The Thermostat Temperature Sensor: Placement Matters
When it comes to home heating and cooling, the accuracy of temperature readings is crucial. A thermostat with a well-placed temperature sensor can ensure that your home is kept at the ideal comfort level. But where exactly is this temperature sensor located, and how does its placement impact your system's efficiency?
Types of Thermostat Temperature Sensors
Not all thermostats are created equal. Some have a temperature sensor built directly into the unit, while others require a separate remote sensor. Let’s explore these options and their implications.
1. Built-in Temperature Sensor
For basic, wall-mounted thermostats, the temperature sensor is often integrated directly into the thermostat itself. This design simplifies the installation process. However, its placement can still impact the accuracy of temperature readings. Typically, such sensors are within 10cm of the thermostat's controller.
The low voltage thermostats, which operate on 24 volts, connect to the low voltage AC/heating system through either a three-wire or five-wire control setup with a common return. Each input corresponds to heat, cool, and fan control, ensuring precise management of your home climate.
2. Remote Temperature Sensor
For more advanced thermostats, a separate remote temperature sensor is often used. This sensor can be placed in a different location within the home, providing a more accurate representation of the room temperature. The remote sensor is then connected to the thermostat through wiring. This setup is particularly useful in homes with unique temperature distribution challenges.
Proper Placement of the Temperature Sensor
No matter whether the temperature sensor is built-in or remote, its placement is critical for accurate readings. Here are some guidelines:
Height and Position: The sensor should be placed about 5 feet high on a column or interior wall in a central location. This position ensures good air circulation and avoids common temperature distortion factors such as doors, direct sunlight, ceiling fans, air conditioning supply ducts, and any hot or cold equipment.
Avoid Disturbances: Placing the temperature sensor too close to supply ducts can cause temperature fluctuations as the heating and cooling system operates. Additionally, sealing the wall hole where the temperature sensor wires pass through is crucial to prevent air leakage, which can affect sensor readings.
