differential. (The factory setting is 3 Celsius degrees, or about 5 Fahrenheit
degrees.) To change the differential:
Hold the SET button for 5 seconds. P0 will be displayed. * Press the ▲button
once to change the display to P1, then press SET again. The present differential
temperature will be displayed. Use the ▲ and ▼buttons to set the desired
differential. The display will return to displaying system temperature after a few
seconds; the new differential temperature has been stored.
For your convenience, here are some Fahrenheit temperatures and their Celsius
equivalents, rounded to the nearest whole degree:
75F = 24C
80F = 27C
85F = 29C
90F = 32C
95F = 35C
100F = 38C
*Pressing the ▲ or ▼ buttons again will cycle the display through the following
codes: P1, P2, P3, P4, P5, P6, and back to P0. Many of these codes refer to
parameters used in heating and refrigeration systems, not in cooling systems.
Should any be adjusted accidentally, restore them to their factory settings:
P0 – C (for “cooling”)
P1 – Desired differential, set as described above
P2 - 110
P3 - -50
P4 - 0
P5 - 0
P6 – Off
