Bill,

Thank you for quick response. Does this include the "linear ramp"?

Weixiu

Weixiu,
 
You need to set the loop control to “OA Reset”:
 
Then modify the day schedule:

Can anyone share some experience on how to reset hot water supply temperature as required in G3.1.3.4 of ASHRAE 90.1 - 2004 in eQuest? 
 
"Hot water supply temperature shall be reset based on outdoor dry bulb temperature using the following schedule: 180F at 20F and below, 150F at 50F and above and ramped linearly between 180F and 150F at temperature between 20F and 50F."
 
Thank you,
 
Weixiu Kong
