APS Control Panel

The ETI APS-3C provides effective, economical automatic control of snow melting applications for walkways, ramps, driveways, gutters and downspouts. Operating at either 120 volt or 208-240 volt, 50/60 Hz, the APS-3C's DPDT output relay switches 24 Amp heater loads or directly operates both mechanically and electrically held remote contactors. The APS-3C is interchangeable with earlier APS-3 models. New functions available with the APS-3C include a relay interface for use with energy and building management systems and a high limit temperature sensor adjustable from 40 deg F to 90 deg F (4 deg C to 32 deg C) to protect heating cable from excessive temperatures.

The ETI APS-4C provides effective, economical automatic control of snow melting systems including those for gutter and down spouts. Supply voltage options include 240 volt single phase or 208, 277 and 480 volts 3-phase, with a contactor rating of 50 amps per pole. The integral 30 mA ground fault circuit interrupter with a test/reset facility ensures safety along with NEC and local code compliance. The APS-4 operates up to ten SC-40 Satellite Contactors for larger loads. New functions available with the APS-4C include a relay interface for use with energy and building management systems and a high limit temperature sensor adjustable from 40 deg F to 90 deg F (4 deg C to 32 deg C) to protect heating cable from excessive temperatures.
