New replacement EXV valve won't fully close on a chiller, causing refrigerant bypass and inefficiency, despite ruling out common causes.
No software tool exists that can interface with the MicroTech III controller to diagnose stepper driver issues or adjust valve parameters from a mobile device.

- Mobile app that interfaces with chiller controllers for valve diagnostics and calibration
App Concept
ChillerEXV Diagnose
A mobile app that connects to chiller controllers via Bluetooth or Wi-Fi to test and calibrate EXV valves. It reads valve position data, commands precise steps, and identifies electrical faults like weak stepper drivers or wiring mismatches, replacing manual multimeter checks and guesswork.
Key Features
- Wireless interface to MicroTech III and common chiller controllers
- Automated EXV calibration and homing verification
- Stepper driver health diagnostic with torque estimation
- Step-by-step wiring validation guide with phase detection
Target Users: HVAC field technicians and chiller service companies managing Daikin, McQuay, and similar systems
Revenue Model: $49/mo per user subscription with a free 14-day trial
