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
CTU controller – PYRO-STAG

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

• 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

• 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
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 DeIcing 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
