20. ENERGY SAVING
It is daily or weekly configurable function with “hour time
table” (if RTC on board) or depending from external digital
input. During the Energy Saving cycle the real setpoint is
calculated with the parameters ES10 and ES12:
SET+ES10 for chiller, SET+ES12 for Heat Pump.
The differential for the function cut-in/out is depending by
ES11 for Chiller and ES13 for Heat Pump.
20.1 Daily Programming
The daily programming is based on 7 parameters ES03-
>ES09 corresponding to the 7 days of the week; the value
1 enable the function for that day.
Eg: ES03 = 1 means that the Energy Saving is activated for
the whole 24 hours on Monday. If needed, repeat the
operation for the whole week ES04(Tue)..ES09(Sun).
20.2 Hour Time Table (with RTC)
Based on two parameters: ES01 Energy Saving start hour
and ES02 Energy Saving stop hour.
Eg: ES01 = 8.0 and ES02 = 10.0 it means that the Energy
Saving is active from 8 to 10.0
for all the days of the week.
Eg: ES01 = 23.0 and ES02 = 8.0 it means that the Energy
Saving is active from 23.0 to 8.0
of the next morning; for all
the days of the week. This function is disabled if the
parameters ES01 / ES02 are both 0.
20.3 Energy Saving with External Contact
The function is enabled when the digital input, configured
as Energy Saving, is activated by remote contact.
21. COMPRESSOR FUNCTIONING
21.1 Compressor Control in Chiller Mode
Parameter CF21=0,3 (1 Compressor selected)
Parameter CF21=1 (1 compressor with step)
Parameter CF21=2 ( 2 compressor )
21.2 Compressor Regulation for Heat Pump
Parameter CF21=0,3 (1 compressor)
