4 If such notes are not observed, personal injury and / or considerable damage to property can Controller may only be used for the control and supervision of heating, ventilation, air conditioning and chiller for flawless and safe operation of Controller are proper transport, installation, commissioning, and correct , switches, wiring and earthing must be in compliance with local safety regulations for electrical for use of commission of Controller must be undertaken by qualified staff who have been appropriately trained by Siemens Building Controller may only be operated by staffs who have been instructed by Siemens Building Technologies or their delegates and whose attention has been drawn to potential wiring the system, the AC 240V section must be strictly segregated from the AC 24V safety extra low-voltage (SELV) section in order to ensure protection against electric shock hazard!

5 !For storage and transport, the limit values given in the relevant Datasheet must be always be observed. System sections accommodated in the control panel should be freed from dust and dirt whenever normal service visits are system faults occur and you are not authorized to make diagnostics and to rectify faults, call your service staff of Siemens Building authorized staffs are permitted to make diagnostics, to rectify faults and to restart the plant. This also applies to work carried out within the control panel ( safety checks or changing fuses).The products contain electrical and electronic components and may not be disposed of as household and currently legislation must be complied with!2/28 Siemens Building TechnologiesSIEMENS ControllerHEAT PUMP controllerHVAC of UseElectrical InstallationCommissioningOperationWiring Storage and TransportMaintenanceFaultsDisposal2 Operation LCD Display Operation of is fully driven by buttons and buttonsSystem +24V+5VQ64Q54Q44Q34Q24Q14Q13D1MD2D3MD4D5 MGG0RS485 GND+-RJ45 LED 1 Display 2(Value)Display 1(Parameter)
