INSTALLATION INSTRUCTIONS
ELECTRICAL CONNECTION
A qualied electrician must carry out the electrical installation of this radiator. The electrical installation must comply with
the current UK and Irish regulations. Any claim on the warranty could be invalid if these requirements have not been met.
The radiator requires a 230/240V 50/60Hz power supply.
Connecting wires:
Brown: Live
Blue: Neutral
Yellow-Green: Earth
The connecting wires must be of the appropriate section, in regards to the length of cable, type of cable and power rating
of the apparatus.
The apparatus must be connected into a fused connecting box tted with an appropriate sized fuse for the radiator – see
Technical Data on Page 4.
We recommend that the connecting box is positioned 10cm to the right of the apparatus and at 15cm above the oor.
According to regulations, the apparatus must be connected to the power supply by means of an all-pole circuit breaker
with a contact gap of at least 3mm or by a thermal-magnetic circuit breaker.
LOCATION
The ideal place to position the Sun Ray RF radiator is as close as possible to coolest wall in the room but it is not
recommended to site the radiator on un-insulated exterior walls, in this case, the part of the wall behind the radiator
should be insulated.
In bathrooms, the radiators must not be installed inside the protected areas. In the UK the heater must be mounted
outside Zone 2. In Ireland the heater must be mounted outside Zone 3. The control unit switches must not be reachable,
directly or indirectly, by a person in the bath / shower or using the wash basin.
The radiator, under no circumstances, should be installed below an electric power point.
Choose the location of the radiator in respect of the minimum distances that are indicated in Figure A.
Note: If the window sill protrudes less than 20mm the gap above the heater can be disregarded.

MOUNTING THE RADIATOR
Place the radiator on the oor, as shown in Figure 1. For radiators with 4, 6, 8 or 10 elements position the supports
supplied with the radiator as shown in Figure 1. For radiators with 12 elements the supports should be positioned
between the second and third elements from each end.
Fig. 1
Fig. 2a
Fig. 3a
Fig. 2b
Fig. 3b
Place the supports between the elements as shown in Figure 2a, mark points on the walls through the xing holes as
shown in Figure 2b. This determines the spacing of the supports. Fix the supports to the wall with plugs and screws. Be
sure that the supports are mounted in the correct position.
Lift the radiator and hang it on the supports, as shown in Figures 3a and 3b.

Fig. 4 Fig. 5
UNLOCKED LOCKED
Once the heater is hanging as shown in gure 3b, attach locking bracket shown in gure 4 to the bottom right hand side
of the heater using screw 1.
Mark the location of screw 2 on the wall and then remove the bracket. Drill the hole for the xing and insert the supplied
wall plug, re-attach the locking bracket to the heater and then x the heater to the wall with screw 2, then push on the
left side of the locking plates on the top brackets until a click is heard. See Figure 5.
CONTROL OPTIONS
The Sun Ray RF is designed to be used in conjunction with the SunRay Smart Gateway system and App, providing
total control of your radiators from anywhere in the world via the internet. The App is available for both Android and IOS
devices and offers the ultimate in control and energy monitoring.
Search for “Tevolve” on the either the Google Play store or the Apple App Store.
It is also possible to programme each radiator individually without the App by using the inbuilt buttons and LCD screen.
This may be convenient for single radiators however we recommend the Sun Ray RF Gateway to control multiple
radiators.
Finally the radiators can be used in manual mode or Easy mode which bypasses any programming and provides simple
On/Off operation.

If the radiator has been linked to the Gateway
and for some reason communication is lost, the
Link icon disappears and the antenna starts
ashing in red alternating with Link text.
KEYPAD LOCKING (ANTI-TAMPER)
The keypad can be locked
to prevent any unauthorised
person (children, people in public
places, nurseries, ofces, hotels
etc.) altering the settings of the
radiator.
A Password is required to lock
the keypad (0 0 0 0 by default),
See Password Settings Chapter
for further details on changing
passwords.
To Lock the radiator Press and
hold the + and – buttons until
the lock screen appears. Enter
the password on the screen and
press Ok. The screen will change
to show the Lock screen and any
button presses will be ignored
and the locked screen displayed.
To unlock the keypad press
and hold the + and - until the
unlock screen appears. Enter the
password and press OK. If the incorrect password
is entered “INVALID CODE” will be displayed.
When the keypad is locked the radiator will
still receive communications from the Sun Ray RF
Gateway.
ADVANCED SETTINGS
The Advanced settings menu
is password protected to prevent
any inadvertent changes to the
factory settings.
To access the Advanced
settings, enter the password
(default 0 0 0 0). It is
recommended to set a custom
password once installation is complete. (For more
information See password section).
The units menu allows the
main temperature units of the
radiator to be chosen between
Celsius (°C) and Fahrenheit (°F).
The Control Type menu
allows two types of control of
the temperature control setting.
PID will calculate the best
switching point for the heater
depending on previous room
readings. Hysteresis is the
amount of difference between
the detected temperature and the setpoint. It is
not recommended to change these settings.
The temperature offset menu
allows the display temp to be
adjusted by ± 3. Adjusting this
setpoint will affect the operation
of the thermostat setpoints,
changing this setting is only
recommended if the displayed
temperature is noticeably
different from another sensor in the space.

