I am designing a multi-zone AirLoop system that provides cooling and heating during the year. In zone:sizing,coil:heating:water, and coil:cooling:water objects I defined design supply temperature. When it came to simulation inputs I got confused.

I don't know how to specify the supply air temperature for cooling and heating season. Is it possible to define two setpointmanager:scheduled in a same node for cooling/heating modes? thank you in advance for your help.

I use OS:SetpointManager:OutdoorAirReset to change the set point from winter to summer.

You may want to put only one setpointmanager:scehduled on the supply side outled air node, therefore to modify the scheduled value in it (seasonally variyng)!

@Ag That's a good solution. The problem is that there is no specific schedule for heating or cooling. Somedays both are required! Since it's a common situation, I thought there would be something like dual setpoints for thermal zones.
