How AC Lock eliminates waste for businesses
Control your ACs — from day one
Buy device once. Free software forever. No recurring fees needed.
Auto schedule lock
Set on/off times for each AC. System auto-shuts on schedule — even offline.
Temperature lock
Set standard temp (e.g. 25°C). Staff cannot set lower — blocked at device level.
Electricity cost in VND, real-time
Each AC shows running cost in VND (live EVN rates) — not abstract kWh.
Unauthorized action counter
System counts override attempts + total waste. You see "this month: 47 times · 4.2M VND". Details per action — upgrade tier.
Remote control
Turn on/off/adjust ACs from your phone — even from home. No need to visit the store.
Full action history
Who turned on, off, adjusted temp — all recorded. No hidden actions.
Like a family medicine cabinet: Like a family medicine cabinet: you have tools to handle problems when they arise. Schedule lock + temperature lock block the 2 biggest waste sources. See a problem, fix it yourself — quick and simple.
But no records to look up later. But no records to look up later. After 3-6 months, you can't tell "how was this issue resolved", "who was responsible", "how many times did it recur". When you need full operational records — like medical records — upgrade to Resolution Enforcement (see below).
This is not an investment — it's patching a leak
A pipe leaks 24/7. Would you ask "how long until the repair pays for itself?" No. You just patch it because every day you don't, money flows out.
AC waste is exactly the same. AC Lock doesn't "generate profit" — it blocks the leak.

4 problems Device + Free Software solves
Forgotten after-hours shutoff
End of shift is busy serving customers — AC shutdown is not the priority.
→ Schedule lock auto-shuts on time
Temperature set to 18-20°C
Staff lower temps unsupervised — no one monitors per-unit electricity cost.
→ Temperature lock blocks at device level
Data blindness
Bills don't break down cost per AC — can't tell where to optimize.
→ Per-unit cost in VND, real-time
Late failure detection
No early warnings — small issues compound into expensive repairs.
→ Alerts when AC behaves abnormally
