Six dip switches select Speed values for heat, cool, fan and dehumidification blower speeds (see the CFM
Tables).
Blower On and Off Delays
Four Heat blower on and four blower off delays are selected by two dip switches for each function. Refer to
Table 1 for specific delay values.
Speed Selection values
Three dip switches select 8 cooling speeds. Dependant fan, and dehumidification speeds are selected by
the same switches, their tabular values are enacted when their function is called.
Three additional dip switches select 8 heating speeds which are enacted when heat is called. This allows
independent selection of heating and cooling capacity parameters. See the CFM Tables for speeds.
F. CFM TABLES
The following tables contain blower speed settings and their respective air flowrates for the ECM blower motor.
To change air flowrates from that of the shipped settings, use the respective SW1 dipswitch on the furnace’s
integrated control board (see Figure 2).
