[D] Benefit kWh rate power supply
■
If [D-01]=1 or 2 and the benefit kWh rate signal of the electricity
company is received, following devices will be switched off:
■
[D-01] Defines whether or not the unit is connected to a benefit
kWh rate power supply.
If [D-01]=0, the unit is connected to a normal power supply
(default value).
If [D-01]=1 or 2, the unit is connected to a benefit kWh rate
power supply. In this case the wiring requires specific installation
like explained in
"Connection to a benefit kWh rate power
supply" on page 14 .
When parameter [D-01]=1 at the moment that the benefit kWh
rate signal is sent by the electricity company, that contact will
open and the unit will go in forced off mode
(1)
.
When parameter [D-01]=2 at the moment that the benefit kWh
rate signal is sent by the electricity company, that contact will
close and the unit will go in forced off mode
(2)
.
[E] Unit information readout
■
[E-00] Readout of the software version (example: 23)
■
[E-01] Readout of the EEPROM version (example: 23)
■
[E-02] Readout of the unit model identification (example: 11)
■
[E-03] Readout of the liquid refrigerant temperature
■
[E-04] Readout of the inlet water temperature
[D-00] Compressor
0 (default) Forced off
1 Forced off
2 Forced off
3 Forced off
NOTE [D-00] settings 1, 2 and 3 are only meaningful if
the benefit kWh rate power supply is of the type
that power supply is not interrupted,
(1) When the signal is released again, the voltage free contact will close and
the unit will restart operation. It is therefore important to leave the auto
restart function enabled. Refer to
"[3] Auto restart" on page 19 .
(2) When the signal is released again, the voltage free contact will open and
the unit will restart operation. It is therefore important to leave the auto
restart function enabled. Refer to
"[3] Auto restart" on page 19 .
NOTE
[E-03] and [E-04] readouts are not permanently
refreshed. Temperature readouts are updated
after looping through the field setting first codes
again only.
