If 1 hour before "Normal Shower Time" set in "Time and Timer Setting" under Basic Operation , hot water temperature
has still not reached the set value, unit will activate standard hot water operation to ensure you can enjoy enough hot
shower water at/after this time.
These parameters are valid only for the units with heat recovery function. For the unit without this function, "Heat
Recovery Function" should always set to 1 (invalid).
If it is set to ON, unit will try to heat up the hot water by recover the wasted heat in heating and cooling operation.
It will turn ON heat recovery circuit if actual hot water temperature is "Hot Water Restart Based On ∆T in Heat Recovery
Operation" lower than set hot water temperature, and stop after it heat the hot water to "Hot Water Stop Based On ∆T in
Heat Recovery Operation" over set hot water temperature.

If "Shifting Priority" function is turned ON in "Temperature Parameter" setting under Basic Operation, when actual
ambient temperature is lower than
"
Shifting Priority" setting, Shifting Priority function will be activated.
Unit will firstly work in Hot Water Mode. If it gets the set temperature for hot water, or it has been working in Hot Water
Mode over "Hot Water Min. Working Hours in Shifting Priority Operation", and temperature for heating has dropped
over "Allowable Temp Drift In Heating in Shifting Priority Operation" based on set heating temperature, unit switch to
heating. After switch to heating operation, if it gets the set temperature for hot water, or it has been working in heating
operation for over " Heating Max

In shifting priority operation, when the unit switches to heating , this function can be activated to turn on extra heating
source for hot water, and help to reach the set temperature for hot water.
If Parameter E7 is set as 1, the extra heating source for hot water will turn on when unit switches to heating in shifting
priority operation.
If Parameter E7 is set as 0, the extra heating source for hot water will turn off when unit switches to heating in shifting
priority operation.
Note: The extra heating source for hot water should be connected to the port HTW on the indoor PCB toactivate
the function. For AWT model, this function is invalid, because 1.5KW electric heater inside the water tank is
controlled bydigital thermostat directly, and there is no other heating source connected to HTW port.
