Alderon Duplexor™ Indoor Alternating Sump Pump Duplex Control Panel
The Alderon Duplexor™ is a compact alternating pump controller for indoor applications designed for reliable duplex (two-pump) control in sump pump and other indoor lift station applications. It automatically alternates the lead pump each cycle to equalize runtime and extend pump life.
This specific configuration includes (2) Altra™ Gold Series mechanical float switches with 20 ft cords — one for pump On/Off control and one for high-level alarm. If the liquid level reaches the high-level sensor, the alarm activates and both pumps start (if the combined draw is below 12 amps). If the total exceeds 12 amps, the pumps will alternate operation instead.

KEY FEATURES
- Automatic pump alternation – Switches lead pump each cycle for balanced wear.
- Works with automatic + manual pumps – Flexible for use with any style of 120VAC submersible sump pump.
- Real-time amp monitoring – Displays running amps (not just startup amps) for each pump. Supports dual-pump operation when both pumps draw under ~12 A running.
- Pump exercise interval – Programmable 1–99 days. Briefly runs an idle pump (typically ~3 seconds) to prevent locked-rotor conditions after long inactivity.
- High/low amp thresholds & extended-run alarm – Configurable amp limits and extended running protection with alarms.
- Statistics tracking – View pump cycle counts, run data, and high-level event history.
- Force-run capability – Manually force a pump to operate when needed.
- Compact design with clear status display, intuitive menu navigation (arrow keys + enter), and test/silence functions.
