Energy saving or unit ON/OFF
with RTC and
X Y
where: X with range 0..7 represents the energy saving
where: Y with range 0..7 represents the unit on/off
Example of a daily programming:
Monday
Enater parameter programming
1.
In the ES parameter family, select the parameter ES07, the top display shows 0 - 0
2. Push SET key: the top display shows 0 - 0 blinking, with UP or DOWN keys select the corresponding function (see next table) :
3. Push SET to confirm.
4. Push SET + UP to exit the programming or wait the programming timeout.
MONDAY
X = 0 - Y= 0: The energy saving and the unit on/off are both disabled:
MONDAY X = 0 - Y= 1 energy saving is disabled, and unit on/off will follow the first RTC period ES1..ES2.
MONDAY X = 3 - Y= 7: energy saving enabled during the 1
st
and 2
nd
RTC periods, unit on/off enabled during the 1
st
, 2
nd
3
rd
periods.
WEEKLY PROGRAMMING
Repeat the daily programming for the other days of the week using parameters ES08..ES13.
19 DYNAMIC SETPOINT
The dynamic setpoint allows to increase or decrease the setpoint with a proportional value determined by Sd01 (chiller) and Sd02 (HP)
that depends from the 4..20mA analogue input or from the external air temperature probe. This function allows to save energy or run the
unit when the external ambient is not within the normal operative conditions.
The dynamic setpoint 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.
The regulation is enabled if:
