Target Superheat (TSH)
Compare target superheat (TSH) to actual
superheat (SH) when charging fixed orifice
air conditioning systems. TSH is continually
calculated from indoor wet bulb (IDWB) and
outdoor dry bulb (ODDB) temperatures.
IDWB: By default, this is a manually set value of 60.0°F.
For a live measurement, assign the optional model JL3RH wireless
psychrometer (page 26).
ODDB: By default, this is the live measurement of the ODDB
thermocouple jack. If you prefer a static measurement, assign a
manual value (page 27).
1. Connect the included type K bead thermocouple to the ODDB
thermocouple jack. Use the alligator clip to locate the bead in a
shaded area of the condenser to measure the temperature of air
entering the condenser.
2. Press VIEW until ODDB is displayed to verify the measurement.
If you changed ODDB to a manually set value, it will be used to
calculate TSH but will not be displayed.
3. Measure IDWB after the lter, just in front of the indoor coil. If
a psychrometer is assigned, you can press AIR until wet bulb is
displayed to verify the measurement.
4. Press VIEW until TSH is displayed.
