12. Operation and Control
12.1 Basic Function
Inverter 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, the microcomputer maintains the set temperature by measuring the temperature of the environment and
performing temperature shifting. The compressor at outdoor unit is operating following the frequency instructed by
the microcomputer at indoor unit that judging the condition according to internal water setting temperature and water
outlet temperature.
12.1.1 Internal Water Setting Temperature
Once 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 shifted value will be used as internal water setting temperature and it is updated continuously
whenever the electrical power is supplied to the unit.
12.1.2 Heating Operation
12.1.2.1 Thermostat control
š
Compressor is OFF when Water Outlet Temperature - Internal Water Setting Temperature > 2°C for continuously
3 minutes.
š
Compressor is ON after waiting for 3 minutes, if the Water Outlet Temperature - Water Inlet Temperature
(temperature at thermostat OFF is triggered) < -3°C.
12.1.3 Cooling Operation
12.1.3.1 Thermostat control
š
Compressor is OFF when Water Outlet Temperature - Internal Water Setting Temperature > -1.5°C for
continuously 3 minutes.
š
Compressor is ON after waiting for 3 minutes, if the Water Outlet Temperature - Water Inlet Temperature
(temperature at thermostat OFF is triggered) < 3°C.
