Three modes are possible:
– ECO (factory setting) : The heating function is
switched off and the controller monitors the outside
temperature.
If the outside temperature falls below 3 °C, the con-
troller switches the heating function on after the end
of the frost protection delay time and brings the room
temperature to the set desired "Night" temperature.
Even though the heating function is on, the burner is
only active as required.
If the outside temperature rises above 4 °C, the con-
troller switches the heating function off, but contin-
ues to monitor the outside temperature.
– Frost protection: The heating function is off and the
frost protection function is active.
– Set-back temperature: The heating function is on
and the controller brings the room temperature to the
set desired "Night" temperature.
When installing your controller, the heating engineer can
specify the control functions for the times outside the
periods and the heating curve.

Discuss with the heating engineer which settings are
optimum for you.

5.2.2 Modes for hot water production and
circulation
i
The mode for hot water production and circu-
lation depends on the set mode for heating
circuits "HEATING 1" and, if relevant, "HEAT-
ING 2". No other mode can be set.
i
If you have assigned different functions,
modes or advanced functions to two inde-
pendent heating circuits, then the controller
assigns the mode with the greater heat
requirement to hot water production and cir-
culation (
¬
Tab. 5.1 ).
If the heating system is equipped with one heating cir-
cuit, the controller regulates the hot water production
and, if relevant, the circulation in accordance with the
mode for this heating circuit.
If the heating system is equipped with two heating cir-
cuits, the heating engineer can define which heating cir-
cuit controls the hot water production and, if relevant,
the circulation.
Automatic mode and Summer mode
Automatic mode and Summer mode control the hot
water production in accordance with the set desired
temperature for "hot water" and the set periods. In the
"Time programmes" function, you have set periods for
hot water production. If you have not set any periods,
the controller uses the period set in the factory settings
for hot water production (
¬
Tab. 4.2 ).
Within the period, hot water production is switched on
and keeps the hot water in the domestic hot water cylin-
der at the set temperature. Outside the period, hot
water production is deactivated.
Automatic mode and Summer mode control the circula-
tion of hot water in the hot water pipes in accordance
with the set periods.
Within the periods, circulation is activated and outside
the periods it is deactivated.
Comfort mode
Comfort mode controls hot water production in accord-
ance with the set desired temperature for hot water
without taking periods into account.
Circulation is activated and the periods for circulation
are not observed.
