The Newera Profile panel heater range is designed for wall mounting on the wall brackets supplied. It  
should only be operated when in the upright position as shown in diagram C.  
All models are protected against moisture ingress to IPX4 standard.  
All models, except those with no controls, are fitted with a 7-day digital programmer.  
Installation:  
Before connecting the heater, check that the supply voltage is the same as that stated on the rating label.  
When selecting the position for the heater to be installed, consideration should be given to ensure that there  
are no obstructions closer than the dimensions given in Diagram C. The bracket for the heater should be  
fitted in accordance with the method detailed in the associated diagrams. The heater must not be located  
below a socket outlet or connection box.  
Care must be exercised when fitting the heater onto the bracket. Pressure should only be applied to  
the ends of the heater and not to the grille area.  
The electrical installation must be carried out by a competent electrician and in accordance with the current  
Electrical Wiring Regulations (BS7671) and/or local regulations.  
The heater is fitted with a length of flexible cable for connection to the fixed wiring of the premises via a  
suitable connection box positioned adjacent to the heater.  
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly  
qualified persons in order to avoid a hazard.  
A means for disconnection in all poles must be incorporated in the fixed wiring in accordance with  
the wiring rules.  
WARNING – THIS APPLIANCE MUST BE EARTHED  
WARNING – In order to avoid overheating, do not cover the heater.

No Controls Models – 75-772901, 75-772902, 75-772903, 75-772904 and 75-772905  
These models can be installed in association with a separate room thermostat control.  
Bracket release for cleaning  
For safety, the heater should be switched off at the mains before proceeding. To release  
the panel heater from the bracket, the rear catch must be pressed down while pulling the  
heater forward gently. It is recommended to use a narrow tool for this purpose. A pencil  
or small screwdriver would be a suitable tool. Diagram D shows the procedure for  
releasing the heater from the bracket.  
When replacing the heater on the bracket, firstly engage the heater on to the bottom hooks  
and then press the heater on to the catch. It is recommended to press the heater at the  
ends and not to the grille area.  
The Panel - How it works  
A heating element within the metal case warms its front face for direct radiation into the room and a gentle circulation of  
warm air around the room. The built-in thermostat with its adjustment knob located behind the controls door, controls  
the room temperature by sensing this from the air passing upwards through the panel. The knob selection provides  
settings from 1 to 6 and each increase in number equates to approximately 7°C temperature difference. Position 1  
represents 7°C and would be used for frost protection when the property is not occupied. Position 3 represents 21°C  
and is the normal comfort position.  
NOTE – Should your heater fail to come on when the thermostat knob is at a low setting, this may be due to the  
temperature of the room being higher than the thermostat setting.  
Timer/Programmer  
A digital timer/programmer is built into the product and is situated behind the controls door. This will control the  
operation of the heater for the time periods set at the thermostat setting.  
Setting up  
If, at any time during setting, a period of approximately 7 seconds passes with no button pressed then the timer reverts  
to the clock display and saves the settings thus far.  
To set the clock,  
firstly press the left button below where it says “SETUP” on the display. Five options will be  
displayed on the right side of the display. These are PROG, DOWN, CLOCK, SUMMER and RANDOM. PROG will be  
flashing at this time. Press the “+” button twice to move the flashing to “CLOCK”, and then press the left button to  
“AFFIRM” the choice. The hour display will now be flashing and pressing the + or – buttons will set the display to the  
required setting. Then press the AFFIRM button and the minutes display will be flashing and again the + and – buttons  
will set the display to the required setting. Press the AFFIRM button and the day display will be flashing and the + and –  
button will set the day to the required setting. Press the AFFIRM button to end the clock setting and return to the clock  
display.  
To set the Program,  
firstly press the left button below where it says “SETUP” on the display. Five options will be  
displayed on the right side of the display. These are PROG, DOWN, CLOCK, SUMMER and RANDOM. PROG will be  
flashing at this time. Press the AFFIRM button and the 01ON display will be flashing. Press the AFFIRM button and the  
hour display will flash and be adjustable by the + and – buttons. Pressing AFFIRM will move the display to the minutes,  
and then to the days. The days have special groupings that can be selected by pressing the + and - buttons. They are  
MO TU WE TH FR , SA SU , MO TU WE TH FR SA , MO WE FR , TU TH SA , MO TU WE , TH FR SA ,  
ALL DAYS and individual days. Make your selection and press AFFIRM. The 01ON display will flash. Pressing the +  
button will advance the display to 01OFF and the same procedure should be followed for setting the OFF time  
remembering to use the same day selection. The procedure should be followed through to complete your programming  
requirements up to maximum step 12OFF. Any unwanted steps may be left blank.  
Manual Over-ride  
The timer can be over-ridden at any time by pressing the right-hand button until the display  
shows the required mode ALWAYS ON or ALWAYS OFF. The timer must be returned to the PROG position for the  
timer and its programs to be active.  
Summer Setting  
For setting the clock forward 1 hour for summer, press SETUP and select Summer on the  
display then press +. To unset the summer setting, repeat the procedure.  
Down Timer  
The heater can be set to be ON for a fixed time by selecting DOWN from the SETUP screen  
and using the + and buttons to set the required hours. Then press AFFIRM and set the minutes followed by AFFIRM.  
The heater will then operate until the time expires.
