Type SLC-C

Shipco® Logic Controller for Condensate

Control Systems & Panels

The Shipco® Type SLC-C is an economical method of automating functions on a Shipco® condensate unit. The SLC-C can monitor receiver status locally and remotely. Continuous level and temperature readings are sent to the SLC-C enabling it to perform various functions such as display status, read level set points, signal alarms, control pumps on a condensate unit. A separate method of pump alternation is not needed. The SLC-C is a programmable NEMA 4X controller featuring a full color touchscreen display. Support for building automation protocols including Modbus and BACnet are available.

If you have existing float switches or prefer to use them, the SLC-C will provide run status of pumps, trigger an alarm if a high-water float switch is available, and read temperature if a separate thermocouple is provided.


  • Live graphical and numeric indication for water level and temperature via the Shipco® Transmitter.
  • Operates up to 3 pumps.
    • Alternating control — Automatically changes lead pump on each cycle.
    • Manual control — LEAD-LAG(-LAG2)-OFF selector switch.
    • Test button bypasses control sequence to energize pumps until button is released.
    • Pump graphics change color to indicate status (Green = ON, Red = FAULT, Grey = INACTIVE).
    • Run Cycle Timers with manual reset.
  • Failure indication and protection.
    • High water alarm indicates overflow.
    • Low water alarm indicates leaking tank.
    • High temperature alarm indicates traps failed open.
    • High temperature shutoff protects pumps from cavitation.
    • Automatically adds cooling water to maintain operating temperature (optional).
    • Alarm ledger automatically logs any irregular operating conditions.
    • Loss of sensor signal indicators.
