Wolf SM2-2 solar module 2745869

Expansion module for controlling a solar power system with up to 2 storage tanks and 2 collector arrays

• Easy configuration of the controller by selecting predefined system variants.
• In conjunction with Wolf heating appliances, higher energy savings are achieved through intelligent storage tank recharging, i.e., blocking storage tank recharging when solar yield is sufficiently high. Heat quantity measurement is achieved with an external sensor.
• Heat meters for all configurations
• Functional check for volume flow and gravity brake
• Selection of storage operating mode (priority, subordination and parallel operation)
• Display of target and actual values ​​in the BM2 operating module
• eBus interface with automatic energy management
• Rast 5 connection technology
• Immersion sensor PT1000
• For collector immersion sensor 5K NTC for storage tank
• Storage immersion sleeve DN 15 (1/2") with PG strain relief
• Collector immersion sleeve DN 20 (3/4") with PG strain relief and seal
