USER GUIDE

Welcome to your new Ideal Halo Lite. This thermostat will help you to control both your heating temperature and the times that your heating is on.

You can choose to run your heating in “Auto” mode where you can set daily schedules for your heating to come on at specific times; this can be useful if you have a regular daily routine and want your heating on at the same time each day.

Alternatively, you could choose to run your heating in “Manual” mode, this means there are no schedules set and you can simply turn the temperature of your heating up and down manually using the dial.

USING YOUR HALO LITE

TOP TIP
Your Halo Lite is designed to provide the perfect balance of comfort and efficiency. It has a feature called Enhanced Load Compensation which balances the temperature in your radiators to maintain the target room temperature with optimum efficiency. As a result you might notice that when the temperature in your home reaches the target your radiators are not hot to touch. By controlling the temperature in your radiators your system is working in the most efficient way for you.

OVERRIDE
If you are running a schedule with pre-set times (Auto mode) and you want to adjust the temperature of your heating temporarily, simply turn the dial to your desired temperature. A pop up menu will appear for you to select how long you would like to change the temperature for, turn and push the dial to make your selection.
TOP TIP

Turn the dial to select how long you would like the target temperature altered for. You can select either until the next change in heating temperature is scheduled or a number of hours.

PLUS HOURS
If you are running a schedule with pre-set times (Auto mode) and you want to maintain the current temperature of your heating instead of moving to the next setting simply press the dial. A pop up menu will appear for you to select how long you would like to extend the temperature for, turn and push the dial to make your selection.
