Solar Control Module, Type SM1.
Function extension inside enclosure for wall mounting.
Electronic temperature differential control for dual mode DHW heating and central heating backup using solar collectors.
Details:
- With output statement and diagnostic system
- Operation and display via the Vitotronic control unit
- Heating of two consumers via a collector array
- Second temperature differential control unit
- Thermostat function for reheating or utilising excess heat
- Speed control for solar circuit pump with PWM input (Grundfos and Wilo)
- Suppression of DHW cylinder reheating by the heat generator subject to solar yield
- Heat-up of the solar preheating stage (with DHW cylinders from 400 litre capacity)
- Complete with documents
Notes:
Order immersion temperature sensor, part no. 7438702, if the following functions are required:
- For DHW circulation diversion in systems with 2 DHW cylinders.
- For return changeover between the boiler and the heating water buffer cylinder.
- For heating additional consumers.
