FAQs

  • The number of stages refers to the number of heating or cooling sources that can be controlled by a single thermostat. For example, if a system contains baseboard heat, a hot air system, and air conditioning then there are two heating stages, and one cooling stage. In this example, a thermostat that can control two-heat and one cool stage should be selected. It is important to note that if you have auxiliary heat (or backup heat), that counts as a second heating source. 2H/2C means the thermostat has two heat and two cooling stages. You can purchase a thermostat with more heating or cooling sources available than what you will use, but you cannot purchase a thermostat with fewer stages than what you have. For example, if you have two heating stages and one cooling stage, a 2H/2C thermostat is fine, but a 1H/1C thermostat will not work.
  • Programmable thermostats offer a high level of control. These units are highly energy efficient and allow you to save money on heating and cooling bills. For example, if no one will be in a given space from 9am to 5pm, a programmable thermostat can be set to lower the temperature at 9 am and bring it back up at 4:30pm, so the space reaches a comfortable temperature before you return. In contrast, a non-programmable thermostat may either be left on during this time period, wasting energy and money, or left off, meaning that you get home to an uncomfortably hot or cold room.
  • Honeywell Thermostats are the best selling thermostats on SupplyHouse.com. Honeywell is followed by White Rodgers and Robertshaw. These are all well known manufacturers that produce high quality, dependable thermostats.
  • The thermostats on this page are listed in order of popularity based on the number of units sold.

Articles

  • A thermostat is the interface between you and the heating and cooling systems in your home. Through your thermostat, you are able to control when specific rooms should be warmer or cooler and make sure that each room is comfortable for you. A wide variety of thermostats are available including Honeywell thermostats, programmable thermostats, non-programmable thermostats, and more.

    There are many factors to consider when deciding which thermostat is right for you. The main differences are programmability, the applications they are used for, number of stages, user interface, mount, voltage, changeover type and ability to work with sensors.

    Programmability
    Programmable thermostats save energy, save you money and maximize comfort based on your unique schedule! They typically have four setpoints, allowing you to set different temperatures for the morning, daytime, evening and over night. Most programmable thermostats can operate in a non-programmable mode if you choose not to set a program. A non-programmable thermostat's settings must be manually changed for temperature and on/off functionality.

    Application Type
    Thermostats vary by the different types of heating and/or cooling units they control.
    Heat Only - works only with a single heating source.
    Cool Only - works only with a single cooling source.
    Single Stage Heat/Cool - controls one heating source and one cooling source.
    Multi-Stage Heat/Cool - controls multiple heating and cooling sources.
    Electric Heat/Line Voltage - controls electric baseboard and electric heaters.
    Heat Pump - used in heat pump applications, such as air source heat pumps and ground so.urce heat pumps.
    Fan Coil - work with fan coil units, such as unit ventilators.
    Millivolt - used to regulate systems that utilize a pilot light rather than an electrical circuit, such as a gas-fired water heater.

    Stages
    This refers to the number of heating or cooling sources that may be controlled by a single thermostat. For example, if a system contains baseboard heat, a hot air system and air conditioning, then there are two heating stages and one cooling stage. In this example, a 2 heat/1 cool thermostat should be installed. Note: If you have auxiliary heat (backup heat, such as a fan coil or baseboard), that counts as a second heating source. The number of stages may be written in several different ways. The most common are 2H/1C or 2 Heat/2 Cool; both mean that there are two heat sources and one cool source. The number of stages can vary from single heat or single cool up to 4 Heat/3 Cool on a single thermostat.

    User Interface
    Thermostats are operated using a digital touchscreen, buttons with a digital screen, or simple mechanical dial. The most popular touchscreen thermostat on our website is the Honeywell TH8110U1003.

    Voltage
    Thermostats run on either line voltage or low voltage. The easiest way to tell if you need a line or low voltage thermostat is to look at the wire. If it's a very thin wire (like a doorbell or speaker wire), you'll need a low voltage thermostat. If it's a heavy wire, you'll need a line voltage thermostat.

    Changeover Type
    Thermostats either have automatic changeover or manual changeover. Thermostats with auto changeover switch from heat to cool automatically depending on the indoor temperature, while thermostats with manual changeover will remain on either heat or cool until you change it.

    We offer a wide selection of Honeywell, White Rodgers, Robertshaw, Lux, Wirsbo, and Tekmar thermostats.
