Non-Programmable Thermostats

A non-programmable thermostat maintains a single, manually set temperature rather than following a programmed schedule. These thermostats are a straightforward replacement option for households and businesses that prefer manual control over automated scheduling.

Furnace Part Source carries a range of non-programmable thermostats for residential and light-commercial HVAC systems, including basic digital models and higher-end Wi-Fi-connected thermostats that can also operate in non-programmable mode.

Common Non-Programmable Thermostat Types We Carry

Common thermostat types include:

  • Digital non-programmable thermostats for straightforward single-setpoint control.
  • Snap-action mechanical thermostats for simple, low-voltage heating and cooling systems.
  • Line-voltage thermostats for electric baseboard and radiant heating applications.
  • Wi-Fi thermostats with non-programmable mode for remote access without a fixed schedule.

How to Find the Right Non-Programmable Thermostat

Before ordering, check your existing thermostat's part number, voltage, and the number of heating and cooling stages it controls (such as 1 heat/1 cool). Confirm whether your system uses low-voltage (24V) or line-voltage wiring.

For best fit, compare:

  • Original thermostat part number
  • Voltage, such as 24Vac or line voltage
  • Heating and cooling stages supported
  • Compatible system type, such as conventional, heat pump, or electric heat

Non-Programmable Thermostat FAQs

What is the difference between a programmable and non-programmable thermostat?

A programmable thermostat follows a preset schedule with different temperatures at different times, while a non-programmable thermostat maintains one manually set temperature until it is changed.

Can a Wi-Fi thermostat be used in non-programmable mode?

Yes. Many Wi-Fi-enabled thermostats can operate in a simple, non-programmable mode while still offering remote access through a smartphone app, in addition to full scheduling if desired later.

How do I know if my system needs a 1-stage or 2-stage thermostat?

Check your existing thermostat's rating (such as 1 heat/1 cool) or your furnace and air conditioner's documentation to confirm how many heating and cooling stages your system uses.

Are line-voltage and low-voltage thermostats interchangeable?

No. Line-voltage thermostats are used with electric baseboard or radiant heat and are wired differently than low-voltage (24V) thermostats used with most central furnace and air conditioning systems.
