AIWA EVI H Outdoor

Compact air-water heat pump with or without capacity regulation for indoor or outdoor installation

Compact outside or inside installed air-water heat pump. Versions designated "i" are equipped with an integrated capacity control. Depending on the type of maximum flow temperature of up to 65 ° C. Compact design, integrated control cabinet with control.

Closed cooling circuit with Copeland Scroll compressor and heat exchangers. When capacity control variants with build in frequency inverters. Wide application possibilities of heating and cooling of houses and water heaters. Active cooling is reversible standard possible. Easy installation without complicated wiring and installation of refrigeration. Optimized for low temperature heating systems not only in new construction but also for heating systems with mid temperature flow after renovations.

Frame construction with solid base plate on adjustable feet. Epoxy-coated panel of the base unit. With weather-compensated, digital heat pump control. To control a heating circuit with mixer and one heating circuit without mixer.

Plain text user guidance with function-dependent menu levels, information texts and states in plain text. Diagnostic system with history storage and output state indication. Outdoor temperature sensor, hot gas sensor, liquid refrigerant sensor, heat pump flow temperature sensor and return temperature sensor, as well as source-flow sensor, source return sensor and DHW sensor included.

Optionally available with ModBus module as well WebControl control and monitoring via the Internet.
