Solar module
SM2-2
- Extension module to control one solar thermal system with up to 2 cylinders and 2 collector arrays, incl. 1 collector sensor and 1 cylinder sensor, each with a sensor well
- Easy controller configuration by selecting one of the preset system versions
- Used in conjunction with WOLF heat generators, more energy can be saved by intelligent cylinder reheating, i.e. cylinder reheating is blocked when sufficient solar energy is available
- Heat metering with external heat meter for all configurations
- Selection of cylinder operating mode
- Display of the set and actual values on the BM-2 programming unit
- eBus interface with automatic energy management
- Rast 5 connection technology
- Including 1 collector temperature sensor, 1 cylinder temperature sensor, each with sensor well
