1.03
This parameter is used to set a temperature, at which compressor starts to slow down its speed.
Also, the set value is based on
Δ
T.
Compressor always works with its maximum allowable speed, if actual water temperature is lower
than
[
]
(
in
heating mode) or higher than [Tset+1.03]
(
in
cooling mode).
When actual temperature is between [Tset-1.03
,
Tset] ιν
heating
mode
or [Tset, Tset+1.03] in cooling
mode, compressor will
adjust its working speed, to balance the total heating output and system load.
This setting is to keep a balance between comfort and energy saving. If this value is set too big even if
the room is not warm (or cool) enough, compressor will slow down its speed quite soon to save energy.
If this value is set too small, even if the room is warm (or cool) enough, compressor will slow down its
speed
quite late, which consumes more power
.
It’s more like a setting that tells the heat pump unit which temperature range you
'
d prefer to have the
heat pump stayed in.
For
example, in heating mode, if Tset
=
48
℃,
and 1.03
=
2
℃,
compressor will work as hard as possible
to get 46
℃
as soon as possible. Then compressor will lower its speed. If even the compressor works in
its lowest
allowable speed, but actual water temperature still goes over [Tset+1.01], unit stops.
