PYRO-STAG

De-Icer Optimizer Controller

Technical presentation

2013

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 STRUCTURE

Outputs To 4 De-Icing Heaters

Zone 1

Zone 2

Zone 3

Zone 4

ANY SNOW SENSOR CONTROLLER

OUTPUT to HEATERS

24VAC supply

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

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

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
