Ensure that the circuit breaker or fuse of the HVAC/heat pump system has not blown during installation. If the power
is not turned off first, or if the wire tip is touched during installation, the circuit breaker or fuse may blow.
5.11The thermostat cannot be heated or cooled?
If your thermostat does not turn on heating, cooling below the set temperature, or heating above the set temperature,
check the wiring first. Important: Before you start using a thermostat or heating and cooling system (HVAC/heat
pump), be sure to turn off the power supply to your HVAC/heat pump. Turn off the power supply to the circuit breaker
box or system main power switch. Confirm that the power is turned off before removing the device panel. You can
verify that the power is turned off by confirming that the screen is blank. Do not touch any exposed wire ends.
To troubleshoot your Amazon Smart Thermostat:
Confirm the system type, there are two types of thermostats: HVAC system and heat pump system
The basis for judgment is: after the heating system is running, return to the outdoor unit to check whether the device
is turned on and blow. If it is running and blowing, the system is a heat pump; Otherwise, it is a traditional system.
Check that the Alexa app is wired correctly.
In an HVAC system, there is a W connection in addition to R, Y, G, C.
In a heat pump system, in addition to R, Y, G, C, there are AUX and 0 / B connections.
Note: W and AUX share a single terminal
Move the wires to the correct terminals as needed.
If you moved any wires, reset the device. Then restart the setup and confirm that the selected system wiring is
correct.
5.12 What are the fan modes of the thermostat and how they work?
The fan is available in both automatic and manual modes
Auto mode (fan mode will also tum on/off synchronously when cooling or heating mode is on/off)
Manual mode (fan runs individually on/off, independent of cooling and heating modes)
