Revision history [back]

Goodmornig. I'm trying to simulate an hydronic system with high temp radiators with Openstudio but I'm having some problems. I'll explain what I've done:

• the building has a single thermal zone and several spaces;
• I create an empty plant loop where I define a "gas boiler", a "HW Htg Coil", "Varibale speed pump" and a temperature manager. I connected the "HW Htg Coil" with the following air loop
• I create an empty air loop where I define a "HW Htg Coil" and I connect the loop with the sigle thermal zone.
• In the "zone equipment" I insert a high temp radiant

When I launch the simulation the system returns me a Fatal error "AirLoopHVAC="..." is not connected to any zone". In the sheet Thermal Zones the Air Loop Name report the name of the air loop I inserted.

I'm definitely forgetting a step but I can't find where.

Thanks to anyone who can help me
