YES, DualSun SPRING panels are compatible with the SOLERIO OPTIMUM 2 tank from ATLANTIC, subject to the following checks:
- Solar controller: The controller tank is pre-parametrized with the following values (non-modifiable parameters):
- Delta_T ON : +7°C
- Delta_T OFF : +3°C
- Minimum triggering temperature: +30°C
These values, although slightly different from the DualSun recommendations, are acceptable and allow the system to function properly.
- Solar station: The solar station of this tank has no contraindication for DualSun compatability.
Expansion tank: The standard expansion tank for this model has a volume of 18L for a 300L tank.
The DualSun recommendation in most cases is to install an expansion tank of 15L. The expansion tank of the Solerio tank is compliant.
