Allow time for the furnace to heat up and the fan to come on
before checking for heat at the register. Note that on most gas
and oil systems, the fan is not controlled by the thermostat, but
by another control, which may account for the delay.
Readjust according to instructions on pages 18 and 19.
Check that the wiring hole in the wall behind the wallplate has
been plugged with insulation to prevent drafts that might
adversely affect thermostat operation.
Be aware that it is normal for the current setting and display
temperature to differ occasionally.
Make sure the hole behind the thermostat is plugged with
insulation to help prevent drafts from adversely affecting the
thermostat operation.
The thermosat is factory-calibrated and cannot be adjusted.
