Aube Technologies TH104PLUS Programmable Thermostat-FAQs
Are Aube thermostats easy to use?
Yes, Aube thermostats like the TH104PLUS are designed to be user-friendly. Many models come factory pre-programmed with a 7-day schedule, so you can start using them immediately and adjust settings as needed. The interface is straightforward, allowing easy temperature changes and switching between Fahrenheit and Celsius. Once installed, most homeowners find daily operation simple and intuitive without needing constant manual adjustments.
Are Aube thermostats compatible with all heating systems?
Aube thermostats are mainly designed for electric heating systems, especially electric baseboards and radiant floor heating. Some models are compatible with forced air gas or oil systems, but not all units work with every HVAC setup. It is important to verify voltage, amperage, and system type before purchasing. The TH104PLUS, for example, is typically intended for line-voltage electric heating applications rather than low-voltage central HVAC systems.
Who makes Aube thermostats?
Aube thermostats are manufactured under the Honeywell family of brands. Since 2009, Aube has been part of Honeywell, which is now known as Resideo in the home comfort market. This connection adds credibility, as Honeywell is a well-established name in thermostat and temperature control technology. Aube products focus especially on electric heating control solutions.
Does the Aube TH104PLUS support air conditioning?
The TH104PLUS is generally designed for electric heating systems and operates as a line-voltage thermostat. It is not typically used for central air conditioning systems that require low-voltage controls. Before installing, it is important to confirm whether your HVAC setup is heating-only or heating and cooling, as this model is primarily intended to control electric heat loads.
What is the ideal temperature setting for a home?
Most energy experts recommend keeping your home between 18°C and 20°C during colder months for comfort and efficiency. In Fahrenheit, this equals about 68°F. During warmer seasons, indoor temperatures between 23°C and 25°C are commonly considered comfortable. Ultimately, the ideal setting depends on personal preference, insulation quality, and humidity levels, but moderate settings help balance comfort and energy savings.
How should I correctly set a programmable thermostat?
A good starting point for winter is setting the thermostat to 68°F and adjusting slightly for comfort. With a programmable model like the TH104PLUS, you can lower temperatures while you are asleep or away and raise them before you return home. Small adjustments of one or two degrees at a time help maintain comfort while improving energy efficiency over time.
Do I need a professional to install the Aube TH104PLUS?
Because the TH104PLUS is a line-voltage thermostat rated for higher voltage systems, installation may be more complex than replacing a low-voltage thermostat. While experienced DIY users may handle installation, turning off the breaker is essential for safety. If you are unsure about wiring or dealing with 120V or 240V connections, hiring a qualified electrician is strongly recommended.
Should I set my thermostat fan to Auto or On?
For most heating systems, using the “Auto” setting is more energy efficient. In Auto mode, the fan runs only when heating is active, which reduces electricity use and wear on components. The “On” setting keeps the fan running continuously, which may improve air circulation but increases energy consumption. For electric baseboard systems controlled by the TH104PLUS, fan settings are typically not applicable.
Is 25°C too hot for a room?
A room temperature of 25°C can feel warm for many people, especially in winter. Comfort levels vary based on humidity, clothing, and activity level, but most guidelines suggest keeping indoor temperatures between 20°C and 23.5°C in colder seasons. In summer, 23°C to 25.5°C may feel comfortable. Maintaining moderate temperatures also helps reduce energy bills and strain on heating systems.
What are the main types of thermostats available?
There are three primary types of thermostats: manual, programmable, and smart. Manual thermostats require constant adjustment, while programmable models like the TH104PLUS allow you to set schedules in advance. Smart thermostats connect to Wi-Fi and can be controlled remotely through apps. Choosing the right type depends on your heating system, budget, and desire for automation and energy savings.
