Differential
The differential is the temperature difference
between the moment the Stage 1 start run-
ning in timer mode (stage 1 ramping) and
the moment they run continuously. Refer to
the diagram in section 6.2.2. The differen-
tial can be adjusted between 0.5°F and
20.0°F (0.3°C and 11.1°C).
Accessible if the ramping option is enabled in the
Installation Setup (section 4.5).
Timer
If timer-based relays are assigned to some
fan stages (sec. 4.8), set the On Time and
the Off Time of each timer-based relay.
These On/Off Times can be adjusted from 0
to 15 minutes in increments of 15 seconds.
