BA ROTEX HPSU compact 2 - 04/2011
[D] - Off-peak mains connection
This parameter allows for the configuration of the HPSU compact given a Off-peak mains connection.
The following setting options are available:
– [D-00]: Sets which heating elements are switched off when the off-peak signal is received from the energy supply company
(EVU). As a prerequisite, parameter [D-01] must be set to "1" or "2".
Tab. 4-2
Configuration table for parameter [D-00]
– [D-01]: Defines whether the interior heat pump unit (HPSU compact) is connected to an off-peak mains connection.
0 = Normal mains connection (default setting).
1/2 = Off-peak mains connection (see enclosed installation guide).
.
– [D-03]: Adjustment value for the weather-dependent target temperature regulation around the freezing point: In the
temperature range around the freezing point (range "B"), defrosting of the external heat pump unit frequent. To compensate
for these downtimes, we recommend you increase the target feed temperature in this range by setting the adjustment
value "A" (see fig. 4-12).

Settings [D-00] - [D-03] are only relevant if there is no interruption to the power supply for the type of off-peak
mains connection.
[D-01]=1: Is at the moment when the electricity supply company sends the off-peak signal, the contact is opened
and the unit is switched to "Forced OFF". If the signal is sent again, the de-energised contact is closed and the
machine resumes operations. For this reason, it is important to activate the automatic restart function.
[D-01]=2: Is at the moment when the electricity supply company sends the off-peak signal, the contact is closed
and the unit is switched to "Forced OFF". If the signal is sent again, the de-energised contact is opened and the
machine resumes operations. For this reason, it is important to activate the automatic restart function.
