15.8 Settings to be carried out by the
installation electrician
The following settings shall be made by the installation electrician
after installation:
• Select main fuse size.
• Select effect limitation.
• Check room sensor connection.
• Check that the sensors connected indicate reasonable values.
• Carry out the following checks:
Check room sensor connection
1. Scroll down and select the LED Room Sensor option in the "Installer/
Service/Function Test/Heating Circuit" menu.
2. Select “On”. Check that the room sensor LED lights up. If not, check
the cables and connection.
3. Select “Off”. If the LED goes off, the check is complete.
Checking connected sensors
If any sensor is incorrectly connected, a message will appear on the display,
e.g. “Alarm 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. Note the alarm function of the room sensor
(LED) cannot be detected on the display. It must be checked on the room
sensor. The current sensor connection has no alarm, but the current value
can be read in the “Operation data” menu.
15.9 Installing a backup power supply
The DIP switch on the PCB 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.
