Retail
Know which fridge or AC is failing or burning money — before customers complain.
Hundreds of stores, each with a few ACs, a few fridges, lights and signage. BenKon shows your operations team what is happening at every unit in every store — and turns every issue into a task with an owner, verified when it's done.
For: Head of chain operations · Technical lead (M&E)
The problem
- A fridge fails overnight; by morning the stock is already spoiled.
- ACs and fridges keep running after the store has closed.
- Hundreds of stores, and no way to tell which one needs a technician first.
Cost & risk
- Stock spoils when temperatures drift out of range and nobody knows.
- Run-hours outside opening hours — electricity that earns no revenue.
- Technicians arrive at the wrong place at the wrong time; small faults grow into big repairs.
How BenKon handles it
- 1 · Detect
Alerts the moment a fridge runs warm; spots compressors that never rest, weak outdoor units, and units running after closing.
- 2 · Assign & track
Every issue becomes a task tied to the store and the unit, assigned to the right person. Technicians receive the task with a checklist; some faults are fixed remotely, such as switching or resetting schedules. Managers see which tasks are closed, which are open, and which stores keep repeating.
- 3 · Verify
The system reads the data again after the fix to confirm the unit is back to normal.

Services
Know which outdoor unit stopped and which zone is too warm — before members complain.
Service chains run high-capacity AC all day across several floors and zones. Customers feel the temperature before the technical team does. BenKon tells you which unit stopped or is running weak, with a checklist, and follows it until it's fixed.
For: Service chain managers · Technical lead
The problem
- A VRV outdoor unit stops, and you only find out when members complain about the heat.
- One zone too warm, another too cold — adjusted by hand all day.
- There's solar, but no one knows how much it actually offsets.
Cost & risk
- Complaints and bad reviews when workout or service areas get hot.
- Units over-cooling empty zones.
- No way to measure the return on the solar investment.
How BenKon handles it
- 1 · Detect
Spots outdoor units that stopped or run weak, and zones outside the target temperature band.
- 2 · Assign & track
The task is tied to the zone and the unit, and sent to a technician with a checklist. Some faults are fixed remotely, such as restarting an outdoor unit; the rest are fixed on site. Managers follow it until it's closed; solar output sits next to consumption, hour by hour.
- 3 · Verify
Power and temperature are read again after the fix to confirm the unit is running normally.
Devices monitored
Real example · 29/09/2026 · Southern Vietnam
VRV outdoor unit stopped
Detected
Automatic diagnosis: VRV outdoor unit stopped, at a site running a VRV system.
On site
Indoor units blowing air but no cooling.
Action
Outdoor unit restarted remotely.
Outcome
Verified: the unit is running normally again.
Schools · public sector
Measure, manage and transparently report electricity savings — with Vietnamese technology.
Schools, hospitals and public agencies have annual electricity-saving targets but rarely the tools to measure and prove them. BenKon switches ACs by timetable, compares buildings and rooms, and catches rooms left running — with data you can report.
For: Facilities management · Estates office · Project management units
The problem
- Classroom ACs left on after lessons end.
- Many buildings, and no way to tell which building or room is costly.
- The timetable keeps changing; on/off schedules can't keep up.
Cost & risk
- Electricity spent on empty rooms after lessons.
- Savings are hard to prove with measured data.
- Assets aren't monitored once the investment is made.
How BenKon handles it
- 1 · Detect
Spots rooms where the AC was left on after lessons and rooms running outside the timetable.
- 2 · Assign & track
Alerts go to the right building and the right facilities officer. Automatic on/off by timetable; forgotten rooms switched off remotely. Periodic reports by building and room — usable for electricity-saving reports.
- 3 · Verify
Measured data confirms units are off and building consumption drops on time.

