[. . . ] Based on Toshiba's proven light commercial air conditioning system, the Super Digital Inverter, this innovative unit features DC twin rotary compressor, DC inverter and R410A refrigerant, providing the highest coefficient of performance (COP) in its class. This means more power from less energy consumption, and the ideal ecological and economical solution for your home. Hot water cylinder Hydro unit Outdoor unit 8 kW 11 / 14 kW Outdoor unit Hot water cylinder Hydro unit 3 1. INTRODUCTION Engineering Data book Advantages World-leading energy efficiency - COP of 4. 66* With its best in class COP performance, Estía air to water heat pump system delivers more heating power with less energy consumption. Estía uses high quality components and material which contribute to the overall savings in energy consumption. With the Toshiba advanced inverter, Estía air to water heat pump system only delivers the heating capacity required; thus consuming only the necessary electricity.

HYDRO UNIT INSTALLATION MANUAL Engineering Data Book 12TROUBLESHOOTING Fault Symptoms Symptom Possible cause Incorrect remote controller setting Room is not heated or cooled. Incorrect function code setting Backup heater disconnected Insufficient capacity Sensor defect Power is not supplied. Nothing is displayed on the remote controller. Incorrect setting Air bite in the pump Low hydraulic pressure Flow rate switch is activated. Large resistance on the hydro side Malfunction of motorized 3-way valve for hot water supply Excessive hydraulic pressure Hot water leaks from pressure relief valve. Corrective action Check remote controller operation and temperature setting Check function code setting with the function code table. Check backup heater and bimetal thermostat. Check whether temperature sensor is installed at the normal position. Check DIP switch setting on the Hydro Unit board. This alarm is checked immediately after power-on. (This alarm is inhibited while the unit is not working, but occurs again after the unit operates. ) Pump defect or abnormal flow rate This alarm is not reset automatically. Excessive water temperature increase by the heating heater Auto-reset: Excessive water temperature increase in the hot water cylinder Freezing is detected. Auto-reset: High-pressure switch malfunction This alarm is not reset automatically. Low-pressure sensor malfunction This alarm is not reset automatically. Overheat preventive operation malfunction Auto-reset: When operation mode is changed Release preventive operation malfunction This alarm occurs when the Hydro Unit enters the forced-stop zone 10 times.