and the heating will come on prior
to the programmed starting time
so that the room is at the correct
temperature at the programmed
starting time.
The Low Surface Temperature
(LST) menu will allow the output
of the heater to be limited to a
lower setting to prevent the
surface of the heater becoming
too hot. If a surface temperature
of less than 43°C is required use
the lowest setting.
It is recommended that if the
LST function is activated then
the radiator should be locked
with a non standard password
after activation.
(See Password Section)
EASY Mode is a simple mode
of operation where by only the
+ and – buttons on the radiator
operate to increase or decrease
the temperature. The OK button
is deactivated. To turn the

RUNBACK MODE
The Sunray RF Heater comes with a runback
mode for use when the heater will be installed in
areas where restricted user control is required.
When Runback Mode is active it allows the user
to set the radiator to run for a specic pre-set
amount of time and temperature. It is also possible
to set a maximum temperature (Max Temp) above
the Runback setting to allow the user to increase
the temperature within the limits allowed.
Before activating Runback mode it is strongly
recommended that an alternative password is set
and activated and the comfort mode temperature
setpoint is set to 35°C. When the password is
activated the user will have no access to the
radiator settings without the password.
NOTE: Any Display settings will be used in
RUNBACK mode, eg. Backlight time and intensity,
Eco mode etc.
After the runback time period ends the room
temperature will return to off (7°C minimum) until
the runback is restarted.
It is also possible to set a minimum temperature
to be maintained (Setback) outside of the runback
mode; when setback mode is activated the room
temperature will only fall as low as the Setback
temp and be maintained at this point until runback
is restarted.
ACTIVATING RUNBACK MODE
Runback mode is activated
from the Advanced settings
menu.
The main runback screen has
3 options:
• Runback Cong
• Setback Cong
• Max Temp
Set Runback to ON to activate
the mode.

The Default time for Runback
to operate is 30 minutes, this can
be increased in ½ hour sections
up to 8 hours (480 mins) by using
the + & - and OK.
0 → 30 → 60 → 90 → 120 →

420 → 450 → 480 →0
The time can be limited to any of the above
values, when the user activates the Runback
timer, they can choose any of the times up to the
maximum set on installation.
The temperature that the
radiator runs at when runback is
activated is set in the Runback
Temp menu. Use + & - to Set the
temperature and Press OK.
Please note that the Runback
temperature cannot be set
higher than the Comfort setting
in the main menu.
SETBACK
The setback mode can be
used to limit the temperature
that the area where the heater
is installed can fall to outside
of the Runback operation. This
temperature can be set between
7°C and 0.5°C less than the
Runback temperature.
When Setback
is operational,
the screen will
show setback
and the setpoint.
MAX TEMPERATURE
The Max Temperature mode
allows the installer to set a
temperature higher than the
Runback temperature to give
the user some leeway in the
temperature of the room.
Typically this is set 1-2°C higher
than the runback setting.
Both the Setback and Max
temp are set with the +&- buttons
from their respective menus.
The graphs below show typical scenarios for
each of the settings.
When Setback and Max temp is OFF, the user
has a choice between the minimum radiator
temperature of 7°C and the Runback temp setting.
Outside of the Runback period the temperature
will fall as low as 7°C if the radiator is not re-
activated.
When Runback and Setback are activated then
the user has a limited choice of temperature
between the Setback setting and the Runback
setting.
Outside of the Runback period the temperature
will fall to the Setback temperature if the radiator
is not re-activated. (Building Fabric Protection)

TROUBLESHOOTING
If the power of the Lithium
battery drops, the screen shows
the low battery icon in startup
screen for 5 sec. and returns to
normal mode.
In every active screen a small
icon will remind the user that
the battery is at. The time and
date is not retained if the radiator
main switch is disconnected.
If the radiator is paired with
an internet connected gateway
the time and date are always
updated when the radiator
reconnects to the gateway.
When a radiator has been
paired with a Gateway, the text
“Link” and an antenna with
ashing waves appears on the
top right of the screen.
When the Gateway is not
powered or it is too far away from
radiator, the Link text alternates
with a red antenna without
waves to alert the user that the
radiator cannot comunicate with
the gateway.
If radiator is paired with a gateway, and the
internet connection is lost the heating system is
not accessible from the app. However the running
schedule remains in the radiator memory and
continues with the last user setting if the lithium
battery is not at.
(Lithium battery CR2032 life is around 5 years
from date of manufacture, this life can be
decreased depending storage conditions)

MAINTENANCE AND CARE
Sun Ray RF radiators require very little maintenance.
The surfaces of the radiator must not be cleaned with an abrasive product or those containing granular substances.
We recommend regular cleaning with PH neutral products.
In order to clean the radiator, it is recommended that the electric power is switched off. Failure to keep the SunRay
Radiators clean may result in dust becoming burnt and depositing on the wall above the heater in the form of dark
streaks or patches. This type of marking is expressly due to failure to keep the heater and surrounding area clean. ATC
take no responsability for any such damage caused
