Legacy Home Automation

Older Home Automation Systems Are Still Worth Understanding.

Before replacing an older home-control system, let us determine what you have, what’s wrong with it, and whether it can be repaired or practically modernized.

We Service Technology Other Companies Have Left Behind.

Many homes have sophisticated control systems installed 15, 20, 30 or even 40 years ago. The original manufacturer may be gone, replacement parts may be difficult to find, and many current automation companies would rather replace the entire system than troubleshoot it.

That’s where Chaparral Controls is different. We understand both legacy home-control technology and today’s systems. Our first objective is to understand what you already have and determine the most practical way to keep it working.

Unity Systems Home Manager

Introduced in 1985, Home Manager combined zoned temperature control, security and fire alarm functions, and lighting and appliance control in one integrated system operated from a 14-inch touchscreen.

Approximately 8,000 systems were installed through about 120 dealers nationwide before Unity Systems ceased operations following its sale in 1999.

Chaparral Controls understands these systems. We can troubleshoot existing installations, repair serviceable components, and help homeowners evaluate sensible upgrade options.

We Know What’s Behind the Touchscreen

Service, Repair, Upgrade and Modernize.

The original proprietary touchscreen and the main control-panel power supply are among the Home Manager system’s principal weak points. We can help determine whether a problem can be repaired within the existing system or whether an upgrade path will provide better reliability, usability and remote access.

Diagnose FirstIdentify the actual failure before recommending replacement.
Preserve What WorksKeep useful infrastructure when doing so is practical.
Modernize SelectivelyImprove control and reliability without replacing more than necessary.

What’s Inside

Understanding the electronics inside the enclosure is essential to diagnosing and servicing the system properly.

We Start by Figuring Out What’s Wrong.

Older does not automatically mean obsolete. We diagnose first, then recommend the repair, upgrade or modernization path that makes sense.
