IMPORTANT SAFETY INFORMATION

WARNING:

• Always turn off power at the main power source by unscrewing fuse or switching circuit breaker to the off position before installing, removing, or cleaning this thermostat.

• Read all of the information in this manual before programming this thermostat.

• This is a 24V AC low-voltage thermostat. Do not install on voltages higher than 30V AC.

• All wiring must conform to local and national building and electrical codes and ordinances.

• Do not short (jumper) across terminals on the gas valve or at the system control to test installation. This will damage the thermostat and void the warranty.

• Do not connect ground to any terminal in this unit.

• This thermostat is equipped with configurable automatic compressor protection to prevent potential damage due to short cycling or extended power outages. The short cycle protection provides up to a 5-minute delay between heating (heat pump only) or cooling cycles to prevent the compressor from being damaged.

• Do not switch system to cool if the temperature is below 50°F (10°C). This can damage the cooling system and may cause personal injury.

• Use this thermostat only as described in this manual.

About this guide: This User’s Guide deals with the basic display and programming features of this thermostat. It is not an exhaustive technical guide for every application and combination of heating/cooling equipment and controls that might be connected to the thermostat.

NOTE: In many cases the installer made the initial setup of your thermostat. That was based on your preferences and the characteristics of your heating/cooling system. Our User’s Guide gives information allowing you to make basic modifications for your home environment at any time.

CHOOSE HEATING/COOLING

To choose a mode (of operation), select Mode.

There are five possible operating modes:

Off – The heating/cooling systems are turned off, and will not operate. Heat – The heating system is activated. The main screen displays the heat icon ( ). Cool – The cooling system is activated. The main screen displays the cool icon ( ). Auto Changeover – Either heating or cooling will be activated to maintain the temperature

setpoint. The main screen displays the letter A next to the or .

NOTE: Auto Changeover will be displayed only if activated in System Settings. Emer – Emergency heat is activated. (This choice is available only when 1st stage Heat is set

as Heat Pump.) The main screen displays a small letter E next to the .

Note: Emer will not automatically energize on the 9701i2. You will need to manually select it from the Current Mode menu. Note: Balance points are not an option when an outdoor sensor is installed with the 9701i2.

When should I select Emergency Heat?

If your heat pump is not adequately providing heat, you can bypass it by selecting Emergency (heat) until the heat pump can be serviced. In some installations, your thermostat may indicate a problem with the heat pump by displaying a message (on the main screen) underneath the temperature. You may also want to select Emergency (heat) when the outdoor temperature drops below freezing since the heat pump is very inefficient at low temperatures. See Balance Points (page 20) for other options.
