Working Principle

Advantage Highlights

1. Purpose-built for thermal combustion systems with preloaded boiler/burner dedicated interface menus
2. REV203 firmware eliminates early revision flame signal reading instability defects
3. IP65 front panel withstands boiler room water splash, dust and high humidity environment
4. Resistive touch supports operation with oily work gloves without touch failure
5. Built-in long-term data logging eliminates external data recorder hardware cost

Applicable Industries

Installation Requirements

1. Cabinet panel cutout dimension strictly match factory specified outline drawing
2. Install complete EPDM sealing gasket between HMI frame and cabinet metal panel
3. 24V DC power supply must equip 2A fuse short-circuit protection
4. Signal wiring use shielded twisted pair cable, shield single-end grounded at cabinet earth bar
5. Maintain minimum 100mm ventilation clearance behind rear housing for heat dissipation

Operation & Maintenance Precautions

1. Only use neutral water-based microfiber cloth to clean touch screen, alcohol solvent prohibited
2. Firmware REV203 cannot be downgraded; cross-revision firmware flash causes permanent function loss
3. Monthly export fault log data to external storage for combustion system performance analysis
4. Avoid direct high-temperature steam blowing onto front glass panel
5. Replace EPDM sealing gasket every 2 years to prevent water ingress cabinet damage
