9.3 Description of the parameters
9.3.1 Running the back-up in heating mode
Start-up conditions for the back-up
Important
If the AP001 and AP100 parameters are configured to 4, 6 or 8
and the corresponding BL input is active, the back-ups will be
deactivated and will only start up for safety reasons and to
enable defrosting.
If the HP030 and HP031 parameters are set to 0, the activation
and deactivation time delays on the back-up are set according
to the outside temperature.
In heating mode, the back-up is managed by the following parameters:
Tab.62 Parameter for heating production
Parameter Description
AP016 Activate or deactivate processing of the heating demand for central heating
HP030 Start-up time delay for the next back-up generator in central heating mode (t1).
HP031 Shutdown time delay for the next generator in central heating mode (t2).
AP001 Selection of the BL blocking function when a signal is applied at the input (BL1).
AP100 BL2 input function configuration.
The time delay curve for tripping the back-up is defined by the HP047,
HP048, HP049 and HP050 parameters.
1 HP047: Minimum duration of the time delay for tripping the back-up
2 HP048: Maximum duration of the time delay for tripping the back-
up
3 HP049: Minimum outside temperature for the time delay for
tripping the back-up
4 HP050: Maximum outside temperature for the time delay for
tripping the back-up
T Time (minutes)
t Outdoor temperature (°C)
Back-up operation if an error occurs on the outdoor unit
If an error occurs on the outdoor unit during a system heating demand, the
electrical back-up starts up immediately to guarantee heating comfort.
Back-up operation if defrosting the outdoor unit
When the outdoor unit is undergoing defrosting, the control unit ensures
full protection of the system by starting up the back-ups if necessary.
Additional protection is provided if the water temperature falls too sharply.
In this case, the outdoor unit is shut down.
Operating principle when the outside temperature falls below
the operating threshold of the outdoor unit
If the outside temperature is below the minimum operating temperature of
the outdoor unit as defined by the parameter HP051, the outdoor unit is
not permitted to operate.
