EXTERNAL AIR TEMPERATURE AND WATER TEMPERATURE
The heat pump is inhibited (compressor startup inhibition) when the water temperature reaches the maximum value set through parameter
0636
near the air temperature set using parameter
133E
. This value will change dynamically (according to the band set with parameter
133H
),
decreasing in proportion to the decrease of the external air temperature (differential set with parameter
133F
), in accordance with the function
described below.
In order to allow a limitation of the air temperature produced even at high temperatures, similarly to what just described, it will also be possible to
set parameters “
133R
, “
133S
” and “
133T
” in accordance with the function described below:
The probe is configured using parameter
P132Z
.
If the compressor is on in adjustment mode, the unit will continue to operate normally, in accordance with the active protections (envelope control,
temperature limits, pressure control).
