The Job That Falls Through the Cracks
A technician finishes a karbantartás at a client's property, logs the CO2 max and hatásfok readings on a paper sheet, leaves the signed note with the customer, and drives to the next call. Three months later there's a warranty dispute — the customer claims the unit wasn't serviced properly. The company goes looking for the record. It's on a form somewhere. Maybe filed, maybe not. The technician doesn't remember the exact hatásfok min reading at that specific address.
That's the failure this template was built to stop.
The munkalap (work order) structure captures everything the service event produces: which technician (Szerelő), which client, what job type, what was reported broken, what work was actually done, and every part number consumed. It links to an existing device record and customer record, so the work order isn't an island — it's a node in a larger service history graph.
What the Combustion Numbers Are Telling You
The CO2 Max and CO2 Min fields, paired with Hatásfok Max and Hatásfok Min (efficiency), are not optional bookkeeping. For a condensing boiler, the difference between CO2 at high fire versus low fire tells you whether the gas valve modulation is working correctly. A unit showing 9.8% CO2 at max load and 8.1% at min load on natural gas is behaving normally. The same unit showing 10.6% at max is running rich — air/fuel ratio off, potentially incomplete combustion, and a flue loss that's eating into the efficiency rating you're promising the customer.
Tracking these values per service visit, per device, is how you see a slow drift before it becomes an emergency. If you service the same boiler every year and the hatásfok max has gone from 96.2% to 94.1% to 92.4% over three consecutive visits, you know the heat exchanger is fouling despite cleaning. You have the documentation to recommend replacement before the customer calls you at midnight in January with a failed unit.
The Hőcserélő (heat exchanger) condition field — Tiszta, Átlagos, or Szennyezett — is the physical observation that contextualizes the combustion numbers. A "Szennyezett" reading alongside a hatásfok of 91% isn't a surprise. Document both. They tell the same story from two angles.
The Service History That Manages Itself
A technician is back at a Kombi boiler — a unit he last touched 14 months ago. Before walking in, he pulls the device record on his phone. Javasolt karbantartási ciklus was set to "1 év" on the last visit. The Fűtési vízszűrő was logged as Átlagos. The heat exchanger was Tiszta. There's a photo of the flue connection showing a hairline crack in the sealant that he noted in Megjegyzések as "monitor next visit."
He walks in knowing exactly what to look at. That's not luck. That's the Készülék entries link doing its job — every work order tied to the physical unit, every unit's history accessible in seconds.
The Szűrő field captures which filtration is on the system — mágneses szűrő, iszapszűrő, mechanikai Y szűrő, or whether the system uses hőcserélővel leválasztva (plate heat exchanger isolation) — because the filter configuration directly affects how quickly the heat exchanger fouls. A system with no magnetic filter on a radiator loop will sludge up a heat exchanger twice as fast as one that does. Knowing which filter type is present tells you which maintenance interval to recommend and which parts to bring on the next visit.
The Kitöltött jegyzőkönyv field captures the signed protocol as a photo. The paper exists because the customer signs it. The photo exists because the company needs the proof. Both coexist without conflict.
