8.2 Checking connected sensors
If any sensor is incorrectly connected, a message will appear on the display,
e.g. “Alarm: [E030] sensor out”. If several sensors are incorrectly connected,
the different alarms are displayed on different rows.
If no alarm is displayed, the sensors are connected correctly.
8.3 Pressure/level switch
The pressure/level switch is connected to blocks G73 and G74 and then
defined under the Installer/Define system/Def Heat pump menu.
8.4 Installing a backup power supply
The DIP switch on the relay card (A2) is used to set the backup power
supply. The DIP switch is marked “RESERV” (BACKUP).
When the switch is set to ON, the step is actively operating in backup
heating mode.
Factory-set value 2.1 KW distributed across 3x400 V. Adjust the value
according to the needs and capacity of the building.
