Another good thermostat from the Honeywell thermostat series worth considering is the RTH7500D.

The Honeywell RTH7500D generally possesses the same specifications as the RTH7600D. The only difference is it uses a soft-button, instead of a touch screen interface, for programming the settings.

This is perfect for those who do not want fingerprints on the screen or fear of a faulty touchscreen.

Benefits Of Owning A Honeywell RTH7500D

Clear Backlit Touchscreen Display

The Honeywell RTH7500D has a large backlit display with a soft-touch button interface that allows for easy programming. Its green backlight also allows you to read your programmed settings under low lighting conditions.

7-Day Programming

Daily customisation of your household’s heating and cooling schedule can be done for 7 days via the Honeywell RTH7500D. Within this heating and cooling schedule, you can further customise your settings differently for 4 periods within a 24 hour time frame.

Honeywell Smart Response Technology

This technology allows the continual and automatic adjustment of the pre-heating/cooling temperature of your home giving you precise comfort control within one-degree Fahrenheit of your programmed temperature.

Power Source

The Honeywell RTH7500D is powered by 2”AA” batteries.  For added convenience, this thermostat unit can also be run using power from your heating/cooling system, giving you the option of permanently eliminating battery changes.

Customer Reviews on Honeywell RTH7500D

I have read many customer reviews and summarised the pros and cons of the Honeywell RTH7500D below:

The Pros

Positive reviews about the Honeywell RTH7500D range from its clear and large backlit display, easy and intuitive programming setup and its elegant design. Its ease of installation, together with a clear installation and programming manual makes it a good inexpensive DIY project that you can consider installing to lower your carbon footprint.

The Honeywell Smart Response Technology ability to measure how fast your house is losing heat or warming up and then start up the system at the correct time to meet your programmed settings is also one of the pro that has been mentioned. Finally, Honeywell RTH7500D ability to maintain a steady temperature, and program 4 different temperature settings in 24 hours plus excellent after sales and technical support from Honeywell are other pros to why customers purchase this product.

The Cons

No dedicated backlight button and also isolated cases where customers still find the display to be too small or not bright enough are some cons that have been mentioned. The Honeywell RTH7500D has also been mentioned by some customers as not really compatible with heat pumps while installation as there are cases in which connecting wires do not match with each other. So to avoid this, it will be better to install the thermostat in conjunction with the Honeywell customer service on the line.

Other cons mentioned include the low temperature variance of the Honeywell RTH7500D that might result in unnecessary activation of the heat pump rather often in an effort to maintain the programed temperature that might cause you to lose more money on utilities. Besides that there are also isolated cases of bad customer service from Honeywell that could possibly be due to language barrier.

Product guide and information


The thermostat is backed by a one-year limited warranty that covers any defects in workmanship or materials from the date of purchase.
