4. 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 AHC 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 0°F to 40°F).
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).
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 Zone System, the balance points
only need to be changed at one thermostat. The Model 6504
will share the new settings with all connected thermostats.
