TH7000 Series
Special functions
Shaded areas below apply only to TH7220.
Auto Changeover (Setup Function 0300): When set to Auto, the thermostat automatically selects heating
or cooling depending on the indoor temperature. Heat and cool settings must be at least 2 degrees apart. If
function 0380 is set to On, the heat and cool settings must be at least 5 degrees apart.
Remote Sensor (Setup Function 0340): If an optional outdoor sensor is installed, the thermostat can
display the outside temperature. If an optional remote indoor sensor is installed, the thermostat will display
the temperature at the sensor location (the internal sensor in the thermostat is not used).
Adaptive Intelligent Recovery (Setup Function 0530): Allows the thermostat to “learn” how long the
furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached
at the scheduled time.
Compressor Protection (Setup Function 0580): Forces the compressor to wait a few minutes before
restarting, to prevent damage. During this time, the message “Wait” flashes on the display.
Heat Pump Temperature Lockout (with fossil-fuel backup): If the thermostat is installed with an optional
outdoor sensor, you can select a compressor lockout temperature (Function 0350). When the outdoor temperature is below the lockout temperature, only the auxiliary heat operates. When the outdoor temperature
is above the lockout temperature, only the compressor operates.
Heat Pump Temperature Lockouts (with electric heat backup): If the thermostat is installed with an
optional outdoor sensor, you can select a compressor lockout temperature (Function 0350) and/or an auxiliary heat lockout temperature (Function 0360). When the outdoor temperature is below the compressor
lockout temperature, only the auxiliary heat operates. When the outdoor temperature is above the auxiliary
lockout temperature, only the compressor operates. If the outdoor temperature is between the compressor
and auxiliary lockout temperatures, both the compressor and auxiliary heat can operate.
