5.6.45 Short oper. time in heating mode (C)
Function:
Compressor operation for heating is on
average shorter than 10 min per start based on a
minimum of 5 starts within 24 hours. The alarm resets
automatically at midnight.
Heat pump: All.
B
Check that the heating system is correctly installed.
B
Check that the installation is correctly dimensioned.
B
Check that any flow adjustments are correctly
implemented.
5.6.46 Temporary error G2 heat carrier pump (C)
Function:
The circulation pump has given an error signal
for less than 3 minutes.
Heat pump: All.
Not displayed in the alarm list.
5.6.47 Temporary error G3 coll. circuit pump (C)
Function:
The circulation pump has given an error signal
for less than 3 minutes.
Heat pump: All.
Not displayed in the alarm list.
5.6.48 Control unit restarted (C)
Function:
The control unit restarted due to insufficient
voltage.
Heat pump: All.
B
Check the voltage to the heat pump and 24Vac.
5.6.49 Replace memory battery (C)
Function:
The battery voltage has fallen. If the supply
voltage disappears when the battery is empty there is a
risk that the control unit will lose software, which will
require reloading.
Heat pump: All.
B
Replace the battery (replacement battery CR2032).
5.6.50 Start-up attempt interrupted (C)
Function:
At compressor start the temperatures and
pressure switches are checked. When one of these is not
approved by the control unit the start attempt is
cancelled. A new start attempt occurs after 20 min if a
demand arises.
B alarm is activated when the alarm has occurred more
than once during the last 120 minutes (
