BENEFITS
FEATURES
DESCRIPTION

In conjunction with up to six sensors residing in target zones, the microprocessor-based APS-3B 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-3B's DPDT output relay switches 24 Amp heater loads or directly operates both mechanically and electrically held remote contactors.

The adjustable hold-on timer provides up to 10 hours of heater operation after snowfall ceases, to complete snow/ice melting. Independent of weather conditions, a manual heater cycle control operates heaters for the hold-on period to clear tracked slush and drifted snow. LEDs provide indication of power, sensor status, heater operation and ground fault. Remote heater cycle and system indication is provided by RCU-1 optional accessory.

The APS-3B nonmetallic enclosure is suitable for NEMA 1 through 3R, 12 and 13 applications over an ambient temperature range of -40° to 136° F(-40° C to 58°).

For installation simplicity and low cost the sensor, CommLink and RCU-1 wiring is NEC Class 2.
