NOTES
Wire specifications:
Use 18 to 22-gauge thermostat wire.
Shielded cable is not required.
[1] Power supply. Provide disconnect means
and overload protection as required.
[2] Remove jumper for 2-transformer sys-
tems.
[3] Optional 24 Vac common connection.
[4] Common connection must come from
cooling transformer.
[5] Use either O or B terminals for change-
over valve.
[6] Use a small piece of wire (not supplied) to
connect W and Y terminals.
[7] Set fan operation switch to Heat Pump
(see page 5) and configure system type
for heat pump (see page 6).
[8] L terminal sends a continuous output
when thermostat is set to Em. Heat.
Connect to Honeywell Home zoning pan-
els to switch the panel to Emergency Heat.
[9] Install field jumper between Aux and E if
there is no emergency heat relay.

Thermostat mounting
Set fan operation switch.
Fan operation settings (TH3110D only)
1. Align the 4 tabs on the wallplate
with corresponding slots on the
back of the thermostat.
2. Push gently until the
thermostat snaps in place.
3. Push excess wire back into the
wall opening.
4. Plug wall opening with non-
flammable insulation.
Gas or Oil: For gas or oil heating
systems, leave the fan operation
switch in this factory-set position.
(This setting is for systems that
control the fan in a call for heat.)
Electric or Heat Pump: Change
the switch to this setting for heat
pump or electric heat systems. (This
setting is for systems that allow the
thermostat to control the fan in a call
for heat, if a fan wire is connected to
the G terminal.)

Troubleshooting
If you have difficulty with your thermostat, please try the following
suggestions. Most problems can be corrected quickly and easily.
Display is
blank •Check circuit breaker and reset if necessary.
•Make sure power switch at heating & cooling system is
on.
•Make sure furnace door is closed securely.
•Make sure fresh AA alkaline batteries are correctly
installed (see page 2).
Heating
or cooling
system does
not respond
•Set system switch to Heat. Make sure the temperature
is set higher than the Inside temperature.
•Set system switch to Cool. Make sure the temperature
is set lower than the Inside temperature.
•Wait 5 minutes for the system to respond.
Temperature
settings do
not change
Make sure heating and cooling temperatures are set to
acceptable ranges:
•Heat: 40° to 90°F (4.5° to 32°C).
•Cool: 50° to 99°F (10° to 37°C).
“Cool On” or
“Heat On” is
flashing
•Compressor protection feature is engaged. Wait 5
minutes for the system to restart safely, without
damage to the compressor.
“Heat On” is
not displayed •Set the System switch to Heat, and set the temperature level above the current room temperature.
“Cool On” is
not displayed •Set the System switch to Cool, and set the temperature level below the current room temperature.
