Heat Pump Thermostat Wiring Chart & Diagram

The following graphics are meant as a guide only. Always follow manufacturers instructions for both the thermostat and the HVAC system. Additional articles on this site concerning thermostats and wiring can help you solve your problem or correctly wire a new thermostat. Some HVAC manufacturers use other colors for additional control points and it is why we advise you to read the manufacturers instructions. These charts and diagrams only represent the basic system. It is possible your system is equipped with additional HVAC components such as a humidifier or electronic air cleaner. Depending on the manufacturer and the designer of the components will depend on how the additional components are wired or integrated into your system or thermostat.

The Basic heat pump wiring for a heat pump thermostat is illustrated above. It corresponds with the chart below to explain the thermostat terminal functions. Before uninstalling the old thermostat take a picture of the wiring with your cell phone before removing the wires. This way you have a reference. At the minimum draw a picture of it referencing the wires, wire color and what terminal the wire is attached to what terminal. The photo and the drawing reference can be used later to make sure you wire the new thermostat properly.

Humidifiers and Comfort – HVAC Healthy Living

Humidifiers and Comfort

Humidifiers and Comfort

Humidifiers and Comfort  – It’s winter time, and your skin and sinus’s are dry. Did you know that this condition not only extends to yourself and your health but also to your home? The furniture, doors, and other wood products in your home are all affected by the level of humidity.

Ever notice in the winter time the doors don’t close just right inside your home? Ever get static-shock when you touch something or someone? This is caused by dry air. The solution is a humidifier. There are many types of humidifiers from portable to fixed. The prices for these humidifiers also vary. Naturally the fixed will cost more and you will most likely have to hire a contractor to install it, but the humidifier will definitely make a big difference not only for your health, but also for your home.Proper Humidity Levels

Humidifiers and Comfort  – Summer Humidity

In the summer, a lot of the energy consumed by your air conditioner is used to de-humidify the air. In most geographical locations in the U.S. and Canada there is an abundance of moisture in the air. The process of heating your home in the winter time, especially for heat pumps, dries the air out in your home. It then becomes necessary to humidify the air (unless you choose to ignore it) to keep a comfortable level of moisture in the air. Ideally, you want the humidity level in your home to be around 30 to 50 percent. In the summer this is not a problem. In the winter it is a problem. This level of humidity will also help you feel more comfortable. If the humidity level in your home is high in the summer you will not feel cool. If the humidity level is low in the winter you will not feel warm when the thermostat is set at an average temperature. This will result in turning the thermostat up to compensate and you will use more energy to stay warm. A properly designed and installed system will keep the proper levels of humidity in your home.

Humidifiers and Comfort  – Dust, Dust Mites, Pollen, Viruses, Bacteria, and Humidity

Aside from the comfort factors of having the proper humidity levels in our homes, there is another aspect of having proper levels of humidity in the home. Humidity affects what is in our air also and this is why a humidifier is an integral part of a system that maintains optimum indoor air quality standards. Too much humidity promotes the growth of molds and mildews. Low humidity levels promote bacteria, viruses, and other organic and non-organic things that can be hazardous to our health. Below is a chart that will help you see that keeping the proper humidity levels in your home will also keep out things that can affect our health and our home.

Those people who have forced air systems I usually recommend having the whole house duct mount humidifiers installed. These are generally maintenance free except for a water panel that needs to be replaced on an annual basis. It will require the installation of a humidistat so that the proper amount of humidity is maintained in the dwelling. This system is automatic with no worries about manually filling up a pan or moving a large appliance like you have with the portable humidifiers. All you have to do is set the humidistat and change the water panel annually (or have a service technician do it when you have preventive maintenance done). Remember, humidity in your living and work space is important for your health. The are many different brands to choose from when selecting a whole house humidifier. Generally, Honeywell Whole house Humidifiers and Aprilaire Whole House Humidifier are good brands to choose from but there are others. Check with your HVAC Contractor for what they recommend for humidifiers.

Humidifiers and Comfort – Conclusion

Whether you have a Honeywell humidifier, Aprilaire humidifier, or other brand, remember there is required annual maintenance to your humidifier. Typically, humidifiers have water panels inside of them that some people refer to as humidifier filters. These humidifier filters as they are referred to treat the water that is channeled into the humidifier. This humidifier water filter needs to be changed at least annually to have the proper effect. Your HVAC contractor can arrange a maintenance agreement with you to maintain the humidifier and change the water filter so you do not have to worry about it.

Condenser Fan Motor

Condenser - Air Conditioner - Heat Pump Fan Motor

Condenser Fan Motor Inside the Condenser

The condensing unit fan is responsible for pulling air through coils of the condensing unit. They pull air through the condensing unit coils. It runs the gamut in horsepower ratings from low fractional horsepower in small residential units all the way up to 1 horsepower (and larger) 3 phase motors in large commercial HVAC units. It is usually direct drive to a propeller blade which creates the air flow. Its job it to move air. A specific quantity of air through the condensing unit coils so that a heat exchange process can take place and rig the condensing unit of the heat it absorbed indoors or in the case of the heat pump in heating mode to absorb heat from the outside air and send it inside. It is the process of refrigeration and all the components work together to achieve one result and that is to move heat from one place to another.

Duct Work and High Ceilings | HVAC Duct Work Systems

Duct Work and High Ceilings – I did not see any reference to my question and would appreciate a response as soon as possible, as due to medical situation, have to make a decision soon. We own an OLD house with 13′ ceilings in a large part of the home and 11″ ceilings in the LV/DR and BR. We are oscillating on where to place the ducts….Floor or ceiling. It appears to be counterproductive to me to put the duct work in the ceiling since it will have so far to go. We are looking for the most cost effective, not upfront cost but operating cost, solution. In addition, we are considering DF heat pumps. The house will need 2 or 3 to be zoned correctly. Please let me know about the duct placement and thank you for your help?

Air Conditioner Inverter Review | Heating and Cooling Efficiency

Air Conditioner Inverter Review

Many minisplit air conditioners and heat pumps use inverters for efficiency. Conventional split system air conditioner and heat pumps can now be purchased with inverters for ultra efficient heating and cooling.

Air Conditioner Inverter Review – Many minisplit air conditioners and heat pumps use inverters for efficiency. Conventional split system air conditioner and heat pumps can now be purchased with inverters for ultra efficient heating and cooling.

Inverter air conditioners came to the USA in the form of ductless mini-split air conditioners and were later expanded to ductless mini-split heat pumps. Inverter air conditioners and inverter heat pumps are considered the most efficient air conditioners and heat pumps available on the market for conventional systems and for air source air conditioners and air source heat pumps the inverter air conditioners and inverter heat pumps come close to matching the efficiency of geothermal heat pump systems. In fact some inverter air conditioners and inverter heat pumps beat some geothermal heat pump systems when matched up for efficiency. If it is impractical to drill a well or do trenching for a geothermal system and you want very high efficiency the next best thing is an inverter air conditioner or an inverter heat pump. Of course with any air source heat pump geographical considerations must take precedence as air source heat pumps are not practical in the northern climates for technical reasons unless they are specially engineered heat pumps for operation in the Northern climate region.
