Point Adjustment
Limit Stop Adjustment
The changeover point is factory set to occur between 19
and 22 psi (131 and 152 kPa). The changeover point can
be field adjustable to occur between 14 and 22 psi (96 and
152 kPa).
Thermostat limit stops define the minimum and maximum
thermostat set points. The limit stops engage in the set
point cam gear teeth and cause interference between the
set point cam gear and the adjustment knob gear.
To change the limit stop settings, use a needle nose pliers
to pull the limit stop (Figure 3) between the set point cam
gear teeth. Do not pull limit stop any more than necessary
to clear the gear teeth. Rotate the limit stop to its new
position. Changing the limit stop position one gear tooth
changes the limit stop setting by 1-1/3F (0.7C).
1. Connect a pressure gauge or a manometer to measure
the supply pressure to the thermostat. Use 30 psi
(207 kPa) supply through a positioning switch so
pressure can be fully variable.
2. Determine the current change over point. Turn the
cooling dial so that the cooling and heating control
pressures are different. Then note the changeover
point on the control gauge as the supply pressure
changes.
Sensitivity Adjustment
The factory thermostat sensitivity setting is approximately
2.5 psi/F (31 kPa/C). To change the sensitivity, use a flat
blade screwdriver to carefully move the sensitivity slide
(Figure 3) to the desired position as follows:
3. Place an Allen wrench in the opening of the
thermometer assembly (Figure 3) to adjust the
changeover adjustment screw as follows:
Graduation closest
to the rigid end of
the bimetal element
4 psi/F (50 kPa/C)
Graduation closest to
the minimum (MIN) end
of the bimetal element
1 psi/F (12 kPa/C)
a. If the changeover is too high, turn off the supply
pressure and rotate the changeover adjustment
screw clockwise. One turn decreases the
changeover point by about 3 psi (20 kPa). Turn
on the supply pressure and recheck to verify the
new changeover point.
NOTE:
If the thermostat sensitivity is adjusted,
recalibrate the thermostat.
b. If the changeover is too low, turn off the supply
pressure and rotate the changeover adjustment
screw counterclockwise. One turn increases the
changeover point by about 3 psi (20 kPa). Turn
on the supply pressure and recheck to verify the
new changeover point.
Thermostat Calibration
The thermostat is factory calibrated to a control pressure of
7.5 psi (52 kPa) when the set point and the ambient
temperature are both at 72°F (22°C). No adjustments are
required if these settings are appropriate.
If the thermostat has been tampered, the sensitivity
changed, or it is out of adjustment, use the following
procedures to recalibrate the instrument.
The output pressure test port (Figure 4) is accessible
without removing the thermostat cover through the 8th
opening:
•
For TH192 HC thermostats, the port is on the left side.
CAUTION:
If you use the wrong test port, thermostat
damage can occur and result in
replacement of the device.
Figure 3. TH192 HC Thermostat Details.
Cooling Calibration
1. Remove the cover using the calibration tool.
Verify that the room temperature is between 70 and
80F (21 and 27C).
2. Verify that the supply pressure is 18 psi (124 kPa).
Set the cooling dial to the room temperature by turning
the exposed adjustment knob or using a hex key. Allow
the thermostat to stand for about five minutes to adjust
to the new setting.
