Installation
this digital thermostat. As config-
ured at the factory, this thermostat
will maintain an accurate tempera-
ture. No further adjustment is
necessary, although you can use
these menu items to customize the
performance of the thermostat to
your requirements.
The adjustment range for HEATING
is from 1 to 40 (9 to 40 for heat
pump). The factory preset is 5 (13
for heat pump). The adjustment
range for COOLING is from 9 to
40. The factory preset is 12 (13 for
heat pump). The cooling will not go
below 9 because compressors
require a longer cycle. The adjust-
ment range for AUXILIARY (heat
pump only) is from 1 to 40. The
factory preset is 6.
The chart below shows how this adjustment range affects thermostat
performance.
HEATING COOLING
Anticipation Value Cycle Length Differential Temperature Cycle Length Differential Temperature
Shorter 0.4–0.6 F (0.2–0.3 C) N/A 1–8 N/A
Longer Shorter 9–20 0.6–1.0 F (0.3–0.6 C) 0.6–1.0 F (0.3–0.6 C)
Hydronic Longer 21–40 1.0–1.6 F (0.6–0.9 C) 1.0–1.6 F (0.6–0.9 C)
These numbers are approximate and represent operation with a typical
system. Actual temperature differentials and run times may vary widely
based on your building and equipment, as well as outdoor temperature
conditions.
