MS3D-UD Multi Solar Controller Up-Down
Automatic Solar Heating Control with Simplified Sensor Setup
The MS3D-UD Multi Solar Controller Up-Down is a smart, year-round solution for managing solar pool heating systems using a single pipe up/down collector configuration. Designed for simplicity and reliability, this controller eliminates the need to access the roof to change sensors—making it ideal for retrofits and replacements.
Equipped with a supercapacitor-backed real-time clock, the MS3D-UD maintains critical operational data even during short power outages. It periodically checks whether water returning from the solar collector is warm enough to heat the pool, ensuring efficient energy use. A built-in blackout period prevents automatic pump operation between a variable stop time (2pm–7pm) and a fixed start time (8am), helping optimise performance and protect system components.
✅ Key Features of the MS3D-UD Multi Solar Controller
