34 ENERGY SAVING
34.1 ENERGY SAVING: DIGITAL INPUT ACTIVATION
The energy saving is activated when one of the digital input configured as energy saving is ACTIVE.
The energy saving activation is signalled by icon Vset lighted. When working in Chiller or Heat Pump the first pressure on SET key
shows the actual setpoint SetC (chiller) or SetH (HP) labels while the top display shows the set value.
If the energy saving is active the next pressure on the SET key shows the label “SEtr” (real setpoint), and the top display shows the
real set value active in that moment.
During the Energy Saving cycle the setpoint is incremented with these parameter values ES14 / ES16: SET + ES14 for Chiller mode
and SET + ES16 for HP mode.
The differential values, during the energy saving thermoregulation, are defined with parameter ES15 for chiller mode and ES17 and
Heat Pump mode.
34.2 ENERGY SAVING TIME TABLE WITH RTC
The Energy Saving function with a daily RTC time table is available only if the RTC circuit (optional) is on board.
This function allows to set three start and stop energy saving daily periods (ES1..ES2, ES3..ES4, ES5..ES6).
The energy saving activation is signalled by icon Vset. When working in Chiller or Heat Pump the first pressure on SET key shows the
actual setpoint SetC (chiller) or SetH (Heat Pump) labels while the top display shows the set value.
If the energy saving is active the next pressure on the SET key shows the label “SEtr” (real setpoint), and the top display shows the
real set value active in that moment.
During the Energy Saving cycle the setpoint is incremented with these parameter values ES14 / ES16: SET + ES14 for Chiller mode
and SET + ES16 for Heat Pump mode.
The differential values, during the energy saving thermoregulation, are defined with parameter ES15 for chiller mode and ES17 and
Heat Pump mode.
The function can work if the following requirements are satisfied:
1. RTC circuit mounted.
2. Parameters ES01…ES06 are not equal to 0 and are not programmed with the same value.
34.3 RTC DAILY TIME TABLE PROGRAMMING
This function can be also used to turn ON or OFF the unit.
Enter parameter programming:
1. Select with UP or DOWN keys the ES parameter family.
2. Within the ES parameters select with UP or DOWN keys the parameters ES01…ES06 to determine the start and stop of the
energy saving daily periods.
Example
Set the energy saving start with ES01 and the energy saving stop time ES02 of the first period:
If ES01 = 8.0 ES02 = 10.0 the energy saving setpoint is active from 8 to 10.
If ES01 = 23.0 ES02 = 8.0 the energy saving setpoint is active from 23 (11pm) to 8 (8 am) in the morning of the next day.
If necessary repeat the operation for the others two time periods defined by ES03…ES04 and ES05…ES06.
34.4 ENERGY SAVING OR UNIT ON/OFF ACTIVATION WITH RTC PROGRAMMING
Enter the parameter programming:
1. Select with UP or DOWN keys the ES parameter family.
2. Within the ES parameters select with UP or DOWN keys the parameters ES07 (Monday)…ES13 (Sunday) to determine which
days to include.
