This guide is for quick reference only. Please refer to the operating section for further information.
• In order to avoid overheating, Do Not Cover the heater. Do not place matrerial or garments on the heater, or obstruct
the air circulation around the heater.
• Ensure that both supply swtiches next to the heater are turned on. During the summer when no heat is required, both
wall switches can be turned o. Remember to turn both of these back on in Autumn when heat is required.
• CAUTION as some parts of this product can become very hot and cause burns. Particular attention has to be given where
children and vulnerable people are present.
• Note that due care and consideration must be taken when using this heater in series with thermal control, a program
controller, a timer or any other device that switches on the heat automatically, since a re risk exists when the heater is
accidentally covered or displaced.
How Does the Heater Control Work?
The control allows you to choose when you want heat and at what temperature.
When using a timer mode (see below), Comfort On will display on the home screen to tell you when the heater is maintaining
the temperature displayed. Comfort Off will display when the heater is outside of a timed heating period.
When Manual, Eco or Frost modes are being used the heater will always maintain the temperature shown on the home
screen.
Set the Time
To set the date and time on the heater, press Menu, then press the Enter with Time / Date highlighted. Press or until
the correct value is shown, then press Enter to conrm and move on to the next value. Repeat until all details are correct,
and Set displays, then press Back.
The time is automatically adjusted in spring and autumn between Greenwich Mean Time (GMT) and British Summer Time
(BST).
Set the Temperature
The temperature shown on the display is the room temperature set point. This is the temperature that the
heater will maintain during heating periods. If the room temperature is above this temperature then the
heater will not operate. The heater leaves the factory with this temperature set at 21°C which represents a
typical, comfortable room temperature. If you require a dierent room temperature then press either or
on the home screen until the display shows the temperature you require.
Timer Modes
Your Quantum heater comes pre-programmed with four timer
modes. These modes dene the periods when the heater will
operate in Comfort On mode. The four modes are:
Timer Mode Description
Out All Day 6 hours heating per day in two periods
Home All Day 9 hours heating per day in one period
Holiday
User Timer Customise times in four periods
Set the number of days for which you are
on holiday
Which Timer Mode is Best for Me?
The heater leaves the factory set in Out All Day mode. If you are out during the day and only require heat in the
mornings and evenings then this mode will suit your lifestyle and you won’t need to alter anything. If you are in
during the day then you should select the Home All Day mode which is a single heating period. The times of these
modes can be modied, or the User Timer mode can be used to give you four periods of heating split throughout
the day. If you are away for an extended period then you can use the Holiday mode. This allows you to reduce the
heating during the period that you are away, reverting to the previously selected mode on the day you return.
To choose a timer mode press Menu followed by Enter to select Mode then Timer Mode. Select the mode
required by pressing or then Enter. For options Out All Day, Home All Day and User Timer, three
choices are available - Select, Preview and Modify.
Select - Choose this timer option
Preview - View the times currently set
Modify - Change the times currently set
(Please refer to the operating section of this manual for information on how to modify the programmed times.)
