6. BALANCE POINTS (HEAT PUMPS ONLY)

This feature is only available when the thermostat has been configured to operate heat pumps (see SET THE CONFIGURATION DIP SWITCHES on page 6) and only when an outdoor temperature is available to the thermostat. Outdoor temperature can come from an ADHC or from an outdoor temperature sensor.

The low balance point is the outdoor temperature at or below which the thermostat will lockout the compressor(s) – only auxiliary heat will be used to satisfy heating demands. The high balance point is the outdoor temperature at or above which the thermostat will lockout the auxiliary heat – only compressor heat will be used to satisfy heating demands. Emergency heat operation is unaffected by the high balance point.

To change the balance points:

1.Make sure the thermostat is in the OFF mode.

2.Press and hold both the ▲ and ▼ buttons for 3 seconds.

– The display will show the ADV. SETTINGS MENU.

3.Use the ▲ or ▼ button to highlight “SET BALANCE POINTS” and press the SELECT button.

4.To cancel, press the BACK button. This will return you to the ADV. SETTINGS MENU.

5.To change the low balance point, press the ▲ or ▼ button to raise or lower the temperature value

(range is -10°F to 35°F and OFF).

6.To change the high balance point, press the SELECT button, then press the ▲ or ▼ button to raise or lower the temperature value (range is 40°F to 80°F and OFF).

7.To finish and return to the ADV. SETTINGS MENU, press the SELECT button after the value(s) have been set.

Important time saver: If the thermostat is installed as part of a Model 6504 Intelligent Zoned Comfort System, the balance points only need to be changed at one thermostat. The Model 6504 will share the new settings with all connected thermostats.

7. INPUT DEALER CONTACT INFORMATION

During thermostat operation, the two multi-function buttons are labeled INFO and MENU. When the INFO button is pressed, the thermostat will display the humidity and temperature sensed by the ADHC (if an ADHC has been installed), then the thermostat will display any monitor messages and dealer contact information. At installation, the contact information is blank and only the thermostat model number appears. You have the option of inputting this contact information with the name and number of your company. Three twenty (20) character lines are available for your company name and contact info.
