I created a radiator system for the heating needs of my building. The building is a single thermal zone. In ''Thermal Zone'' section I placed a ''Baseboard Radiant Convective Water'' and created both cooling and heating Thermostat Schedules. I linked the baseboard radiant to plant loop 2. The plant loop 2 consists of an HW boiler, a variable speed pump, a setpoint manager and the radiator which apeared automatically when was linked to the loop. However, after running the simulation the result show that the system it doesn't even exist. No errors appeared on simulation progress.
