- 5. System components • 24VAC supply from controller • Igloo shape design • Conduit connection •Adjustable rust proof arm – up to 20 inches length • Anti birds nesting solution Snow Sensor + mounting Fixture
- 6. System components Controller • 24VAC operated • Inputs: • Meitav-tec Snow sensor (up to 4 sensors) • 3rd Party (existing) Snow sensor • Upper Limit Temperature sensor • Outputs: • 4 Zones On/Off heaters control • 1 Gutter On/Off heater control • LCD backlit display with operation indications • User Friendly Technician Settings parameters
- 7. System components Controller Features • Sequencing / Staggering 4 zones • 1/2/3/4 or 1/2/3 or 1+3/2+4 • Adjustable Cycle time between zones • Outputs status real time indication • Disabling zones • De-Icing Temperature Set-Point • Upper Limit Temperature Set-Point - Adjustable • Off Delay Time - Adjustable • Selectable operation modes – Off/On/ Automatic •Override operation – activates the system once for a configurable period of time •Alarms and Sensors Errors indications
- 8. System components UL Temperature input • Isolated sensor • Stops the operation when the heated surface reach a intended (Technician adjustable) temperature value • Semi Rigid – can be pushed into conduit • 10 meters (30 feet) cable length • Installed in the surface plenum
