cooling tower and condenser pump are not functioning properly

I’m running an EnergyPlus simulation, but my cooling tower and condenser pump are not functioning properly. I’m sure there are no errors in the connections of branch, branchlist, and node. I’ve also set up the related schedules, including CondenserLoop, CondenserEquipmentOperationSchemes, CondenserEquipmentList, and PlantEquipmentOperation:CoolingLoad.

Could anyone help me check if I’ve missed any settings that might be causing the cooling tower and condenser pump to malfunction? I’ve attached my relevant settings below. Thank you very much!!

Could anyone help me check if I’ve missed any settings However, the results of the simulation shows that might be causing the energy consumption of cooling tower and condenser pump are both zero. This might mean that the two equipment is not functioning, and hence leads to malfunction? I’ve attached my relevant settings below. zero energy consumption. Could you please suggest what might lead to this situation? The energy consumption of the two equipment should not be zero. Thank you very much!!you.
