6213 Operation and Control13.1. Basic FunctionInverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes,automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, themicrocomputer maintains the set temperature by measuring the temperature of the environment and performing temperatureshifting. The compressor at outdoor unit is operating following the frequency instructed by the microcomputer at indoor unit thatjudging the condition according to internal water setting temperature and water outlet temperature.13.1.1. Internal Water Setting TemperatureOnce the operation starts, control panel setting temperature will be taken as base value for temperature shifting processes.These shifting processes are depending on the Air-to-Water Heatpump settings and the operation environment. The final shiftedvalue will be used as internal water setting temperature and it is updated continuously whenever the electrical power is suppliedto the unit.13.1.2. Heating Operation13.1.2.1. Thermostat control• Compressor is OFF when Water Outlet Temperature - Internal Water Setting Temperature > 2°C for continuously 3 minutes.• Compressor is ON after waiting for 3 minutes, if the Water Outlet Temperature - Water Inlet Temperature (temperature atthermostat OFF is triggered) < -3°C.13.1.3. Cooling Operation13.1.3.1. Thermostat control• Compressor is OFF when Water Outlet Temperature - Internal Water Setting Temperature < -1.5°C for continuously 3 minutes.• Compressor is ON after waiting for 3 minutes, if the Water Outlet Temperature - Water Inlet Temperature (temperature atthermostat OFF is triggered) > 3°C.
