Honeywell FocusPRO TH5000 Series Operating Manual

To set the temperature, press the up or down arrow buttons on the thermostat's front panel until you reach your desired temperature. The setting will automatically save after a few seconds.
A blank display may indicate a power issue. Check that the thermostat is properly connected to the power source and that the circuit breaker is not tripped. You may also need to replace the batteries if your model is battery-powered.
To switch modes, press the 'System' button until you see the desired mode ('Heat', 'Cool', or 'Off') displayed on the screen.
Ensure that the thermostat is set to the correct mode and that the fan settings are appropriate. Check for any drafts or heat sources near the thermostat that might affect its readings. If the issue persists, recalibrate the thermostat or consult a professional.
Press the 'Set' button, then use the arrow buttons to adjust the time and temperature for each period (Wake, Leave, Return, Sleep). Once set, press 'Run' to save your schedule.
'Aux Heat' indicates that the auxiliary heating system is on. This typically happens when the primary heating system can't keep up with the demand, often during very cold weather.
To reset the thermostat, turn off the system and remove the batteries. Wait for about 10 seconds, then reinsert the batteries and turn the system back on.
Check the wiring connections between the thermostat and the HVAC system. Ensure that all wires are securely connected and not damaged. If the issue persists, consult the installation manual or a professional technician.
It's recommended to replace the batteries once a year or when the low battery indicator appears on the display to prevent power loss.
