SmartECO: Intelligent Off‑Grid Cooling

A key feature of FJZ7 air conditioners, unlocked when paired with Tempra battery. SmartECO intelligently adjusts your RV air conditioner’s power use based on available battery energy—extending off-grid runtime, protecting your battery, and prioritising onboard power needs. Reliable cooling for longer, wherever you park.

The Off-grid AC Solution

Experience the future of air conditioning in RVs. The Dometic FJZ series of roof air conditioners has been developed to meet the highest demands - smarter, quieter, more comfortable, and more environmentally friendly than ever before. Made from recycled plastic and equipped with our most powerful compressor yet, the updated FreshJet FJZ series succeeds the previous FJX range and delivers impressive performance while consuming little energy. With a 5-year warranty as standard and serious capacity—up to 3500 W of it—the FreshJet FJZ series cools even the biggest rigs on the hottest days, wherever the road takes you.

Clever Tech

SmartECO continuously monitors the Tempra battery’s state of charge while the FreshJet FJZ7 runs through a sine-wave inverter. Adjusting the compressor output, reducing cooling power, switching to fan mode, or pausing operation to manage energy use. Once battery levels recover, the system automatically restores full cooling performance. The result? Your AC running for 30% longer off-grid than before.

Features

STAY CHARGED UP.

Peace of mind is built in with SmartECO. As battery charge levels drop, SmartECO reduces A/C power to prevent deep discharge and optimise battery cycles. Meaning longer battery life and reliable off-grid cooling without unexpected shutdowns.

GET CONNECTED. ANYWHERE.

Monitor and control all functions of the FJZ7 AC from your smartphone. With WiFi connectivity for control via the Dometic Power App, switch on your air conditioner on your way back from the restaurant or beach. Comfort is always within reach.
