The Hunter 44155C thermostat, also known as the Set and Save Programmable Thermostat, can be used with various systems such as electronic pilot gas heating, fired boiler oil heating, electric air conditioning, and single-stage heat pumps. Programmable thermostats offer homeowners the ability to automatically adjust the temperature based on their schedule and preferences, resulting in cost savings for heating and cooling. Although the digital settings on the thermostat may initially seem confusing, once you become familiar with its operation, you can easily set or change the thermostat’s controls with just a few button presses.

Set the Date and Time

Press the “Day/Time” button, then use the up or down arrow to change the hour. When adjusting the hour, you will also have the option to select “AM” or “PM.”

Press “Day/Time” again to move to the minute setting. Use the up or down arrows to set the correct minute.

Press “Day/Time” once more to move to the day of the week setting, then use the up or down arrow to change the day. Press “Day/Time” again to save and exit the date and time setting mode.

Make sure to take note of the “AM” or “PM” indicator when setting the time and adjust the settings accordingly.

Manually Adjusting the 44155C Thermostat Temperature

Press the “Hold/Return” button until an icon appears on the screen if you want to permanently change the settings and override any previously set commands. If you only want to make a one-time change, skip pressing the “Hold/Return” button and proceed with the manual adjustment process.

Press and hold the up or down arrow for one second to initiate the manual adjustment process. Release the arrow button as soon as the display starts flashing.

Use the up or down arrow to select the desired temperature you want to achieve in your home.

Press “Hold/Return” again to exit the setting mode if you permanently overrode the settings. If you made a one-time change, you do not need to press anything to return to the normal display.

Setting Custom Temperature Programs

Move the system switch, located in the middle left-hand portion of the thermostat, to either “Heat” or “Cool” depending on whether you want to set a heating or cooling program.

Press “Program,” then adjust the time and temperature settings by using the up or down arrows to change the hour. Press “Program” to move to the minute setting. Use the up or down arrow to change the minute, then press “Program” to move to the temperature setting. Adjust the desired temperature by using the up or down arrow, followed by “Program.”

You can set custom temperatures for up to four programs per day, seven days a week. Once you set the hour, minute, and temperature settings and press “Program” for the first program, you will have the option to set the hour, minute, and temperature settings for the second, third, and fourth programs. You must set at least two programmed settings per day. The total time between two, three, or four programs must add up to 24 hours.

Reviewing and Controlling Programs

To review the programs you have set, simply press the “Program” button to scroll through each day and make the necessary adjustments.

If you need to control the programs for a different system, all you have to do is move the system selector switch to the opposite setting and repeat the same steps.
