BLOWER SPEED SELECTIONS
The furnace controls have five active quick connect termi-
nals for connecting the motor speed leads. These are:
1. FAN — motor runs on this speed when the thermostat
is in the “FAN ON” position.
2. LO HEAT — connect desired low heating speed.
3. COOL — connect desired cooling speed.
4. HI HEAT — connect desired high heating speed.
5. H/C (for heat/cool) — connect desired speed when
high heating and cooling speed are the same.
In addition to the active motor terminals, there are two
motor parking terminals (labeled M1 and M2) available for
placing any unused motor taps. All unused motor taps
should be connected to either M1 or M2. These terminals
(M1 and M2) will not be energized under any condition.
IMPORTANT: Do not connect any motor speeds to “HI
HEAT” and/or “COOL” if you use the “HEAT/COOL” termi-
nal.
If cooling speed and fan speed are desired to be the same,
this may be accomplished by not connecting “Y” to the in-
tegrated furnace control.
See selection titled “Field Selections – Dipswitches” for
setting the heating and cooling blower off delay times.
