Yes, according to the installation and maintenance instructions for De Dietrich solar tanks. The BSC, BSP, BESC solar heaters model are compatible with DualSun SPRING hybrid solar panels.
Model designation :
BSC/BSP...E = Dual exchanger cylinder
Preparator BESC...E = Electrosolar preparator
The solar control of the storage tank is pre-configured with the following values (parameters cannot be changed):
- Delta_T ON : +7°c
- Delta_T OFF: +3°C
- Minimum trip temperature: + 30°C
These values, although slightly different from the DualSun recommendation, are acceptable and allow the system to function properly.
The solar station of this storage tank does not present any contraindication for DualSun compatibility.
On the other hand, it is not possible to connect a DualSun T-Box because the control system does not have Vbus wiring ports.
The expansion vessels of these tank references have a volume that varies according to the model and tank volume :
These volumes are close to the DualSun recommendations and no modification is necessary.
