Table 5 shows the settings to be configured to enable the integrations in "summer and sanitary" mode (in this case the only activation that can
be activated is the DHW integration heater and the division into operating brackets does not apply).

10.10.1 AUXILIARY SYSTEMS OFFSET MANAGEMENT
Lastly you may establish that the boiler and/or integration heaters (according to the resources and selected priorities) have a setpoint in heating
mode and in sanitary mode higher than that of the heat pump. This is achieved by setting an offset on the following setpoints:
• r29 = First setpoint temperature offset for boiler and plant heaters (G02);
• r30 = Second setpoint temperature offset for boiler and plant heater (G05);
• r31 = Temperature offset for boiler and DHW heaters (G03);
This way the heat pump stops at the setpoint (G02,G03,G05) and the temperature difference, according to the set outset, will be supplied by
the boiler and/or heaters.

TABLE 6. INTEGRATION HEATERS OPERATION
PLANT INTEGRATION HEATER
Works as indicated in TABLE 1,2,3 and 4.
Only if all 3 of the following conditions are met:
-the output is configured for Plant integration
heater;
-r24=1/3;
-plant water temperature remote probe pres-
ent and configured;
the plant integration heater is activated in the
following situations:
- r12 minutes after the start of its count acti-
vated in "HEAT" mode previously running (see
line 1);
- if its count is not already activated in the pre-
vious "HEAT" mode, r12 minutes after the tem-
perature control demand.
- In SANITARY mode, with remote probe not
configured, the plant integration heater is de-
activated or any of its counts are interrupted.
- With "remote on-off" contact open, the Plant
integration heater is deactivated.

DHW INTEGRATION HEATER
In "HEAT+SAN", by default sanitary temperature con-
trol has priority over that of the plant, therefore if re-
quired by the temperature control, the unit goes to
"SANITARY" mode and the DHW integration heater acts
as indicated in TABLES 1,2,3 and 4.
Works as indicated in TABLES 1,2,3 and 4.
