5. FAQ
5.1What is an HVAC thermostat?
An HVAC thermostat is a device used to control heating, ventilation, and air conditioning systems. It monitors indoor
temperature, humidity, air quality and other parameters, and adjusts the valves, fans, heaters, and coolers in the
HVAC system to maintain a comfortable indoor temperature. There are different types of HVAC thermostats,
including manual adjustment, programmable control, and intelligent self-learning, which can be chosen according to
the users needs and preferences.
5.2How does an HVAC thermostat work?
An HVAC thermostat typically consists of three main components: the sensor, controller, and actuator. The sensor is
usually installed indoors and is used to monitor parameters such as temperature, humidity, CO2 concentration, etc.
The sensor transmits the collected data to the controller.
The controller is the core component of the thermostat, which determines whether the indoor environment needs to
be adjusted based on the data transmitted by the sensor, and calculates the corresponding adjustment signal. In
manual adjustment thermostats, users can directly adjust the temperature through the knob or button on the
controller. However, in programmable and intelligent self-learning thermostats, users need to set the temperature
range, start and end time, and other parameters in advance. The controller will automatically adjust the temperature
based on the preset program.
The actuator is usually located in the heating, ventilation, and air conditioning system, including valves, fans, heaters,
and coolers. The controller adjusts the operation of the heating, ventilation, and air conditioning system through the
actuator to maintain a comfortable indoor environment temperature.
In summary, an HVAC thermostat uses the three components of sensor, controller, and actuator to work together,
achieving the function of automatic or semi-automatic adjustment of indoor environment temperature.

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)
5.13How does the infrared of the device detect the movement of the human body and what is the distance of
detection?
The infrared sensor detects a movement distance of within 50cm (including 50cm) of the human body.
If the device is powered by an AC power source, it will enter sleep mode after 3 minutes of no human operation and
can be awakened by a person approaching the device.
If the device is battery-powered, it will enter sleep mode and detection will require a person to touch the device.
5.14Can multiple thermostats be installed in one house?
Usually, one or more HVAC thermostats are installed depending on the size and layout of the house. Generally, one
HVAC thermostat is sufficient to control the entire HVAC system of a house. However, if the house has multiple
floors or independent HVAC systems, multiple thermostats may be necessary to control the temperature of each
zone or system.
5.15Can't air conditioners be set to a specific temperature directly? Why do we need to use an HVAC
thermostat to adjust the temperature?
Air conditioning is a device in HVAC system used to control indoor temperature and humidity. It absorbs heat from
the indoor air and discharges it outside to lower the indoor temperature. An air conditioning system typically consists
of a compressor, condenser, evaporator, fan, and control circuit. Air conditioning can be manually or automatically
controlled to regulate the temperature and humidity, providing a comfortable indoor environment.
A thermostat is a control device in the HVAC system used to control the operation of air conditioning or other heating,
ventilation, and air conditioning equipment to achieve the set temperature and humidity. A thermostat typically
consists of a temperature sensor and control circuit, and it can adjust the operation of air conditioning or other
equipment manually or automatically to ensure that the indoor temperature and humidity remain within the set range.
Advantages of a thermostat are:
1.It can control temperature more accurately: A thermostat can achieve constant temperature control based on
indoor temperature settings, which is more precise than air conditioning.
2.Energy saving: Using a thermostat can precisely adjust the indoor temperature according to demand, avoiding
waste of energy, and achieving energy-saving effect.
3.Easy installation: A thermostat can be relatively easily installed on the wall without major modifications.
Therefore, air conditioning and thermostat are two different parts of the HVAC system. Air conditioning is used to
control indoor temperature and humidity, while a thermostat is used to control the operation of air conditioning or
other equipment to achieve the set temperature and humidity.
