Caution
The menu items 10.4 to 10.9 only appear when hydraulic variant 3
is selected (see 12.1)
10.4 TrefS3
menu 5.4
= set temperature at sensor 3
If the thermostat function is active (see 10.8) and the temperature falls
below the set temperature, the additional heating at relais 2 is switched on
until the temperature reaches the set value + hysteresis (see 10.5 hysteresis)
Setting range: from 0°C to 99°C/default setting: 50°C
10.5 Hysteresis
menu 5.5
=
hysteresis of the thermostat function via S3
By setting the hysteresis value the heating of the storage tank can be
adjusted.If the temperature of the Tsetpoint at sensor 3 is exceeded by the
set hysteresis, additional heating at relais 2 is deactivated. If the Energy
saving mode is active (10.6) the system heats up until hysteresis
temperature is reached.
Setting range: from 2°C to 20°C/default setting: 10°C
10.6 Energy saving mode
menu 5.6
If active the the additional heating via relais R2 heats up only till
hysteresis is reached (see 10.7). If Energy saving mode is active,
but no solar charging takes place, Tsetpoint3 is used instead.
Setting range: on, off/default setting: off
Caution
The menu item TminS3 10.7 only appears when energy saving mode
is active (see 10.6)
10.7 TminS3
menu 5.7
=
minimum temperature S3 in Energy saving mode
If the temperature at sensor 3 falls below this value and the thermostat
function is active (see 10.8), additional heating via relais R2 is switched on
until hysteresis is reached (see 10.5).
Setting range: 0°C to 99°C /default setting: 20 °C
