BLOWER SPEED SELECTIONS
The UT Electronic Controls control boards have four quick con-
nect terminals for connecting the motor speed leads. These are:
1. FAN SPEED* — motor runs on this speed when the thermo-
stat is in the “FAN” position.
2. COOL — connect desired cooling speed.
3. HEAT — connect desired heating speed.
4. HEAT/COOL* — connect desired speed when heating and
cooling speed are the same.
5. If heating and continuous speed are the same, jump across
“FAN” and “HEAT” terminals.

INSTRUCTIONS FOR CHANGING
BLOWER SPEED
The blower motor is wired for blower speeds required for normal
operation as shown.
If additional blower speed taps are available (leads connected to
“M1” and “M2” on the electronic control), speeds may be changed
if necessary to fit requirements of the particular installation. Re-
connect the unused motor leads to “M1” or “M2.” Check motor
lead color for speed designation.
Heating speeds should not be reduced where it could cause the
furnace air temperature to rise to exceed the maximum outlet air
temperature specified for the unit.
!
CAUTION
DO NOT CONNECT ANY MOTOR SPEEDS TO “HEAT” OR
“COOL” IF YOU USE THE “HEAT/COOL” TERMINAL. DOING
SO WILL DAMAGE THE BLOWER MOTOR. UNUSED
MOTOR WIRE TAPS MUST BE CONNECTED TO PARKING
TERMINALS M1 AND M2 OF THE IFC, OR PROPERLY IN-
SULATED.
!
WARNING
DISCONNECT THE ELECTRICAL SUPPLY TO THE FUR-
NACE BEFORE ATTEMPTING TO CHANGE THE BLOWER
SPEED. FAILURE TO DO SO CAN CAUSE ELECTRICAL
SHOCK RESULTING IN SEVERE PERSONAL INJURY OR
DEATH.
