NOTES:
1. MH and Res represent Manufactured Housing and Residential (modular home) applications, respectively
2. To comply with government mandated efficiency standards, speed settings with higher CFM values than listed in this table are not allowed
in Electric resistance heat only mode
Table 5. Maximum Allowable Heat Settings
The maximum heat rise at 0.4” w.c. (100 Pa) external static
pressure (ESP) for simultaneous Heat Pump and Electric
Resistance operation is 75°F (41.7°C). To determine the
blower minimum speed* for this mode operation, use the
calculation below; an example of E7E*-023* and a 4 ton
heat pump is also provided in both metric and imperial
calculations.
*
During a simultaneous Y and W call, the control board will output the highest of the two speeds, so the “blower
minimum speed” can be either dipswitches 1-4 (HEAT) or 5-8 (COOL). If calculated airflow does not coordinate to
an exact blower speed, select the next highest airflow setting.
