Detect HVAC faults, isolate root cause, trace cascades, and show your team what to fix first — with proof attached to every alert.
A stuck valve or drifting sensor often looks “fine” in the BAS. The controller compensates, comfort drifts, and energy waste accumulates until someone gets a complaint.
SensorGuard looks for contradictions and consistency breaks between redundant signals and expected relationships, so you catch faults earlier and route the right work order.
Instead of flooding operators with threshold alarms, alerts include a concrete reason: which points disagreed, by how much, and when the pattern started.
Start with a CSV upload in 5 minutes, or connect live via BACnet/IP for continuous monitoring. No hardware purchase required.
Upload a CSV export from any BAS in 5 minutes — or deploy the collector package for live BACnet/IP monitoring with guided setup and automatic point detection.
SensorGuard's TNA engine compares every signal pair, isolates root causes from cascades, and attaches evidence to each fault. No tuning, no training data required.
Your dashboard shows faults ranked by cost impact, root cause vs. cascade, and full lifecycle — acknowledge, investigate, resolve, with history attached.
Command says 80%, position reads 5%. The actuator failed mechanically but your BAS shows no alarm — it's sending commands into the void.
Measured SAT is 68°F while setpoint is 55°F. The chiller might be undersized, the valve might be stuck, or the coil is fouled. Either way, tenants are hot and you're wasting energy.
CHW supply at 79°F when setpoint is 44°F. The chiller tripped, the lead/lag sequence failed, or the cooling tower is degraded. Cascading comfort complaints incoming.
Outdoor air damper commanded to 30% but reads 100% open. In January that's thousands of dollars in heating energy blowing through a stuck damper.
When SensorGuard alerts, it shows the contradiction that triggered it. Clear work-order language, minimal tuning, and fast time-to-value.
The result: faults that remain invisible to rule-based systems — subtle actuator failures, slow-drift control loops, masked equipment degradation — become mathematically provable. No heuristics. No tuning. No false alarms.
From the first alert to a closed work order, SensorGuard gives operations teams everything they need to act, not just know.
SensorGuard separates the primary fault from downstream effects. A stuck valve causes SAT deviation, which then causes zone complaints — the platform shows the chain, not just the symptoms.
Every fault includes a probable waste estimate so teams know what to fix first. Not all faults are equal — focus on the ones that pay off.
Acknowledge, investigate, and resolve faults with evidence attached. Full history per building so you can prove what was found and when it was fixed.
