System-specific functions
The following adjustments are used for the specific functions in system 3. The chan-
nels described are not available in any other systems.
Thermostat function
Backup heating
Use of surplus
energy
The thermostat function works independently from the solar operation and can be
used for using surplus energy or for backup heating.
• AH O < AH F
thermostat function for backup heating
• AH O > AH F
thermostat function for using surplus energy
The symbol
⓶
will be shown on the display, if the second relay output is activated.
S3 is used as the reference sensor for the thermostat function.
AH O
Thermostat switch-on temperature
Adjustment range: 0.0 … 95.0 °C [30.0 … 200.0 °F]
Factory setting: 40.0 °C [110.0°F]
AH F
Thermostat switch-off temperature
Adjustment range: 0.0 … 95.0 °C [30.0 … 200.0 °F]
Factory setting: 45.0 °C [120.0 °F]
t1 O, t2 O, t3 O
Thermostat switch-on time
Adjustment range: 00:00 … 23:45
Factory setting: 00:00
t1 F, t2 F, t3 F
Thermostat switch-off time
Adjustment range: 00:00 … 23:45
Factory setting: 00:00
In order to block the thermostat function for a certain period, there are 3 time
frames t1 … t3.
If the thermostat function is supposed to run from 06:00 a.m. to 09:00 a.m. only,
adjust t1 O to 06:00 a.m. and t1 F to 09:00 a.m.
If the switch-on and switch-off times of a time frame are set to an identical value,
the time frame will be inactive. If all time frames are set to 00:00, the thermostat
function is solely temperature dependent (factory setting).
