10.4 Description of the parameters
10.4.1 Running the back-up in heating mode
Back-up start-up conditions
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 not start up.
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.52 Parameter for heating production
Parameter
Description
AP016
Enable central heating heat demand processing
HP030
Delay time for starting the next generator (backup stage) in central heating mode(t1).
HP031
Delay time for stopping the next generator (backup stage) in central heating mode(t2).
AP001
Blocking input setting (1: Full blocking, 2: Partial blocking, 3: User reset locking)(BL1).
AP100
Blocking input 2 setting.
The time delay curve for tripping the back-up is defined by the parameters
HP047, HP048, HP049 and HP050.
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 trip
ping the back-up
4 HP050: Maximum outside temperature for the time delay for trip
ping the back-up
T Time (minutes)
t Outside 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
boiler or electrical back-up starts up immediately to guarantee heating
comfort.
