Robertshaw 9600 Thermostat Details

The Robertshaw 9600 Thermostat is engineered to provide precise control over your home's heating and cooling, designed for 1 Heat / 1 Cool systems. This model boasts a versatile 5-2 day programmable schedule, allowing users to tailor their comfort across weekdays and weekends. It supports four distinct setpoints for weekdays—Morning, Day, Evening, and Night—and two for weekends, ensuring energy efficiency without sacrificing comfort. A unique aspect is its ability to maintain both summer and winter programming simultaneously, simplifying seasonal transitions with ease.

Operating the 9600 is straightforward, with intuitive controls for setting the time, day of the week, and preferred temperature differential. The temperature differential, initially set at 1° at the factory, can be adjusted by the user between 1 and 3 degrees. This adjustment fine-tunes system cycling frequency, preventing constant on-off events and prolonging equipment life. Users can also easily switch the temperature display between Fahrenheit and Celsius, catering to individual preferences and making it globally adaptable.

Power for program memory retention is supplied by two AA batteries, ensuring that your customized settings remain intact even during power outages. A low battery indicator prompts timely replacement, preventing loss of programming. Safety is paramount with the 9600, incorporating low temperature freeze protection, which mechanically activates the heat if the temperature drops to 40°F (4°C), even if batteries are drained or missing. Conversely, it provides automatic heating shutdown if the temperature exceeds 90°F (32°C) for additional system protection.

Installation requires careful attention to safety, starting with explicitly turning off power to the heating and cooling system. The manual provides clear, step-by-step instructions for replacing an existing thermostat, including crucial wire labeling to ensure correct connections. It emphasizes that this is a 24V AC low voltage device and warns against installation on voltages higher than 30V AC. Proper mounting location is also highlighted, recommending an inside wall, 4-5 feet above the floor, away from drafts, direct sunlight, or heat-generating fixtures to ensure accurate temperature readings and optimal performance.

Beyond its core programming, the thermostat offers useful functionalities like temporary program override, allowing brief temperature adjustments without altering the meticulously saved schedule. For complete manual control over temperature settings, a dedicated mode is available by pressing the PROG/MAN button. Furthermore, a convenient reset button located directly to the right of the display restores the thermostat to its factory preprogrammed conditions, providing a clean slate if needed. The comprehensive troubleshooting guide is an invaluable resource, addressing common symptoms such as the system not activating, frequent cycling, blank displays, or incorrect program following. This support ensures users can quickly diagnose and resolve most operational issues, maximizing their comfort and convenience.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Robertshaw 9600 Thermostat, and we answer them below.


My heating/cooling system is not turning on. What should I do?
First, check the wiring connections of your thermostat as per the installation guide. Also, inspect the fuse and replace it with a 2 amp Slo-Blo fuse if it has opened.

The thermostat seems to turn my system on and off too frequently. How can I fix this?
You can resolve this by increasing the temperature differential. This setting, adjustable from 1 to 3 degrees, determines how much the room temperature must vary from the setpoint before the system activates. Refer to the programming guide for adjustment instructions.

The display is blank, flashing, or constantly showing 'LO BAT'. What's wrong?
This indicates that the two AA batteries powering the program memory are low or drained. Replace both batteries immediately to restore full functionality and retain your programmed settings.

My weekend program is following the four weekday adjustment settings. Why?
Verify that the day of the week is set correctly in your thermostat's programming. Incorrect day settings can cause the thermostat to apply weekday schedules to the weekend.

The system fan does not operate properly or at all. What should I check?
Ensure the fan option switch on the thermostat's base is correctly set to either 'GAS' or 'ELEC' to match your furnace type. Refer to the installation section for its location and proper setting.

The time shown on the display is incorrect. How do I change it?
To change the time of day, press and hold the SET button, then press PROG/MAN simultaneously. Use the up/down arrows to adjust the time, then release the buttons.

My thermostat is not following the programmed schedule. What could be the issue?
Several factors can cause this. First, check if the thermostat is in MANUAL mode; if so, switch it to PROG mode. Verify that the program was set correctly for both HEAT and COOL positions, and ensure the AM/PM indicators for programmed time changes are accurate. Also, confirm the day of the week is correctly set.

How do I change the temperature display from Fahrenheit (°F) to Celsius (°C)?
To switch between Fahrenheit and Celsius, press and hold the SET button, then simultaneously press the up arrow. Release both buttons to toggle the display unit.

What is the temperature differential, and how can I adjust it?
The temperature differential is the degree difference from your set temperature at which the system will turn on. It's factory preset at 1° but can be adjusted from 1-3°. To change it, press and hold SET, then PROG/MAN simultaneously, then press SET again. Use the up/down arrows to modify the differential value.

Can I temporarily change the temperature without affecting my program?
Yes, you can use the temporary program override feature. Simply press the up or down arrow buttons to adjust the temperature. The thermostat will automatically revert to your programmed schedule at the next scheduled setting change.

How do I reset the Robertshaw 9600 Thermostat to its factory preprogrammed conditions?
To perform a factory reset, locate and press the RESET button. This button is typically found directly to the right of the display.

Is it safe to test the installation by shorting (jumping) across terminals on the gas valve or system control?
No, absolutely not. The manual explicitly warns against shorting across terminals. Doing so can damage the thermostat and will void your warranty. Always follow the prescribed testing procedures.

What is the purpose of the 5-minute delay during cooling system operation?
The 9600 has a built-in 5-minute delay on break for compressor protection. This delay prevents rapid cycling of the air conditioning compressor, which can cause damage to the unit and potentially lead to personal injury.