Healthcare
Equipment rooms, storage fridges, air conditioning — monitored 24/7, fixed before patients are affected.
Hospitals, clinics and diagnostic centres run continuously, with equipment that cannot be interrupted. BenKon fits measurement devices without touching the equipment, monitors air conditioning, equipment-room temperature, storage fridges and energy; every issue goes to the right person and is verified after the fix.
For: Operations heads of clinic and diagnostic chains · Hospital facilities management · Technical leads
The problem
- Issues happen when no one is on shift: who knows, who fixes?
- Storage fridges drift outside 2–8°C without anyone noticing in time.
- Equipment-room incidents: hard to prove whether cooling or power was the cause.
- Incident information scattered across logbooks and messages.
Cost & risk
- Scans and appointments disrupted when equipment rooms overheat.
- Medicines and biologicals discarded when storage temperature goes out of range.
- Missing records when explaining incidents to regulators or equipment suppliers.
How BenKon handles it
- 1 · Detect
24/7 monitoring of air conditioning, temperature and humidity in equipment and server rooms, storage fridges and energy; early signs such as fridge defrost cycles getting longer.
- 2 · Assign & track
Alerts reach the technician on duty; if not handled in time, the manager is notified. Air conditioners running after hours switch off automatically where permitted.
- 3 · Verify
Measurements are taken again after the fix to confirm temperature and power are back within range; incidents are recorded and reported per site and per unit.
Devices monitored
At each air conditioner: metered at the breaker, controlled like a remote
A clamp meter sits after the breaker in the distribution board — no cutting circuits, no opening the unit. An infrared controller near the indoor unit works like a remote, so installation is quick and the manufacturer's warranty is unaffected.
Equipment rooms: monitoring only, no interference with medical equipment
Clamp meters on the breakers of imaging equipment and equipment-room cooling; the BenKon enclosure sits outside the board. Power over time flows to the platform with alerts on anomalies — and serves as evidence when finding the cause of an incident.

Typical scenario: a 2–8°C storage fridge
Defrost cycles getting longer are often an early sign of an iced-up evaporator, fan or heater problem — before the temperature passes 8°C. BenKon alerts on this early sign, assigns the task to the owner and verifies once the temperature is back in range.

Offices · buildings
AC and lights run only when people are there — energy by floor, zone and hour.
Empty meeting rooms stay cold, a whole floor runs for a few people working late, and the bill is a single number. BenKon connects occupancy sensors, ACs, lighting circuits and meters into one operating loop: see it, switch it off, verify it, report it.
For: Building managers · Office administration
The problem
- Empty meeting rooms with AC and lights on.
- A few people working late, and the whole floor's AC running.
- One number on the bill, and no idea which floor costs most.
Cost & risk
- Electricity for empty rooms and unoccupied zones.
- Whole floors running after hours for a few people.
- No way to allocate electricity cost by floor or department.
How BenKon handles it
- 1 · Detect
Spots unoccupied zones with AC or lights on, and units running outside working hours.
- 2 · Assign & track
Alerts go to building management by floor and zone. ACs and lights switch off automatically when a zone empties; after-hours running is blocked. Energy reports by floor, zone and hour to allocate cost and adjust operating policy.
- 3 · Verify
Sensor and meter data confirm the zone is off.
Devices monitored
Hotels
Empty rooms don't run AC; weak units are caught before guests complain.
Guest experience depends on an AC that works; cost depends on whether empty rooms switch off. BenKon tracks every room — run-hours, energy and actual temperature — and turns every issue into a task for the engineering team.
For: Hotel general managers · Chief engineers
The problem
- Empty rooms with the AC on.
- Guests complain a room isn't cool, while the unit has been weak for a long time.
- No visibility of run-hours and energy per room.
Cost & risk
- Electricity for rooms with no guests.
- Bad reviews when rooms aren't cool.
- Emergency repairs when a unit fails in peak season.
How BenKon handles it
- 1 · Detect
Spots empty rooms with units running, and rooms too warm even with the unit on.
- 2 · Assign & track
Tasks go to engineering with the room number and unit. Units are adjusted remotely where appropriate; technicians check weak units in the room. Energy and run-hours per room, per day; which rooms keep repeating.
- 3 · Verify
Room temperature and unit power are read again after the fix.
Devices monitored
Real example · 05/10/2026 · Central Vietnam
Room above the heat threshold
Detected
Automatic detection: room temperature above the hot threshold, repeated over 2 days.
On site
Unit blowing air but no cooling.
Action
Unit switched on and held on remotely.
Factories · warehouses
Track load and efficiency of every large unit; maintain when the machine actually needs it.
High-capacity cooling for production floors, warehouses and offices runs across multiple shifts. When a unit overloads or fails mid-shift, the cost is productivity. BenKon tracks the load and efficiency of every unit so maintenance acts on the right machine at the right time.
For: Plant managers · Maintenance leads
The problem
- Large units overload and fail without warning mid-shift.
- Maintenance follows a fixed calendar, not the machine's real condition.
- Hot production areas hurt productivity.
Cost & risk
- Production disruption when a unit fails unexpectedly.
- Maintenance spent at the wrong time on the wrong machine.
- Lower productivity in hot production areas.
How BenKon handles it
- 1 · Detect
Tracks load and efficiency per unit; spots overloaded or wasteful units.
- 2 · Assign & track
Tasks go to the maintenance team with the unit and area. Condition-based maintenance on the units that need it. A history for every unit to plan replacements.
- 3 · Verify
Load and temperature data after maintenance confirm the unit is back to normal.
