Setting functions and options

You can change options for a number of system functions. Available functions depend on the type of system you have. The functions, designated with four-digit numbers, along with available options are described on pages 3–6
This thermostat is pre-set for a single-stage heating/cooling system.
Setting function 0170 for a heat pump will adjust the default settings.

1. Press SYSTEM.
2. Press and hold the two blank keys on either side of the center blank key for approximately five seconds until the screen changes.
3. Cycle through the functions, and press st next to the four-digit number on the left.
4. As needed, change options for any function by pressing st next to the number on the right.
5. When you have made all changes, press DONE to save and exit.

Installer System Test

1. Cooling system 0 Compressor and fan turn off
   • 1 Compressor and fan turn on
   • 2 Second stage compressor turns on
   • 2 Fan system 0 Fan turns off
2. Fan turns on
3. Heating system 0 Heat and fan turn off
   • 1 Heat turns on (fan on if Function 0170 is set for heat pump, or if Function 0180 is set to “1”)
   • 2 Second stage heat turns on
4. Emergency heating system
   • 0 Em Heat and fan turn off
   • 1 Em Heat and fan turn on
   • 2 Second stage heat turns on (Auxiliary heat)

CAUTION: EQUIPMENT DAMAGE HAZARD. Compressor protection is bypassed during testing. To prevent equipment damage, avoid cycling the compressor quickly.

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 the circuit breaker and reset if necessary.
• Make sure the power switch at the heating and cooling system is on.
• Make sure the furnace door is closed securely.
• Make sure C wire is connected.

“Wait” appears on the screen

• The compressor protection feature is engaged. Wait 5 minutes for the system to restart safely, without damage to the compressor.

The button on the lower right of the screen is blank

• This button will remain blank unless the furnace filter change reminder is activated.

The red light is on

• If the thermostat is in Emergency Heat mode the red light is normal. It shows that the thermostat is in emergency heat mode.

The heating or cooling system does not respond

• Check the circuit breaker and reset if necessary.
• Make sure the power switch at the heating & cooling system is on.
• Make sure the furnace door is closed securely.
• If “Wait” is displayed, the compressor protection timer is on. Wait 5 minutes for the system to restart safely, without damaging the compressor.

The heating system is running in cool mode

• Check Function 0170: System Type to make sure it is set to match your heating and cooling equipment (see page 4).
