Installation
Installation location recommendations
Thermostat should be mounted:
Do not mount thermostat:
• On an interior wall, in a frequently occupied space.
• Behind doors, in corners, or other dead air spaces.
• Approximately 5‘ above floor.
• In direct sunlight, near lighting fixtures, or other
appliances that give off heat.
• At least 18” from outside wall.
• Thermostat can be mounted to a vertical junction box.
• On an outside or unconditioned area wall.
• In the flow of a supply register, in stairwells, or near
outside doors.
• On a wall with concealed pipes or ductwork.

10/13/09 11:08:57 AM
Installation
Outdoor temperature sensor (optional)
• Install on side of building out of direct sunlight
(north side recommended).
Outdoor temperature can be measured by attaching an
8052 sensor to the S1 and S2 terminals. System setting
#05 (Remote sensor) is used to enable sensor.
• Mount above snow line.
Heat pump models can use the outdoor temperature to
effectively utilize the heat pump:
• Mount at least 3’ away from exhaust vents and
condensing lines.
• When the outdoor temperature is less than the Low
Balance Point, the heat pump will be locked out and
only auxiliary heating will be used.
• Do not route wires along 120 VAC lines.
• Maximum wire length is 300’.
• When the outdoor temperature is higher than the High
Balance Point, the auxiliary heating will be locked out
and only the heat pump will be used to provide heating.

Installation
Thermostat mounting
Power & Reset options
The thermostat is dual power. It can either be AC or
battery powered, or both (to provide backup power for
the clock). Batteries are optional if the thermostat was
connected to AC power when installed.
For heat pump models (8446, 8448HP, 8465, 8466HP)
24 VAC must be connected in order for the system fault
and emergency heat indicators to operate.
The thermostat has a memory backup that saves the
thermostat’s settings in case of a power interruption.
1. Remove the back of the thermostat, by pressing the
tab on the bottom of the unit.
The reset button located under the battery cover can be
used to reset the thermostat back to factory defaults.
The system settings will also be reset back to defaults.
2. Pull wires through the opening on the back of the
thermostat.
3. Position and level the back of the thermostat on wall
and mark the hole locations with a pencil.
4. Drill 1/4” holes & insert supplied anchors (drywall only).
5. Place back over anchors, insert and tighten screws.
6. Seal wire entry holes to prevent drafts affecting
temperature readings.

Thermostat Features
All 8400 series thermostats
• Large, clear, backlit display is easy to read – even
in the dark.
• Displays room temperature, temperature setting, and
optional outdoor temperature.
• Dual power option (Battery or 24 VAC).
• Front battery door access for fast, easy replacement.
• Built in compressor protection.
• Circulation fan mode for air cleaning.
• Water panel, dehumidifier, air filter, and HVAC
service indicators.
Programmable models only
(8463, 8465, 8466)
• Separately programmable weekday/weekend
schedules.
• Easy to use temperature control can override
program schedule at any time.
• Progressive recovery. Progressive Recovery feature
allows the thermostat to activate the heating and
cooling equipment prior to an event in order to reach
the desired temperature at the start of the next
scheduled event.
• System test mode.

Troubleshooting
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.
• If thermostat is battery powered, make sure fresh AA
alkaline batteries are correctly installed.
Temperature settings do not change
Make sure heating and cooling temperatures are set to
acceptable ranges:
Heating system does not respond
(“HEATING” appears on screen)
• Check for 24 VAC at the equipment on the secondary
side of the transformer between power and
common. If voltage is not present, check the heating
equipment to find the cause of the problem.
• Check for 24 VAC between the heat terminal (W)
and the transformer common. If 24 VAC is present,
the thermostat is functional. Check the heating
equipment to find the cause of the problem.
• Check for loose or broken wires between the
thermostat and the heating equipment.
• Heat: 45° to 90°F (7° to 32°C).
• Cool: 50° to 99°F (10° to 37°C).
