by means of B4/B5 or SW4/SW5 (if a Tset higher than 27°C was previously selected in
cooling, when the heating mode is selected the Tset must be automatically set to 21°C),
and its value is shown both on remote and local interfaces (by D1, D2, and S1+S2=’°C’).
Once heating mode is selected, if Troom
≥
Tset nothing happens (all outputs remain switched off).
If Troom
≤
Tset-Hy and Res_time seconds from previous compressor shutdown are elapsed, the 4-way
valve is activated first, then compressor and external fan can be switched ON.
As soon as Troom
≥
Tset the compressor and external fan are switched OFF (the 4 way valve must remain
energized).
Next time the condition Troom
≤
Tset-Hy occurs, provided that Res_time seconds from previous
compressor shutdown are elapsed, compressor and external fan can be switched ON again.
Internal fan it’s switched to low speed for t_lowspeed seconds from each compressor start time (regardless
of any speed selection), then it can be switched to actual selected speed. Each time the compressor is
switched OFF (due to Troom
≥
Tset or unit to Stby mode), the internal fan is set to low speed for
t_lowspeed seconds and then it’s switched OFF.
Here are the details about the available fan speeds:

When auto fan speed is selected (only from the remote control by pressing B7), the actual speed is selected
depending on room temperature and Tset as following (only when the compressor is ON, otherwise the int
fan keeps OFF):
•
Tset – 3°C < Troom
≤
Tset: minimum speed is enabled;
•
Tset – 6° < Troom
≤
Tset-3°C: medium speed is enabled;
•
Troom
≤
Tset-6°C: maximum speed is enabled.
At least 3 minutes must elapse between one automatic speed change and another (if Tset or fan speed
selection is changed, the new speed is enabled without any delay).
The display L1 shows the auto fan mode by cyclically switching the fan speed symbols as follows:

The heating defrost subprogram starts when Troom
≤
Tdefrost and ends when Troom > Tdefrost +2°C,
and forces the compressor to periodically switch OFF and switch ON for t_defrost_off minutes (OFF state
duration) and t_defrost_on minutes (ON state duration) respectively.
When the heating defrost function is active, the internal fan behaves as usual in heating (each time the
compressor is switched ON, it’s set to low speed for t_lowspeed seconds first then to the selected fan speed;
each time the compressor is switched OFF, it’s set to low speed for t_lowspeed seconds first, then it’s
switched OFF).
