- 7-1Error code1. Purpose The operations of the hydro unit and the outdoor unit are controlled according to user-defined operation condition settings. 2. Details The operation controls include those shown on the left. 3. Operations 1) An operation condition is selected with the remote controller. 2) Setting the remote controller button to “ON” transmits a signal to the hydro unit. 3) The hydro unit controller controls the operations shown on the left while also controlling the water 2-way valve, water 3-way valve, circulation pump, mixing valve, hot water cylinder heater, and backup heater. 4) The hydro unit controller transmits an operation instruction to the outdoor unit, and uses serial signals to transmit and receive control statuses. 5) The outdoor unit control unit performs the operation controls shown on the left while also controlling the compressor, outdoor fan motor, pulse motor valve, 4-way valve, 2- way valve, and bottom plate heater

Operation Mode and Control Method 1) Heat pump operation range of hot water supply, heating and cooling 2) Hot water supply operation 3) Heating operation 4) Cooling operation 5) Simultaneous operations of ʺhot water supplyʺ and ʺheatingʺ 6) Simultaneous operations of ʺhot water supplyʺ and ʺcoolingʺ 7) Boiler control 8) Hot water boost operation 9) Anti bacteria operation 10) Night setback operation 11) Frost protection operation 12) Auto operation 13) Night time low-noise operation
- 7-3Error code7-3. Hydro Unit Control 1) Capacity control (compressor, high-temperature release, low-temperature release) 2) Heater control 3) Circulation pump control 4) Control by the flow sensor 5) Mixing Valve control (2-temperature heating control) 6) Room temperature control 7) Room temperature control with the thermostat 8) Hot water cylinder thermostat control 9) Control of Mode selection and forced stop & restart 10) Control of limit of heat pump operation (Tempo1, 2) 11) Connection to a Smart Grid network (SG ready) 12) Output signal control 13) Q-H characteristics of hydro unit 14) Automatic restart control 15) Piping freeze prevention control 16) High return water protect control
- 7-4Error code7-4. Outdoor unit control 1) PMV (Pulse motor valve) control 2) Discharge temperature release control 3) Current release control 4) Outdoor fan control 5) Defrosting control 6) Winding heating control 7) Short circuit operation prevention control 8) Over current protection control 9) High pressure release control 10) High pressure switch 11) Compressor case thermostat 12) Bottom plate heater control 13) Start up from hibernation 14) Liquid injection control
