4.2.2 About Running
System Structure Figure
1)
Unit has two kinds of heat sources: heat pump(compressor)
and electric heater.
Unit will automatically select heat sources to heat water to the
target temperature.
Water outlet
Temperature sensor(T5U)
Water inlet
Temperature sensor(T5L)
Electric heater

Water Temperature Display
The temperature shown on the display depends on the upper
sensor. So it is normal that the display temperature has reached
to target temperature but compressor still running, because the
lower water temperature does not get to target temperature.
