Smart Energy Saving: How the Isotherm ECO Function Works

One of the most valuable features of the Isotherm Freeline 115 Elegance is its smart control panel. The integrated ECO function operates as an intelligent over-cooling system designed to protect your marine leisure batteries.

When your engine is running, or when your boat is plugged into shore power, the fridge senses a surplus of electricity. It automatically lowers the cabinet temperature to freeze-store thermal energy within your food and drinks. When you switch back to relying entirely on your battery bank, the compressor throttles down, utilizing that stored cold energy to dramatically reduce its overall power draw over a 24-hour cycle.

Troubleshooting via the Integrated Blinking Code System


No one wants their food spoiling while out at sea or on the road. The Freeline 115 Elegance includes an integrated diagnostic system. If the fridge experiences an operational fault, the internal LED display will flash a specific sequence of blinking codes.

This allows boat owners to immediately diagnose issues—such as low voltage drops, compressor over-speed, or fan errors—without needing to instantly pull the unit out of its housing.

Isotherm Freeline 115 Elegance – FAQs

What are the dimensions of the Isotherm Freeline 115 Elegance?


The Isotherm Freeline 115 Elegance measures 797mm in height, 525mm in width, and 495mm in depth. Weighing 22.3 kg when empty, its relatively slim profile and wide-set internal layout allow it to integrate smoothly into compact marine galleys and recreational vehicle cabinet spaces.

What is the power consumption of the Isotherm Freeline 115?

The Freeline 115 consumes roughly 267 Wh over a 24-hour period under standard operating conditions. Powered by a highly efficient 12/24V Secop/Danfoss compressor, its power draw can be minimized further by engaging the control panel’s built-in, over-cooling ECO energy saving mode.

How does the Isotherm Freeline 115 ECO mode save battery power?

The ECO function activates an intelligent over-cooling cycle when a surplus of electricity is detected (such as when your boat engine runs or hooks up to shore power). It stores cold energy directly within your food and drink provisions, keeping power draw to a minimum later on when running purely off your battery banks.

What compressor does the Isotherm Freeline 115 use?

The Freeline 115 Elegance runs on a premium Secop / Danfoss BD35F 12/24V direct-current compressor. This fan-cooled unit is widely considered the industry standard for marine applications due to its exceptionally quiet operation, high cooling efficiency, and reliability under tilting or rocky conditions at sea.
