Solar control module, type SM1

Included in the standard delivery of the Vitodens 242-F.
Assembly
The solar control module contains:
■ PCB
■ Connection terminals for:
– 2 sensors
– Solar circuit pump
– KM BUS
– Power supply (on-site ON/OFF switch)
■ PWM output for controlling the solar circuit pump
The standard delivery includes collector temperature sensor and cyl-
inder temperature sensor.
