I have a gave furnace about 20 years old. I replaced a old thermostat
with a digital Honeywell. The old therm had two wires, red and white.
I connected the red to the RH terminal and the white to the W. My
question is do i need to leave the pre-installed jumper from RH to RC
in place? I have no a/c unit, just the furnace. Thanks.

Do the directions with the unit instruct you to remove
the jumper for a heat only system?

If not, don't do it.

If in doubt, call Honeywell's customer support number.
