How Electrical On-Delay Staging Relays Work

By Dave Rongey Summary: This section will cover the use of relays that are sometimes needed to control special device loads such as Air Conditioners and other high demand equipment from starting at the same time. © By: Dave Rongey

Problem Solvers for Air Conditioners - Energy Savers for Large Electrical Loads

This method will help prevent nuisance tripping of sub-feed circuit breakers and reduce the electrical demand on your utility service which could lead to much higher energy bills.

Introduction:
ICM100/101 DELAY ON MAKE.
• 3 or 5 minute fixed.
• Works with anticipator thermostats.


MODE OF OPERATION:
When power is applied to the input, the time delays begins. After the time delay is complete, the load energizes and remains energized as long as power is applied. The control is reset by removing power during or after the time delay period.

2-Wire Compressor Staging/Startup Delay Timer:

SPECIFICATIONS Input: • Voltage: 18-30 VAC • Frequency: 50/60 Hz Output: • Output Ratings: – Maximum: 1.5 amps – Minimum: 40 mA – Inrush: 15 amps Time Delay • 3 or 5 minute fixed
