4. Usage
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]in
heating
mode
or [Tset, Tset+1.03]
in
cooling
mode
,
compressor
will
adjust
its working speed, to balance the
total heating output
and system
heating 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

Heating Curve Function
Set whether heating curve function is needed or not.
If
heating curve function is not needed, set 1.05
=
OFF
,
and then you can set a fixed water set
temperature
under heating mode via parameter 1.19
