Solution
• Check if the built-in temperature sensor is disconnected from the thermostat circuit board or
damaged.
• Contact technical support.
• Check if the built-in temperature sensor is short circuited or damaged.
• Contact technical support.
Built-in temperature sensor detected a temperature that is too high.
• Verify that the thermostat wiring is connected correctly to the FCU or PTAC.
• Contact technical support.
Built-in temperature sensor detected a temperature that is too low.
• Verify that the thermostat wiring is connected correctly to the FCU or PTAC.
• Contact technical support.
• Check if the remote temperature sensor is disconnected from the thermostat terminals RS
and SC. If it is, rewire the remote sensor correctly and then power cycle the thermostat.
• Check if the remote sensor has malfunctioned or is damaged.
• Contact technical support.
• Check the remote temperature sensor wiring and check if thermostat terminals RS and
SC are shorted. If they are, rewire the remote sensor correctly and then power cycle the
thermostat.
• Check if the remote sensor is malfunctioned or damaged.
• Contact technical support.
Remote sensor detected a temperature that is too high.
• Verify that the thermostat wiring is connected correctly to the FCU or PTAC.
• Verify that the remote sensor is installed correctly in the room or duct.
• Contact technical support.
Remote sensor detected a temperature that is too low.
• Verify that the thermostat wiring is connected correctly to the FCU or PTAC.
• Verify that the remote sensor is installed correctly in the room or duct.
• Contact technical support.
• Check if the pipe temperature sensor wiring is disconnected from thermostat terminals PS
and SC. If yes, re-wire the pipe sensor correctly and then power cycle the thermostat.
• Check if the pipe sensor is malfunctioned or damaged.
• Contact technical support.
• Check the pipe temperature sensor wiring and check if thermostat terminals PS and SC are
shorted. If it is, rewire the pipe sensor correctly and then power cycle the thermostat.
• Check if the pipe sensor has malfunctioned or is damaged.
• Contact technical support.
Pipe sensor detected a temperature that is too high.
• Verify that the pipe sensor is installed correctly in the pipe.
• Contact technical support.
Pipe sensor detected a temperature that is too low.
• Verify that the pipe sensor is installed correctly in the pipe.
• Contact technical support.
