About
NADKOS SM is an internal field-service reference tool for SPRSUN heat pump technicians.
It cross-references parameters from the Heat Pump with the physical sensors, inputs, outputs, and wiring diagrams on the unit, so a technician can go from a parameter reading on-site straight to identifying the right sensor and its location, without paging through a paper manual.
Included for every supported unit type and model:
- Parameter reference: sensor and output identification, expected values, and confidence notes
- Fault code lookup with recommended solutions
- Reference diagrams and field photos
- Source documents (manuals, schematics) attached per model
Content syncs from the NADKOS service backend and is cached on-device, so it stays usable with a weak or no signal in the field. Sign-in is required and is limited to technicians provisioned by NADKOS; this app is not intended for general consumer use.
