Do not check heating system
operation by jumpering thermostat
terminals at the primary control
such as the gas valve, zone valve,
or oil burner control. This damages
the thermostat, instead, jumper R
and W wires at the thermostat.
Move the system switch to HEAT
and the fan switch to AUTO.
Press key until the setting is about
10
°
F (6

ture. Heating should start and the
fan should run after a short delay
(immediately if fan operation switch
is set in E position).
Press key until setting is about 10
°
F
(6
°
C) below room temperature. The
