Installation, Operation & Application Manual

Amana 2246002 is a non-programmable electronic thermostat compatible with single-stage heating systems, heating/cooling systems, and heat pump systems; it works with gas, oil, or electric systems. It is also compatible as a master thermostat in zoned system applications. Other key features include:

  • Easy to Use: Set the room temperature and temperature differential with simple arrow buttons.
  • Freeze Protection: Protects pipes from freezing by automatically turning on the heat if the room temperature drops to 40°F, even if the batteries are dead.
  • Compressor Protection: Built-in compressor protection for air conditioners delays the A/C starting by 5 minutes after the system turns off.
