Controls

The controls are located on the top of the heater consisting of a display screen and three buttons and a Dial:

• 1. Display Screen
• 2. 'Menu' Button
• 3. 'Back' Button
• 4. 'Selector Dial'
• 5. 'Enter' Button
• 6. 'Advance' Button
• 7. Heating Status Indicator

Quick Start Guide

The heater is fitted with an adjustable thermostat enabling the room temperature to be controlled. The minimum room temperature is 7°C. The maximum temperature is set to 30°C by default. A temperature of 21°C is a common comfortable room temperature.

The heater controls can be easily adjusted by using the Dial and buttons on the User Interface.

• 1. Home Screen: The main display.
• 2. Menu: Displays the Main Menu, including options for Boost, Modes, and Settings (Time/Date, Temperature units etc.).
• 3. Back: Returns to the previous screen.
• 4. Selector Dial: Rotate to navigate menus and adjust room temperature. Press to enter sub-menus and confirm actions.
• 5. Enter Button: Confirms selections.
• 6. Advance Button: Used in Timer Mode to temporarily change the timer schedule by forcing a 'Heating On' period to begin or end early.

The screen colour changes based on the temperature selected, showing deep blue through to bright red.

Important Notes:

• The outer case of the Quantum heater is cooler to touch than a conventional storage heater, as less heat is lost through the case.
• Nothing may be placed in the 300mm (1 foot) in front of the heater at any time to avoid contact with the grille and heated air, preventing a fire hazard.
• The heater automatically manages heat storage; simply set the timer mode and temperature.
• Ensure both supply switches next to the heater are turned on when heat is required (e.g., in autumn) and can be turned off in summer.

How the Heater Control Works

The control system allows selection of heating on-times and temperature. A low-speed fan discharges stored heat from the core into the room. 'Heating On' periods are when the heater provides heat; 'Heating Off' periods are when it does not. During 'Heating On' periods, the fan maintains the set temperature. During 'Heating Off' periods, the fan is off. There may be a delay of up to a minute for fan operation when switching between modes, which is normal.

Setting the Time and Date

The time and date are factory set but can be checked and adjusted via the Menu > Time/Date option. Rotate the Selector Dial to the correct value and press to confirm. The time automatically adjusts for GMT/BST changes. It is recommended to check the time every couple of months.

Setting the Temperature

The display shows the room temperature setpoint, which the heater maintains during 'Heating On' periods. If the room temperature is higher, the fan will not operate. The factory default is 21°C. Rotate the Selector Dial clockwise or anti-clockwise to adjust the desired temperature.

[Visual: Display showing 21°C]

Note: To change the temperature permanently, modify the room temperature setpoint in your selected timer mode.

Setting the Timer Mode

Your heater comes with four pre-programmed timer modes:

• User Timer: 11 hours heating in 4 periods (06:30-09:30, 11:00-13:00, 15:00-17:00, 18:00-22:00).
• Out All Day: 6.5 hours heating in two periods (07:00-08:30, 17:00-22:00).
• Home All Day: 13 hours of continuous heating (08:00-21:00).
• Away: Set temperature and duration for holidays, reverting to the previous mode upon return.

Note: 'Heating On' times and room temperature setpoints in all modes can be customized.

Which Timer Mode is Best?

The heater defaults to 'User Timer'.

• 'Out All Day' is suitable if you are out during the day and only need heat in mornings and evenings.
• 'Home All Day' is for when you are home during the day.
• 'Away' mode is for extended periods of absence.

Advance Function

The Advance function allows temporary changes to heating schedules. If the heater is in 'Heating Off' mode and heat is desired, press 'Advance'. If in 'Heating On' mode and heat is not desired, press 'Advance'. The heater will then operate until the beginning of the next scheduled 'Heating On' period before returning to the timed schedule.

[Visual: Menu showing 'Advance' option highlighted]

Boost

A supplemental boost element provides additional heating for unusually cold weather. The boost duration can be selected from one to four hours, after which it automatically switches off.

Note: The Boost element uses peak rate electricity and may increase running costs.

Product Clearances

⚠️ WARNING: DO NOT PLACE OBJECTS WITHIN 300mm OF THE FRONT OF THE HEATER, 150mm AT EITHER SIDE OR 250mm FROM THE TOP.

[Diagram: Product clearances showing 300mm clearance at the front, 150mm at each side, and 250mm at the top of the heater. This is a repeat of the diagram in Operating Instructions but relevant here for installation.]

Step 1: Unpacking and Initial Setup

[Diagram: Figure 1 shows the heater flat on the ground with arrows on the carton base pointing upwards. Figure 2 illustrates opening the carton from the bottom, sliding the heater out by at least 200mm to expose the feet and fixing kit. The feet and fixing kit are then removed. Foot screws are located within the fixing kit.]

⚠️ WARNING: The appliance must be securely fixed to the wall. The installed appliance could weigh up to 165kg and if it falls off the wall it could cause severe personal injury or death. It is the responsibility of the installer to ensure that the appropriate wall fixing is used and that the floor is capable of bearing the full weight.

