ETO 2-4550 thermostat is used for: frost protection control of roof gutters and downpipes; frost protection control of steps, entrances, driveways, parking lots, ramps, sideways and bridges.
ETO2-4550 is a programmed microprocessor controller for ice and snow melting systems. It controls two independent zones according to the data from two separate sensors (one roof sensor ETOR-55, ETF-744/99 and one ground sensor ETOG-55) or two similar sensors (2 roof sensors ETOR-55, ETF-744/99 or 2 ground sensors ETOG-55). Optimal operation is ensured, thanks to output control which makes the system effective and economical. The thermostat is DIN rail – mounted in panel or wall – mounted with a cover box.
Additional functions: control of electric or water-based ice and snow melting systems, efficient control – minimising energy consumptions, alarm relay with external signal, time extension of residual heating and language options.
Remote control: ETO2 thermostat can be controlled from a distance via external signal: system: switch ON/ OFF, or heating period extension switch ON option.
Used for: frost protection on roof gutters and downpipes; frost protection of steps, entrances, driveways, parking lots, ramps, sideways and bridges.
