are made in menu “4. Settings”.
Caution
This does not under any circumstances replace
the safety facilities to be provided by the
customer!
The menu is closed by pressing “esc” or selecting “Exit
settings”.
Settings
4.1. - Tmin S (X)
Enable/start temperature at sensor X:
If this value is exceeded at the applicable sensor X and the other conditions are also met, then the
controller switches on the associated pump and/or valve. If the temperature at the sensor drops below this
value by 5°C, then the pump and/or the valve are switched off again.
4.2. - Tmin S5
4.4. -
∆ T Solar S (X)
If the set temperature difference is too small, this may result in ineffective operation,
depending on the system and sensor positions.Special switching conditions apply for speed
control (see „6.3. - Speed control R1 / R2“)!
Caution
Switch-on/switch-off temperature difference for sensor X :
If this temperature difference between the reference sensors is exceeded and the other conditions are also
met, then the controller switches the applicable relay on. When the temperature drops to ΔT Off, then the
relay is switched off.
Priority of Storages X
This determines the order, in which the storages are charged. If the same priority is set for 2 storages, the
charging is not switched over until charging the active storage is not possible anymore.
S. „4.1. - Tmin S (X)“
4.3. - Priority S (X)
4.5. - Tmax S (X)
4.6. - Priority S3
See „4.3. - Priority S (X)“
Switch-off temperature at sensor X
If this value is exceeded at the applicable sensor X, the controller switches the associated pump and/or
valve off. If the temperature falls below this value again and the other conditions are also met, then the
controller switches the pump and/or valve on again.
Temperature values that are set too high can lead to scalding or damage to the system.
Scalding protection must be provided by the customer!
