HVAC HOST

Built for Extreme Cold — Full-Capacity at -41°C, Zero Derating at -15°C

Equipped with Enhanced Vapor Injection (EVI) technology, the system maintains 100% rated heating capacity at ambient temperatures as low as -15°C with zero derating. In extreme conditions between -35°C and -41°C, the compressor continues to operate without shutting down, providing uninterrupted heating throughout the entire heating season — with no need for auxiliary electric resistance backup.

The integrated intelligent frost-free / gliding defrost system minimizes defrost cycle duration and heating capacity loss. Suitable for northern continental climates, high-latitude regions, and high-altitude installations.

Heat Recovery — 100% Waste Heat Captured in Cooling Mode, Free DHW All Summer

In cooling mode, all condenser waste heat is redirected through the heat recovery module to produce domestic hot water at zero additional energy cost. System combined COP (heat recovery mode) reaches 7.38*. During winter, the system equally delivers efficient DHW production by extracting heat from ambient air, resulting in significantly lower annual energy consumption.

LONG/SHORT PRESS CONTRO	TOUCH SCREEN CONTROL

Comprehensive Safety — No Open Flame, No Gas Risk, Full Water-Electric Isolation

The hydraulic circuit and electrical system are completely isolated by design, eliminating leakage risk at the source. No open flame, no combustion process — completely eliminating the risks of gas leaks and carbon monoxide poisoning.

Ideal for markets with stringent residential safety requirements and regions actively phasing out fossil fuel heating (e.g., countries operating under the EU Energy Performance of Buildings Directive, EPBD).

Ultra-Low Noise Operation & Rapid Temperature Response

Multi-stage acoustic isolation design keeps operational noise as low as 40–50 dB(A), ensuring a disturbance-free living environment.

Under moderate climate conditions (outdoor temperature ≥ 5°C in winter / ≤ 35°C in summer), the system achieves a significant temperature rise (≥ 8°C) or drop (≥ 10°C) within 20 minutes, reaching comfortable room temperature rapidly. Actual performance varies by floor area, building insulation level, and orientation.
