Introducing the Logic Max System

The impressive Logic Max is a system boiler, which means it works with a separate hot water cylinder in your home to provide central heating and hot water. Easy to install and service, this dependable model features an Ideal System Filter which improves its efficiency by removing impurities from the water that passes through it. 

The Logic Max System is a hard-wearing and compact model that can be safely stored in a boiler cupboard. It is available in outputs of 15kW, 18kW, 24kW and 30kW, and has been designed to be easy to install and service.

Operating Your Logic Max System Boiler Efficiently

The modern and efficient Logic Max System can change its output depending on whether you need it to provide more or less heat for your home. In warmer seasons it will use less energy, meaning you will be able to save money on your energy bills.

To help your boiler operate more efficiently when the weather is better, move the central heating temperature knob (A) to the ‘e‘ position or lower. When you need your boiler to provide more heat during winter, simply turn the knob towards the ‘MAX’ setting. 

Low Water Pressure

A quick look at the pressure gauge on your boiler controls (G) will reveal the pressure of your central heating system. If you find that the pressure has fallen below the original installation pressure of 1-2 bar, you’ll find instructions for re-pressurising your boiler on page 4 of the full Logic Max System user guide. 

If you have trouble with these instructions or find that the pressure is continuing to drop, we recommend getting in touch with a Gas Safe-registered engineer.

Weather Compensation

When fitted with a Weather Compensation option, the Logic Max System’s Central Heating Temperature Control knob (A) can be used to control room temperature. Turn the knob clockwise to increase the room temperature, or turn it counterclockwise to make the room temperature cooler. 

When you find a room temperature you’re happy with, keep the knob in this position. The room temperature will automatically be kept at the same level, no matter whether it is warm or cool outside.
