Detailed Explanation of User Options:
Temperature Differential
(User Option 1 and 2)
The differential setting is the temperature control range that your thermostat
will provide. The smaller the setting, the tighter your range of temperature
control and comfort will be. The 2nd stage differential is only for systems
with a second stage of heating (auxiliary heat).
