Instructions for the Robertshaw Thermostat

Robertshaw is a manufacturer of thermostats, zone controls, valves, timers, and other electronic HVAC control components. Robertshaw residential thermostats are user-programmable climate control devices that operate your home's heating and air conditioning systems. Factory programmed Energy Star temperature set points allow you to use your thermostat as soon as it's installed. If the pre-programmed set points don't meet your heating or cooling needs, customize the thermostat's programming schedule in minutes.

Step 1

Press and release the "Set" and "Prog/Man" thermostat buttons simultaneously to access the clock and calendar programming mode. Press the "Up" or Down" arrow buttons until the on-screen clock reflects the correct current time; press "Set." Use the "Up" and "Down" buttons to highlight the desired day of week indicator and press "Set;" select "1" for Monday, "2" for Tuesday, "3" for Wednesday, "4" for Thursday, "5" for Friday, "6" for Saturday, or "7" for Sunday.

Step 2

Adjust the temperature differential to the desired value using the "Up" and "Down" arrow buttons; press "Set." Follow the same procedure to set the second temperature differential when it appears on the digital display screen. Programming the desired temperature differential prevents the thermostat from cycling on too often. Robertshaw thermostats are factory programmed to switch on whenever the temperature in the room changes by just one degree.

Step 3

Highlight the desired residual cool option and press "Set;" the residual cool feature allows you to run the fan for an additional 30, 60 or 90 seconds. Use the residual cool feature to run the fan after the compressor shuts off in cooling mode.

Step 4

Move the "Cool/Off/Heat/Em" switch into the appropriate position to select the desired operating mode for your Quick Set program. Hold down the "Set" button, followed by the "Down" arrow button, and then let go of both buttons simultaneously. Use the arrow buttons to adjust the start time for the morning program segment when the "Morn" indicator appears; press the "Set" button. Follow the same procedure to set the start times for the "Day," "Eve," and "Nite" program segments. The Quick Set feature allows you to set a single heating or cooling program and use it for all seven days of the week.

Step 5

Use the "Cool/Off/Heat/Em" switch to select the desired operating mode when programming each day of the heating or cooling schedule individually. Press "Set" to access the programming screen. Highlight the desired day of week indicator using the arrow buttons; press "Set." Select the program segment that you want to modify and press the "Set" button. Press the arrow buttons until the desired start time for the selected segment is shown on the display screen; press "Set." Repeat this step to specify the start times for the remaining segments or to program the heating or cooling schedule for subsequent days.

Step 6

Move the "Fan/Auto/On" switch into the "On" position to run the fan continually or "Auto" to run it only when the thermostat is running an active heating or cooling program. Use the "Cool/Off/Heat/Em" switch to select between the "Heat" and "Cool" operating modes.

Step 7

Press the "Prog/Man" button until the "Prog" indicator appears on the digital display screen to activate your scheduled thermostat programming.
