Solar module
SM1-2
- Extension module to control a solar circuit incl. collector temperature sensor, cylinder temperature sensor and sensor wells
- 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
- Function check for flow rate and gravity brake
- Temperature differential control for one heat consumer
- Maximum cylinder temperature limit
- Display of the set and actual values on the BM-2 programming unit
- Integrated operating hours meter
- eBus interface with automatic energy management
- Rast 5 connection technology
- Included as standard with the CSZ-2
