4. CLHS1 (Single Stage) Blower Motor Speed Wiring
: TURN OFF THE ELECTRICAL POWER to the furnace before attempting to change blower
speed wiring.
A. The furnace is factory wired to the ignition control with standard heating and cooling speeds. When changing
motor speeds, simply switch the needed speed to either the heating or cooling terminal as applicable on the
module to obtain the desired CFM. The unused speeds should then be reconnected to the module in the "park"
positions.
B. The optional blower delay jumpers on the integrated control (Figure 13) are used to determine the length of the
heat delay–to-fan-off periods. The delay-to-fan-on period is preset and non-adjustable. The available options for
the delay-to-fan-off are as follows: 60, 90, 120 & 180 sec.
The factory default for optimum performance of the delay-to-fan-off period is 90 seconds.
