5.0 Star Rating: Outstanding
The RobertShaw RS-9405 solved my problem. First of all, its minimum temperature is 45 degrees F, well below the 53 degree minimum of my physical mercury thermostat that I had used before. That alone is a savings of 100 gallons of propane. However, this thermostat has a back up of turning on the stove (even if the batteries are depleted or missing) by a physical switch at 40 degrees. It is its own back up system!!! This is a great thermostat and it is very easy to install, even on my millivolt system. Happy camper....
4.0 Star Rating: Good
The thermostat was easy to install and works well. We are pleased with the product.
The Robertshaw RS-9405 Digital Non-Programmable Thermostat is compatible with gas, electric and millivolt systems. It is a single-stage thermostat, meant for single-stage heating systems.

An excellent feature on the Robertshaw RS-9405 digital, non programmable thermostat is the front loading battery door that gives you no-hassle access to the batteries. Also, the LCD display is one of the largest in the industry and up to 80 percent larger than competitive models. It is also backlit, which makes reading the screen in a dark room incredibly easy.

Maintain your optimal comfort level with the RS-9405 single-stage thermostat. It has a fully adjustable differential to increase comfort. It also has automatic compressor short cycle protection which is a system safeguard that reduces the damage to HVAC equipment over time.

Low temperature freeze protection on the Robertshaw RS-9405 protects pipes from freezing by turning on the heat if the temperature drops below 40 degrees Fahrenheit. Fast and easy installation is facilitated by the quick wire terminal block. There are sturdy wire clamps and no wrap around of screws. The positive-off switch ensures that the HVAC system shuts down and a 2 year warranty is included.
