Pulse · fault detection and diagnostics
Find the developing fault before the breakdown call.
Pulse reads how HVAC and critical equipment is running, finds developing faults, and shows the evidence. Your team uses each finding to prioritize the work, explain it to the customer, and check performance after the repair.
In plain language
What fault detection and diagnostics means.
Equipment usually drifts before it fails. A coil gets dirty, a charge leaks down, a compressor short-cycles. Pulse watches the operating data for those patterns and turns them into a finding your tech can act on.
A finding identifies a developing fault and the evidence for it. It is not a promise of the date a part will fail.
| What Pulse watches | What it can find |
|---|---|
| Supply and return temperatures, ΔT | Refrigerant and heat transfer problems |
| Superheat, subcooling, pressures | Dirty coils and airflow restrictions |
| Compressor amps, runtime, cycling | Short cycling and compressor wear |
| Setpoints, calls, sequences | Sensor and control sequence failures |
| Energy use and history | Efficiency loss and abnormal operation |
From finding to verified repair
Every finding closes the loop.
Detect→Evidence→Work order→Repair→Verified
Example data
- The evidence: the readings behind the finding and how long it has been in fault.
- The confidence: how sure Pulse is, stated on the finding.
- The next step: what the tech should check, with the manual page when it's on file.
- Verification: after the repair, the same data shows whether the fault is gone.
Getting started
What a first Pulse job needs.
- Equipment: HVAC and critical equipment at a customer you already maintain, starting with a few rooftop units.
- Inputs: operating data from sensors and controllers on each unit. The MIS design tool determines what each unit needs.
- Setup: your team installs, and MIS programs and commissions through its AI factory (automated tools that write most of the controller programming from the design, finished and tested by MIS engineers).
- Reporting: findings and outcomes in a customer portal with your company's name on it.
