without any change.
Automatic mode: System will control temperature
according to the preset temperature values in dierent
time settings. The Auto symbol will show, which means
the system is running under Automatic mode.
In the Automatic mode, the main display area will alternately
display the day of the week (WEEK) and the daily schedule

FLOOR icon will appear in the lower sub-display.
Schedule Settings
Press Menu for 5 seconds to enter the schedule settings
mode. The display will show the featured week e.g. 5 + 2 / 6
+ 1 or 7 days. Each period can be set for the desired time and

P1. Press Menu to move onto the settings for P2. Repeat this
procedure through P1 to P6. You can press the Clock icon to
go back to previous settings. Finally, press ON/OFF twice
to confirm.
If you want to turn o a period, then in the temperature
setting for the period press DOWN until OFF is displayed in

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.
Three types of Temperature Control
and Display
The thermostat can be set to operate in three dierent 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
measurement & suitable for oor temperature control only.
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 oor temperature
monitoring. If the external sensor is over temperature, the
thermostat will shut down the heater.
When the setting is IN or ALL the main display shows air or
room temperature. When the thermostat is set in OUT mode,
the oor icon will be lit and the main screen will display oor
temperature.

PROBLEMS AND SOLUTIONS
There is no display
a) Check power supply to thermostat.
b) Check the thermostat is wired as the wiring diagram on the
back side of the thermostat.
Display ruptured
a) Display has been subjected to abuse with hard objects or
sudden force.
Display a black screen
a) If the display surface temperature is too high. Please note
whether there is a heater nearby and if so, remove.
Displays ER0 or ER1
a) ER0: 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) ER1: 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
Check whether the steel plate has been deformed during
installation. If deformed, correct it.
Large deviation of measured temperature and the
actual temperature
a) The 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.
INSTALLATION
A: Hook B: Central xing lug
1. Remove the bezel to start the installation by pushing the
bezel away from the main body of the thermostat
2. Pull outwards on the central xing 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
3. Screw the steel back plate into the back box but not too
tight to prevent deformation of the steel plate
4. Make the wire connections into the back of the
thermostat as shown in the H3 wire diagram
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
