Fig. 21 – Example of Two-Stage Speed Furnace Control for VCA or

VCT Blower Motor

1. Enable two-stage thermostat on control board by:

a. For boards with DIP switches, turn SW1-2 on furnace control

ON, see

Fig. 21

b. For boards with 3 digit display, navigate to (

Htt

) and select

(

2st

), see

Fig. 21

. See furnace installation manual for additional

instructions.

2. Jumper R-W/W1 and R-W2 thermostat connections on control.

3. When main burners ignite, confirm inlet gas pressure is between

4.5-in. w.c. and 13.6-in. w.c.

4. Remove jumper across R-W/W1 and R-W2 thermostat connections

to terminate call for heat.

5. Turn furnace gas valve switch to OFF position.

6. Turn gas supply manual shutoff valve to OFF position.

7. Turn off furnace power supply.

8. Remove manometer and on some models remove pressure tap

fitting.

9. On some models, apply pipe dope sparingly to the end of inlet gas

pipe plug and install into unused end of 1/8-in. (3 mm) tee. Use a

small back-up wrench on tee when tightening gas inlet pipe plug.

Or, on some models, tighten set screw on inlet tower pressure tap

with a 3/32-in. hex wrench, see

Fig. 13
