This document is a user guide for the Ideal Logic Combi, Logic Combi E, and Logic + Combi electronic 7-day timers, specifically for models 24, 30, and 35. It provides instructions for setting up and using the timer, as well as advanced features and troubleshooting information for boiler error codes.

Function Description:

The Ideal Logic Combi Timer is an electronic 7-day timer designed to control the central heating system of Ideal Logic Combi, Logic Combi E, and Logic + Combi boilers. It allows users to program specific "on" and "off" times for central heating over a 7-day period, providing flexible and energy-efficient control. The timer automatically updates for Summer/Winter Time (GMT/BST) changes. It features a simple user interface and provides English language boiler fault messages with suggested corrective actions to aid diagnostics.

Important Technical Specifications:

The timer includes a Real Time Clock (RTC) with a backup supply to maintain the date and time even when power is removed from the boiler. If power is removed for more than 3 hours and then restored, the date and time will need to be re-entered, but programmed periods will be retained.