Step 2: Securing the Feet

[Diagram: Figure 3 shows securing the feet to the heater using all provided screws (4 per heater). For models QM050, QM070, and QM100, there are two possible locations marked X and Y on the heater base. Ensure feet are fixed at location holes marked 'X'. If replacing a heater, check the existing foot pitch and choose appropriate positions (X or Y).]

Feet Spacing:

Step 3: Removing Panels

[Diagram: Figure 4 shows removing screws holding the grille panel. Figure 5 illustrates removing screws retaining the heater sides and pushing the sides upwards to release them. Figure 6 shows removing screws securing the front panel and swinging its upper edge upwards to unhook it from the base.]

Note: Retain screws for reassembly. Use M4 X 10 Tritap screws if misplaced.

Step 4: Fixing the Heater to the Wall

[Diagram: Figure 7 shows placing the heater in its final position and marking wall fixing locations visible through the back. The wall fixing bracket is then removed from the heater. Figure 8 shows common fixing points for all heater sizes. The wall bracket is positioned on the marks, holes drilled, and appropriate wall fixings fitted. The heater is then positioned over the bracket and secured with screws at either side.]

Wall Fixing Recommendations:

• Solid Brick/Block: Use No. 10 size high temperature resistant plastic inserts with an 8mm drill bit. Drill 15mm deeper than the insert length.
• Plasterboard: Locate studding and use No. 10 wood screws directly into the wood. Alternatively, use M5 rawlplug inserts.

Note: For other wall types (e.g., timber frame, hollow concrete), seek specialist advice.

⚠️ NOTE: DO NOT FULLY TIGHTEN THE SIDE FIXING SCREWS UNTIL THE ENERGY CELLS ARE FULLY LOADED TO ENSURE FULL WEIGHT IS ON THE FEET AND NOT ON THE WALL FIXINGS.

Step 5: Mains Cable Entry

[Diagram: Figure 9 shows the mains cable entry and terminal block visible in the centre cavity on the right-hand side. Insert mains cables through the cable gland at the bottom of the heater.]

Cable Sizes:

• Peak mains cable: 1.5mm²
• Off-peak mains cable: 2.5mm²
• Single Supply mains cable: 2.5mm²

Only heat-resistant ordinary polyvinyl chloride sheathed flexible cord should be used (IEC: 60227 IEC57 or CENELEC: H05V2V2-F).

Connecting Mains Supplies

⚠️ WARNING: The electrical installation of this heater must be carried out by a suitably qualified or trained electrician, and be in strict accordance with current wiring Regulations.

Supply circuits must incorporate a double pole isolating switch with at least 3mm contact separation.

• Peak supply: Connect via a switched fused spur with a fuse rated suitably for the appliance's flex.
• Off-peak supply: Connect via a 20A double pole switch.

Note: Plug and socket arrangements MUST NOT be used. This heater must be earthed. Do not locate the heater immediately above or below a fixed electrical point (e.g., socket outlet). This appliance is for single-phase supply only, not 3-phase.

Electrical Connections Details

The heater is factory configured for two mains supplies: a 24-hour peak supply and an off-peak switched supply. It can also operate with a single main supply.

WARNING: Terminal block torque: Minimum 2Nm, Maximum 2.2Nm.

Building the Heater Core

Energy Cells: Supplied separately in packs of three (item code 047243). Keep energy cells dry and do not install if moisture has occurred.

[Diagram: Figure 11 shows removing the inner front and insulation to access the heater core. Figure 12 shows removing the cardboard element support.]

[Diagram: Figure 13 explains that energy cells have grooves for locating around elements and central slots for air passages. It details positioning the first energy cell in the bottom row to the right, against side insulation, with grooves facing upwards. The second cell is placed against left-hand insulation, and remaining cells fill the row, ensuring elements are not damaged. Element bends locate in cell grooves for security.]

[Diagram: Figure 14 shows positioning the second row of energy cells upside down on top of the first, ensuring grooves fit over elements. It notes that element tails must extend no further than 30mm into the right-hand chamber.]

[Diagram: Figure 15 shows the third row of energy cells positioned similarly to the first row. Figure 16 shows the fourth row fitted upside down above the third. This process is repeated for fifth and sixth rows around the third element to complete the core build.]

[Diagram: Figure 17 shows that the top row of energy cells must be fitted upside down. Figure 18 shows refitting the inner front panel complete with insulation, ensuring bottom tabs are located inside the chassis and screws are secured down each edge.]

IMPORTANT: After energy cells are fully loaded, ensure screws retaining the heater to the wall are fully tightened (refer to Fig. 8, page 7). Double-check all mains connections are secure and excess cable is restrained and not in contact with the heater casing.

Reassembly

To replace the front panel, bottom grille, and side panels, reverse steps from Figures 4, 5, and 6 (page 6). Ensure all fixings are secure.

IMPORTANT: Once installed, DO NOT attempt to reposition the heater without first unloading the energy cells.
