Hot-water production

Hot-water tank loading (SLP)

The output controls a hot-water circuit loading pump during the
respective operational-readiness times upon demand.
The hot-water daytime temperature provides for the desired hot
water temperature during hot-water circuit operational-readiness
times in automatic mode and in the PARTY and HEATING control
modes.
This set value is the initial value for the temperature specifications
that can be set for each heating cycle in the switching-time
programs. The temperature settings in the switching time
programs are automatically adjusted when the hot-water daytime
temperature is changed.
Example: Before
Daytime hot-water temperature value: 50°C
Temperatures in switching-time program:
05:00 hours – 08:00 hours
08:00 hours – 16:00 hours
16:00 hours – 22:00 hours
Example: After
Daytime hot-water temperature value: 52 °C
Temperatures in switching-time program:
05:00 hours – 08:00 hours
08:00 hours – 16:00 hours
16:00 hours – 22:00 hours
Changed settings are stored when key
again or after automatic return at a preset time. Once the settings
are stored, the unit automatically switches to the basic display.
