Differential Controller
This Micro Controller Based Controlleer is basically 2 channel controller, which accepts RTD Pt-100, 4Wire input(Factory set) Designed for solar water heating- forced circulation system. The Output1 - Differential Control is for A-B i.e, if the difference between the 2 input is greater than the set value the output is 'ON' & turns 'OFF' depending upon the hysterisis set, Output 2 is for 'Cold Sensor Input(B).
• Bright LED Display
• User Friendly Operation
• Display Prompts 'SnS OPn'
• 4 Wire measurement for accurate reading on long distance
