User Guide for Ideal Halo 2-Zone Upgrade Kit

Quick Guide from the Manual

The Ideal Halo 2-Zone Upgrade Kit is a wireless heating control system designed to manage central heating zones independently. It consists of a battery-powered thermostat, a Smart Interface (installed in the boiler), and a Smart Wiring Centre. The system supports Auto, Manual, and Off modes, allowing for flexible temperature control and energy efficiency.

Understanding the Display

The Halo display provides real-time information about your heating system:

• Flame Symbol: Indicates heating is currently on.
• Target Temperature: The desired temperature you have set.
• Current Temperature: The actual room temperature.
• Mode Indicator: Shows whether the system is in Auto, Manual, or Off mode.
• Override Icon: Appears when a temporary temperature adjustment is active.

Operating Modes

You can switch between modes using the right-hand button and the dial:

• Auto: Runs heating according to pre-set scheduled times and temperatures.
• Manual: Allows you to control the temperature manually by turning the dial.
• Off: Sets the heating to a low temperature (default 5°C) for frost protection.

Scheduling

The Halo allows you to program up to 6 heating events per day. You can customize schedules for different days of the week to suit your lifestyle. To edit a schedule, navigate to the 'timed heating schedule' section in the main menu. You can also use the 'copy day' feature to apply schedules to multiple days.

Override and Plus Hours

If you need to temporarily adjust your heating:

• Override: Turn the dial to adjust the temperature. This will remain active until the next scheduled change.
• Plus Hours: Press the dial while in Auto mode to extend the current heating setting for a specific duration.

Halo Smart Interface and Wiring Centre

These components communicate wirelessly with your Halo control. Under normal circumstances, you do not need to interact with them. However, they feature LED indicators that help diagnose technical issues. Both units include a Failsafe/Override feature to manually operate the boiler or zone valves if wireless communication is lost.

Maintenance and Battery Replacement

When the battery symbol on the display turns red, the batteries need to be replaced:

1. Gently pull the Halo unit away from the rear housing using the finger grabs (do not use a screwdriver).
2. Remove the old batteries and insert 4 new AA Alkaline batteries, ensuring correct orientation.
3. Push the unit back onto the rear housing until you feel a click.
4. The system will perform a short synchronization process.

Troubleshooting

If you encounter issues such as 'CF01 Fault' (Halo not communicating with Smart Interface) or 'CF02 Fault' (Smart Wiring Centre not communicating), check the following:

• Ensure the batteries in the Halo are fresh.
• Check the power indicator on the Smart Interface.
• Verify the distance between the Halo, Smart Interface, and Smart Wiring Centre.
• If you use a Zigbee booster, ensure it is powered on.
