Ascon MS3D-UD Multi Solar Controller

Description 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 Automatic control of solar pool heating with one-pipe up/down collector No need to access roof for sensor replacement Real-time clock retains settings during short power failures Periodic sensing of return water temperature for heating efficiency Blackout period prevents pump operation during low solar gain hours Ideal for retrofits and controller replacements Australian-made quality and durability �� Technical Specifications Specification Details Compatibility One-pipe up/down solar collector systems Control Method Temperature sensing time-based logic Function Solar pump control with blackout scheduling Installation Type Wall-mounted, outdoor rated Power Backup Supercapacitor-backed real-time clock Warranty 3 Years �� Ideal For Pools with one-pipe solar collector systems Retrofits and replacements of older controllers Installations requiring simplified sensor access Users seeking automated, energy-efficient solar heating �� INSTALLATION GUIDE
