Delay StartBackup CH
(HP030)
Delay time for starting the
backup energy source for the
heating circuits
Can be set from 1 to 600 mi
nutes.
If the Delay StartBackup CH
(HP030) parameter is set to 0,
the time delay for activating
the back-up is set depending
on the outdoor temperature.
20 minutes
Delay stop backup CH
(HP031)
Delay time for stopping the
backup energy source for the
heating circuits
4 minutes (default value)
If the Delay StartBackup CH parameter is set to 0, the time delay for
activating the back-up is set depending on the outdoor temperature: the
lower the outdoor temperature, the quicker the back-up will be activated.

Important
In this example, with the factory-set parameters, if the outdoor
temperature is 10 °C, the back-up will start up 25 minutes after the
outdoor unit of the heat pump.
