Adjustment probe value DECREASING
(Graph nr.2):
With adjustment probe values equal or higher
than point (D), you will have a (iHv) analogue
output.
Between points (D) and (E), the analogue
output will have a value proportional to the
value of the adjustment probe starting from the
maximum value of (iHv) up to the minimum
value of the (iLv) parameter.
With values of the adjustment probe lower
than point (E) and higher than point (F), you
will have an analogue output equal to the
minimum value of the (iLv) parameter.
The analogue output of the adjuster will be 0V
for adjustment probe less or equal to point (F)
representing the "SET point" value.
Digital output nr.1 represents "the condenser
fans inverter activation" and is ON for
adjustment probe value higher than or equal to
the set point and OFF for lower values.
ENERGY SAVING MODE (mOd = 1)
In this mode the control modifies the Set-point according to the external temperature. When the external
temperature drops, so does the set-point. This ensures that a fixed differential is maintained between the
condensing temperature and the external temperature, therefore if the external temperature drops, so does
the reference for the condensing temperature and as a result the compressor efficiency improves.
In this mode the set-point is therefore set automatically and the parameters (LSE) and (HSE) set become the
adjustment limits. In this configuration the type of gas used must be set, in order to adjust the fans properly.
In the “Energy saving” mode it is recommended to use a temperature probe
as an adjustment probe, in
order to facilitate the correct configuration of the parameters and anticipate the external temperature
variations more effectively.
