4-2) Hot water supply and heating fan control
1) The TE sensor, TO sensor and operation frequency control the outdoor fan.
(The minimum W1 to the maximum are controlled according to the table below.)
2) For 3 minutes after the start, the maximum fan tap for each zone that is shown in the following table is fixed. After
that, the fan is controlled according to the TE sensor temperature.
3)
If TE ≥ 24 (30)* °C continues for 5 minutes, the operation stops. No error code is displayed for this; the status is the same
as the usual thermostat off. The operation restarts after 150 seconds. This intermittent running is not abnormal.
* ( ): 801, 1101
If the heat-pump was thermo-off, the out-door fan motor (up/down) continue to run 10 min with W3 rotation.
When the water pump of hydro unit turns on, the fan motor will operate sensing value of outside air temperature (TO).
