(1) In standby state, press reset key ⑤and hot water
key② for three seconds, to start dry test run of floor.
The temperature of test run depends on running
time. Setting temperature is shown during running
and the residual running time will be shown too.
(2) Effluent temperature is set as 25ºC for running 72
hours, 35ºC for 48 hours and 40ºC for running 48
hours respectively.
(3) After test run of supplying hot water for seven days,
effluent temperature comes back to setting value. If
the temperature is not set, it will be default value
(35ºC).
(4) When floor is in dry run, the unit can be started and
closed, but the functions and effluent temperature
can not be changed.
(5) The time of floor dry run is cumulative. After the unit
is closed, it will enter floor dry run when it starts next
time.
