11 best heat only thermostat

A heat-only thermostat is a type of thermostat designed specifically for controlling heating systems. It falls under the category of Nonprogrammable thermostats and is used in HVAC (Heating, Ventilation, and Air Conditioning) systems.Here are some key points about heat-only thermostats:

  1. Function: Heat-only thermostats are responsible for regulating the temperature of heating systems, such as furnaces, boilers, baseboard heaters, or radiant heating systems. They do not have the cooling or air conditioning control capabilities found in some other thermostats.

  2. Temperature Control: These thermostats allow users to set a desired temperature for their heating system. When the room temperature falls below the set point, the thermostat sends a signal to the heating system to activate and raise the temperature.

  3. Wiring: Heat-only thermostats typically have a simpler wiring setup compared to programmable thermostats or those designed for both heating and cooling systems. They usually have two or three wire connections, including a common wire (C-wire) and wires for heating control.

  4. Compatibility: Heat-only thermostats are suitable for homes or buildings where heating is the only HVAC system in use. They are not designed to control air conditioning or cooling systems.

  5. Display: Many heat-only thermostats have a basic digital or analog display that shows the current temperature setting and allows users to adjust it manually.

  6. Energy Efficiency: Using a thermostat to control heating can help improve energy efficiency by maintaining a consistent temperature and preventing the heating system from running excessively.

  7. Installation: Heat-only thermostat installation is usually straightforward, and many homeowners can perform it themselves. However, it's important to follow the manufacturer's instructions and ensure that the wiring is done correctly.

  8. Compatibility with Heating Systems: When choosing a heat-only thermostat, it's essential to ensure that it is compatible with your specific heating system. Different systems may require different types of thermostats.

  9. Maintenance: These thermostats typically require minimal maintenance beyond occasional cleaning and battery replacement (if applicable).

Heat-only thermostats are commonly used in residential and commercial settings where heating is the primary HVAC concern. They offer a simple and cost-effective way to control heating systems and maintain a comfortable indoor environment during cold weather.

Question: I followed the instructions to turn the backlight on. it worked first day but then stopped working. so i followed instructions again. why it stopped
Answer: Hello, for this Stroller Fan,the volts is 3.6V 5W. You can use the Clip On Fan by the 2200mAh lithium battery or the USB cable.

Cambond Customer Service Team
Question: can i use it in an rv with a 12 (2 wire) volt system
Answer: Hello, this unit doesn't need a rechargeable battery charger, the battery can be charged via the usb cable. And the 2200mah lithium battery is not equivalent to a aa. It is a 18650 lithium rechargeable battery. If further question, please feel free to contact us through Buyer-Seller Messaging: https://www.amazon.com/ss/help/contact/?_encoding=UTF8&marketplaceID=ATVPDKIKX0DER&ref_=v_sp_contact_seller&sellerID=AVKPYQ121BJBZ Have a nice day. Cambond Customer Service Team
Question: Does the display light up as shown in the description? That would make it easier to read
Answer: No, the battery it comes with is the only battery that will only fit in the fan. The fan works great, but I was disappointed that I wouldn't be able change out the battery once it died. Luckily i opened it up before our trip and noticed. Before our trip I bought a rechargeable battery pack to recharge the fan. :D

User questions & answers

Question: Does this have an on-off switch
Answer: This is just a simple thermostat that turns on when the temperature reaches the point at which you set it, and stays on until the temperature drops below that set point.
Question: Will this unit operate on a 12 volt RV electrical system without the aaa batteries installed? Will the display be readable
Answer: This means do not connect a variable speed control to the motor. The motor must run at full speed and only controlled by the thermostat.
Question: Can this be used for Gas Fireplace
Answer: Come on. At temperature range 60° to120°, you set the "fan on" to cool your whatever. HOWEVER! YOU DO NOT WANT your house fan on if there is a FIRE as it will create a chimney effect and make things exponentially worse so at 183° just before where stuff like wood starts to oxidize and combust (burn), it shuts off so you don't blame (and sue) them because YOU left a romantic candle burning and toasted your bedroom.
Question: Are you able to set the min and max temps, like a min of 50 degrees and max of 68 degrees
Answer: As the temperature increases in the attic the contact closes and the fan starts. So far mine works fine.

      Question: Can you remove the back plate and just use the 3" X 3" thermostat? It is going on top of a 1 X 4 trim board
      Answer: Hi there, The Honeywell CT30A1005 does not require the back plate with install. Hope this helps!
      Question: is this a 2 wire connection
      Answer: yes 2 wire, but be careful...no off switch even though picture may show one.
      Question: I have 3 wires,This thermostat has only connections for 2 wires.Can I still use it
      Answer: This will depend on your situation. If you are just trying to use it for turning on and off a heat source, then it should work just fine. Follow the instructions carefully. Even though you have 3 wires, I'm guessing one of the 3 is not being used. Follow the wire to the other end and see if all 3 wires are hooked up. If there are only 2 hooked up, those same 2 wires will be what you use at the stat. The stat is just like a light switch, just lower voltage. Power will come from your transformer, through the stat, then to the device control you want to turn on. If you have a unique situation and need more help, you can take some pictures and describe your application and send them to me at [email protected] and I will do my best to help you out.
      Question: will this work with a 750 mV system
      Answer: Didn't work for my Millivolt-only, no external power, Empire wall heater. Had to buy a Reed Switch to replace this. See my review 11/13/2020.
