Emerson 1F97-391 Thermostat User Manual

Before turning power on to the system,
the jumpers on the back of the
thermostat must be configured to
operate correctly with the system
equipment.
This thermostat is configured from the
factory to operate a standard fossil fuel
(gas, oil, etc.), forced hot air system
with a single stage air conditioning
compressor and fan. This is the correct
configuration for any system that
DOES NOT require the thermostat to
energize the fan on a call for heat.

A remote sensor can be used with this
thermostat. To use a remote sensor,
jumper W922 must be clipped (see fig.
10) and the REMT SEN option in the
configuration menu must be set to ON.

If you have an electric heat or other
system that REQUIRES the thermostat
to control the fan, find and cut the
jumper lead labelled W914 (see fig.
10). This will allow the thermostat to
energize the fan instantly on a call for
heat. If you are unsure if the system
requires the thermostat to control the
fan, contact a qualified heating and air
conditioning service person.
