FUNCTION trEM to show the temperature of the remote panels

Identification label trEM.

trE1 value of the NTC probe of the remote #1

trE2 value of the NTC probe of the remote #2

Select with UP or DOWN the trEM function

Push SET the trE1 or trE2 label is shown on the bottom display, the top display shows the probe value.

Use the UP or DOWN arrow to change beteween trE1 or trE2 read-out.

To exit to the normal display read-out push MENU or wait the time – out time.

ATTENTION:

THE trEm function and the labels trE1 or trE2 appear only if the CF74 = =2 or 3 (remote panel 1 configuration) or if the parameter CF75

= 2 or 3 (remote panel 2 configuration).

18 ENERGY SAVING

18.1 ENERGY SAVING FROM DIGITAL INPUT

The energy saving is activated when one of the digital input configured as energy saving is ACTIVE.

The energy saving activation is signalled by the SET key led on. When working in Chiller or HP 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 HP

mode.

18.2 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 the SET key led on. When working in Chiller or HP 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 HP

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.

18.3 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.

18.4 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.
