BLOWER PERFORMANCE SPECIFICATIONS
21
There are dual 7-segment LED's adjacent to the selection
dipswitches. The airflow rounded to the nearest 100 CFM,
is displayed on the dual 7-segment LED's. The CFM dis-
play alternates with the operating mode.
Example:
If the airlfow demand is 1230 CFM, the LED's will display
12. If the airflow demand is 1275 CFM, the LED's will dis-
play 13.
Note:
Continuous fan speed is selectable on dip switches
5 & 6. Choices are 25, 50, 75, and 100 % of max CFM.
Circulator Blower Speed Adjustment Switches
Note:
The optional usage of a dehumidistat allows the
furnace’s circulator blower to operate at a slightly lower speed
(85% of desired speed) during a combined thermostat call
for cooling and dehumidistat call for dehumidification. This
can be done through an independent dehumidistat or through
a thermostat’s DEHUM terminal (if available). This lower
blower speed enhances dehumidification of the conditioned
air as it passes through the AC coil. For proper function, a
dehumidistat applied to this furnace must operate on 24
VAC and utilize a switch which
opens on humidity rise.
