Advanced Settings & Features

Explore modulating output for efficiency‚ customize frost protection settings‚ and understand boiler reset procedures for optimal performance and tailored heating control.

Modulating Output

The Ideal Logic Combi 35 utilizes modulating output‚ a sophisticated feature that optimizes boiler performance and energy efficiency. Unlike traditional boilers operating at fixed output levels‚ this system dynamically adjusts the burner’s gas supply based on the actual heating demand. This means the boiler only produces the precise amount of heat required to maintain the desired room temperature‚ minimizing energy waste and reducing gas consumption.

This intelligent control ensures consistent comfort while lowering heating bills. The boiler’s control panel displays the current output level‚ allowing users to monitor its operation. Modulating output also contributes to quieter operation‚ as the burner isn’t constantly running at full capacity. It’s a key component in achieving a more sustainable and cost-effective heating solution.

Frost Protection Settings

The Ideal Logic Combi 35 incorporates robust frost protection settings to safeguard your heating system during cold weather. These settings are crucial for preventing frozen pipes and potential damage‚ especially during prolonged periods of sub-zero temperatures. The boiler automatically activates when the central heating temperature drops below approximately 5°C‚ circulating warm water through the system to maintain a safe temperature.

Users can typically adjust the frost protection setting via the control panel‚ though factory defaults are generally sufficient. It’s important not to disable this feature‚ even during milder winters. Additionally‚ ensure adequate insulation of exposed pipes to further minimize the risk of freezing. Regular checks of the system before and during cold snaps are recommended for optimal protection.

Boiler Reset Procedures

Performing a reset on your Ideal Logic Combi 35 can resolve many minor operational issues. A simple reset involves turning the boiler off at the power switch for approximately 30 seconds‚ then switching it back on. This allows the boiler to restart its internal processes and clear temporary errors. For more persistent faults‚ a factory reset might be necessary‚ typically accessed through the control panel’s advanced settings – consult the full manual for specific button sequences.

However‚ frequent resets indicate an underlying problem requiring professional attention. The ‘LC’ fault code‚ signifying multiple resets within a short timeframe‚ demands immediate investigation by a qualified engineer. Always prioritize safety and avoid attempting complex resets without proper understanding.
