Heating only. When the DP120 differential is reached, domestic hot water production is triggered.
If there is not enough domestic hot water (e.g. if the domestic hot water does not heat up quickly
enough): reduce the trip differential (hysteresis) by modifying the value of the DP120 parameter. The
DHW tank will then heat up the water more quickly.

Running the back-up in domestic hot water mode
Start-up conditions for the back-up
The start-up conditions for the back-up producing domestic hot water are
described in the following table.

AP001
The function of the BL1 blocking input is not set to 4, 6 or 8
AP100
The function of the BL2 blocking input is not set to 4, 6 or 8
Operating description
The behaviour of the hydraulic or electrical back-up in domestic hot water
mode depends on the configuration of the DP051 parameter.

Operating description
0
The system gives priority to the heat pump during domestic hot water production.
Recourse to the hydraulic or electrical back-up is only taken if the DP090 time delay has elapsed in
domestic hot water mode, unless hybrid mode is activated. In that case, hybrid logic takes over.
1
Domestic hot water production mode gives priority to comfort by accelerating domestic hot water pro
duction by simultaneously using the heat pump and the hydraulic or electrical back-up.
In this mode, there is no maximum time for domestic hot water production as the use of the back-ups
helps to ensure domestic hot water comfort more quickly.
