KEY OPERATION

System key
Used to control the operating mode of the Performance PRO T8000 Series thermostats. The options available are dependent on System Type selected in Service Menu 110 (see Advanced Configuration in “Performance PRO T8000 Series Installation Guide”).

System modes are:

HEAT – Select for the system to operate in heating mode only. Only one setpoint is displayed.
COOL – Select for system to operate in cooling mode only. Only one setpoint is displayed.
AUTO – Allows system to control to both the Heat and Cool Setpoints. The system will automatically changeover between heating and cooling modes as room temperature varies. Cool Setpoint must always be greater than Heat Setpoint by the deadband value.
OFF – Disables all thermostat outputs; only zone temperature and time are displayed.
EMERGENCY (Em)– Emergency heat can be used when the Heat Pump cannot keep up with the heat load. Use Service Menu 110 (System Type 6 & 11) to enable.
Note: Deadband is the user-defined minimum difference between the Cool Setpoint and
Heat Setpoint (see Service Menu 380).
Fan key Used with two different menu options:
ON – Continuous fan operation.
AUTO – Fan is activated only when there is demand for heat or cool, with some exceptions.
Note: Several Service Menu options affect the fan operation (See Advanced
Configuration in the “Performance PRO T8000 Series Installation Guide.”)
More key Used to view more menu options. From the Default Display, press More to show more menu options that may be accessed by pressing the soft keys.

Note: Pressing ▲/▼ keys show the Override display unless Holiday mode is set.
Override key Used to create a temporary override of current setpoint temperature. Pressing Override will display the “Next” and “Done” options and the setpoint will begin flashing.
Temporary Override – The active setpoint is taken from setpoints defi ned in the Override menu. (In Home Display, “Override” fl ashes during the override time period if selected.)
The service Indicator Icon appears to notify the user that the remote temperature sensors are reading out of range.
Battery Indicator Icon appears only when the battery level is low and flashes when the battery level is critically low. Two AA alkaline batteries (2.6 – 3.1VDC) have an approximate 1-year life expectancy.
Keypad Lockout Icon appears if any type of keypad lockout is active. Keypad lockout blocks access to certain features of the thermostat. (See Service Menu 340 to enable Keypad Lockout).
