Macromatic LCP2C100 HVAC Control Relay 120V Dual Pump Up

SKU CH-CZ3Z-D3N66

Controls liquid level with dual-probe pump-up logic at 120 V AC and 10 A rating

  • Controls two pumps with one relay
  • 120 V AC input suits standard mains supply
  • SPDT contacts rated 10 A at 240 V AC
  • Adjustable sensitivity from 700 Ω to 100 kΩ
  • LED status indicator shows relay state

HVAC Level Control Relay

The Macromatic LCP2C100 is a level control relay designed for HVAC systems that require automated liquid-level management. It operates on a 120V AC supply and uses a dual-probe arrangement to detect conductive media. The unit mounts in an 8-pin octal socket and provides a visual LED status indicator for quick diagnostics.

Suits Single-Pump-Up Applications

This relay suits installers who need a pump-up function with adjustable sensitivity between 700 ohm and 100, 000 ohm. It is not for systems requiring pump-down control or configurations that demand more than two probes. Buyers needing a different contact form or a non-octal mounting style should look at alternative models.

Handles 10 A Resistive Loads

The SPDT output contacts are rated for 10 A at 240V AC and 7 A at 28V DC, giving comfortable headroom for typical fractional-horsepower pump motors. The relay runs out of capacity when the load exceeds these current limits or when the control voltage differs from the specified 120V AC input.

Highlights

  • Controls two pumps with one relay
  • 120 V AC input suits standard mains supply
  • SPDT contacts rated 10 A at 240 V AC
  • Adjustable sensitivity from 700 Ω to 100 kΩ
  • LED status indicator shows relay state

Questions about this item

What power supply must already be available for the 120V AC input?

A 120V AC source is required to power the relay coil and the probe circuit.

Can the 10 A @ 240V AC contacts switch the same loads as my existing 28V DC circuits?

The contacts are rated 10 A at 240V AC and 7 A at 28V DC, so the DC rating is lower than the AC rating.

How does the LED indicator confirm the relay is operating correctly?

The built-in LED lights when the output contacts are energised, showing the pump-up function is active.
