15. rooms whose temperatures can fluctuate without discomfort to you Storage rooms for extra heated and extra cooled air can be important if you have other rooms that habitually draw high quantities of conditioning For example suppose you have a western facing room that requires near constant air conditioning during the summer Unfortunately if there are no other rooms in the house that require air conditioning the system won t start a cycle just for that room alone Remember that because of airflow requirements the system requires multiple rooms for a cycle Therefore if you have a room that s a designated storage room for extra cooling the system can initiate the cycle This usage scenario also applies to a room that require near constant heating in the winter Set a little used room to More for Extra Heat so that the system can initiate heating cycles more often 48 Room Priority Suppose in summer you let your house temperatures rise while you re at work Room Priority allows you to then focus air conditioning on those rooms you d liked cooled most quickly when you get home Likewise in winter you may allow house temperatures to drop during the day and then use Room Priority to heat the most important rooms first During extreme temperature conditions your HVAC equipment may struggle to keep all the rooms in the house at a comfortable temperature In this case for example in the summer you can focus air condition

60. t Your system can help you save energy in several ways The following suggestions are described in detail later in this manual e Use the widest comfort ranges possible Decrease the lower limits to use less heating and increase the upper limits to use less cooling e Divide your house into zones in which the rooms in each zone have the same usage pattern during the week Use wider comfort ranges when the zones are unoccupied especially for more than four hours The system automatically estimates the change in yearly energy costs as you adjust the comfort schedules for different zones Proper settings save energy without affecting the comfort in rooms when they are occupied e Use the Smart Controller saver mode in rooms that are not being used every day e Use the away mode whenever your home is unoccupied for more than four hours If you set your return time your home will be comfortable when you return e Use settings that encourage circulation Circulation saves energy by moving heat from an area with too much heat to an area that can use heat This is especially important if you have a multi story home since warmer air rises to For greater the top floor while cooler air falls to the bottom floor Circulation helps balance temperatures between floors energy savings without using conditioning use settings that As much as possible maintain airflow pressure at the highest setting with which you are comfortable Higher airflow pressure means that f
