Wiring details: These are printed on the back of the
thermostat casing.
The floor sensor is connected to terminals T1 & T2 (please
note there is no polarity and the twin core sensor cable can
be connected either way). The 230V electrical supply connects
to terminals L (Live) & N (Neutral). The heating mat(s) connect
to terminals L1 (Live) & N1 ( Neutral). Earth connections are
made with the back box. When the thermostat is powered
for the first time you may see “OFF” on the screen in the lower
sub-display.
Press ON / OFF symbol to activate and turn on your
thermostat.
Keypad Lock - Press Clock symbol and Menu at the same
time for 2 seconds.
Repeat to unlock. LCD display will show the temperature value
when keypad is locked.
Press the power ON/OFF key to turn the thermostat ON
or OFF. The display will be as below when turning OFF.
Three types of Temperature Control
and Display
The thermostat can be set to operate in three different modes;
IN: Internal, OUT: External, ALL: combined internal and
external. The default setting is IN. Enter the advance functions
to change the mode setting.
Internal control (IN): Based on built-in sensor temperature
measurement & suitable for detection of air or room
temperature only.
External control (OUT): Based on external temperature
Press Menu to choose between Manual
Mode and Automatic Mode.
measurement & suitable for floor temperature control only.
ADVANCED FUNCTION SETTINGS
Dual temperature control (ALL): Temperature control
based on built-in internal temperature sensor and external
temperature sensor (over temperature protection). Suitable
for detection of room temperature and floor temperature
monitoring. If the external sensor is over temperature, the
thermostat will shut down the heater.
Press ON/OFF until the sub-display shows OFF,
press ON/OFF again, then immediately press Menu.
You are now in the Advanced Function Settings. The first
display will be Adj. Press Menu to navigate through the
menu items. Use UP or DOWN to change the settings.
When the setting is IN or ALL the main display shows air or
room temperature. When the thermostat is set in OUT mode,
the floor icon will be lit and the main screen will display floor
temperature.
WARNING: The settings are used to set some important
parameters of the system and the thermostat has already
been debugged and tested by professionals, there is no
need to reset.
Do not make any improper modifications and permit
changes only by a qualified person.
To save the data go through the functions then exit at any
time by pressing the menu key.
In the Automatic mode, the main display area will alternately
display the day of the week (WEEK) and the daily schedule
stage (STAGE).
Manual mode: The schedule programme is overridden
and the temperature can be adjusted to your individual
requirements. The system will control at this temperature
without any change.
Automatic mode: System will control temperature
according to the preset temperature values in different
time settings. The Auto symbol will show, which means
the system is running under Automatic mode.
Setting the time and day of the week
In the sub-display it will show the set temperature and time
alternately.
Press UP & DOWN arrows to adjust temperature settings and
other settings.

go back to previous settings. Finally, press ON/OFF twice
to confirm.
Press Menu for 5 seconds to enter the schedule settings
mode. The display will show the featured week e.g. 5 + 2 / 6

To quickly return to the original display press ON/OFF twice.
The system default is 5 + 2 and the default settings are as the
following table. For example, when the system time is Friday
08:20 under Automatic mode the display would show as

Temperature Override Facility –
Manual Mode Only
This allows you to override the temperature setting at any
time. For example, you arrive home early and want the
heat on. Press Menu to enter Manual mode. Assume the set
point in the schedule was 15ºC and the room temperature is
actually 18ºC. The heating will not be energised in this setting.
Press UP or DOWN to adjust the temperature above 18ºC. Let’s
say 22ºC, and the heating symbol will appear and the heating
is now ON.
INSTALLATION
A: Hook
B: Central fixing lug
1.Remove the bezel to start the installation by pushing the
bezel away from the main body of the thermostat
4.Make the wire connections into the back of the
thermostat as shown in the H3 wire diagram
2.Pull outwards on the central fixing lug and at the same
time lift the whole body assembly so that the hooks on
the steel back plate can be released. The steel back plate
can then be removed
5.Align the four hooks and with a press down movement
click the main body of the thermostat back in position on
the steel back plate
6. Replace the bezel and the installation is complete
3.Screw the steel back plate into the back box but not too
tight to prevent deformation of the steel plate

PROBLEMS and SOLUTIONS
There is no display
a) Check power supply to thermostat.
b) C
heck the thermostat is wired as the wiring diagram on the
back side of the thermostat.
Display ruptured
Displays ER0 or ER1
a) E R0: Built-in sensor is damaged. Avoid damage to the
small black dot sensor which can be found behind the
temperature sensing window of the main thermostat
panel.
b) E R1: The system is set in dual Temperature Control mode
(ALL) and the external sensor is not connected or is
damaged.
Missing segments from numbers or letters on LCD
a) D
isplay has been subjected to abuse with hard objects or
sudden force.
Check whether the steel plate has been deformed during
installation. If deformed, correct it.
Display a black screen
Large deviation of measured temperature and the
actual temperature
a) I f the display surface temperature is too high. Please note
whether there is a heater nearby and if so, remove.
a) T he thermostat should be installed in a ventilated room
and never in direct contact with sunlight or localised
heaters.
b) Check terminal connections, including the sensor.
