PYRO-STAG De-Icer Optimizer Controller: Efficient and Flexible Snow De-Icing Solution

The Meitav-tec PYRO-STAG De-Icer Optimizer Controller introduces a revolutionary approach to snow de-icing. Compatible with existing systems, it features an energy-saving algorithm, simple installation, and a user-friendly interface. Its modular design allows for effective sequencing between up to four zones, enhancing area coverage with limited power supply. With adjustable cycle times, delay settings, and straightforward DIP switch configurations, this controller optimizes performance while reducing energy consumption, making it an ideal solution for demanding installations.

  1. PYRO-STAG De-Icer Optimizer Controller Technical presentation 2013

  2. Introduction • Meitav-tec is introducing a new concept of De-Icing control • Featuring: • Works with any existing De-Icing system • Energy saving algorithm • Simple and quick installation • Simple, Logical & accessible user Interface • Sequencing between zones allowing larger area coverage with limited power supply • Modularity – 1 to 4 contactors

  3. CTU controller – PYRO-STAG

  4. SYSTEM STRUCTURE 24VAC supply ANY SNOW SENSOR CONTROLLER OUTPUT to HEATERS Outputs To 4 De-Icing Heaters Zone 1 Zone 4 Zone 2 Zone 3

  5. System Features • Steady power supply or Sequencing / Staggering between output zones • Sequencing / Staggering - 1/2/3/4 or 1+3/2+4 • Adjustable Cycle time between zones • Off Delay Time - Adjustable in cycles count • Adjustable OFF Delay cycles • Override operation – activates the system CTU information • 24VAC operated • DIN RAIL or screws wall mounting • Dimensions: 8 x 4 x 2 inches (205 x 96 x 60 mm) Weight: 1 lb. (0.545 kg.) • Flammability UL94V-0 • IP 20

  6. Electric Layout

  7. Operation Scenario # 1 • 4 zones works in staggering with OFF delay Zones 1 2 3 4 1 2 3 4 De-Icer ON input End Of Delay Time Start Delay OFF Time INDEX: Zone Output ON Zone Output OFF Input from De-Icer

  8. Operation Scenario # 2 • 1 Zone works constantly • 3 zones works in staggering • OFF delay Zones 1 2 3 4 1 2 3 4 De-Icer ON input End Of Delay Time Start Delay OFF Time INDEX: Zone Output ON Zone Output OFF Input from De-Icer

  9. Operation Scenario # 3 • 4 Zone works in staggering • Every 2 zones are working together • OFF delay Zones 1 2 3 4 1 2 3 4 De-Icer ON input End Of Delay Time Start Delay OFF Time INDEX: Zone Output ON Zone Output OFF Input from De-Icer

  10. Configurations selection • Simple DIP Switch positions define all options • Easily modified by technician on site ON ON 1 2 3 4 5 6 7 8 1 2 3 4 • S1-1 - # of outputs work in staggering - 2 or 4 • S1-2 - Outputs linkage - outputs 1 & 3 and 2 &4 are linked or • outputs 1, 2, 3, 4 works separately • S1-3+4+5 - Sequence step timer - 1, 5, 10, 20, 30, 45, 60, 120 min. • S1-6 - Delay between outputs On/Off activation • S1-7+8 - Off Delay # of cycles - 0, 1, 2, 3 delay cycles • S2-1 - Device Enable/Disable - when disable = all outputs ON

  11. Summary • The Meitav-tec De-Icing Sequence device offers solution for installations with large power consumption as it allows to divide power supply to separate zones • The PYRO_STAG controller can be used with any existing De-Icing system • Simple installation and easy configuration will minimize cost • Energy saving algorithm staggering between zones allows large area coverage with lower power consumption • Professional Service and JIT availability
