A two-way thermostat can set the temperature as low as 4° and as high as 99°. When using a CP-290 or FireCracker (CM-17) interface, many temperatures are not supported in this range and Thinking Home will only offer temperatures that can be used.

Two-way thermostats can also report information to the Thinking Home software. The Remote Control window can display the complete status of the two-way thermostat when selected. This information is not available when using a CP-290 or FireCracker (CM-17) interface.
