• Temperature below 10°C is displayed without
the preceding "0".
• Temperature exceeding measurement range will
be indicated by "HI" for temperature exceeds
upper limit and "LO" for temperature exceeds
lower limit.
• Temperature sampling is performed every 15
seconds and is only in Normal mode.
• Battery status is sampled every minute in
Normal mode.
• Temperature and battery sampling will not be
performed when there has been any key
pressed in the last 10 seconds.
• Key debounce is implemented on both key
depress and release with duration longer than

Reviewing Setpoint Temperature:
•Press or to review the Setpoint temperature.
•Press BL/FROST or wait
3 seconds without key
press to return to normal
operation, room
temperature will be
displayed.
• Setpoint Temperature will stop flashing when a
key is pressed, then flashes again once the key is
released.

seconds if no key is pressed.
When Frost Protection is enabled, setting of
Setpoint temperature is prohibited.
Frost Protection:
•Press and hold BL/FROST for 3 seconds to
activate Frost Protection.
The Setpoint temperature is automatically set to 5°C
to prevent frosting.
Whenever the Frost Protection is activated, the Frost
Protection indicator is animating with the below
sequence in 4Hz
•Press BL/FROST for 3 seconds to de-activate the

Setpoint Temperature setting.
Low-Battery Detection:
Battery voltage is sampled every minute. When the
battery voltage drops to a certain level, the Low-
Battery warning indicator appears.
• The thermostat functions normally during
battery low. However, user must change the
batteries as soon as possible before they are
so weak that normal operation cannot be
assured.
• Battery voltage is determined as "low" when it is
less than or equal to 2.6V. It is determined as
normal when it is higher than or equal to 2.8V,
i.e.Low-Battery indicator must come out when
battery voltage is <= 2.6V, and must be turn off
when battery voltage is >= 2.8V.
• Battery voltage is only sampled in Normal mode
and when LCD backlight is turned off.
Sleep Mode:
•Press and hold and for 3 seconds
simultaneously to enter the Sleep mode.
•All the functions will be paused to save battery

PRIOR TO INSTALLING PLEASE
READ THE INSTALLATION GUIDE
The RT 300 is easily installed using the Industry
Standard back plate supplied which can be
mounted directly to the wall surface or a single
gang recessed box using the holes provided; cable
entry is from the rear.
The RT300 must be located where it would not be
subjected to extraneous heat gain/loss (such as
above radiators, direct sunlight or in draughts).
Normal household air circulation.

User Instructions
Initial Power Up:
• After power up or RESET is pressed, the
thermostat is reset.
• During system reset, all LCD segments are
turned on for 2 seconds.
After 2 seconds the thermostat is initialised.
The typical reset display is shown below.
5 6 7 8 9 10
Others:
•All flashing indications are 1Hz (0.5 second on,
0.5 second off).
• Temperature below 10°C is displayed without
the preceding "0".
• Temperature exceeding measurement range will
be indicated by "HI" for temperature exceeds
upper limit and "LO" for temperature exceeds
lower limit.
• Temperature sampling is performed every 15
seconds and is only in Normal mode.
• Battery status is sampled every minute in
Normal mode.
• Temperature and battery sampling will not be
performed when there has been any key
pressed in the last 10 seconds.
• Key debounce is implemented on both key
depress and release with duration longer than
20ms.
• Following table is the setting of the thermostat
after reset.
Function Status after Reset
Operation Mode Normal mode
Room Temperature 22.0°C, to be renewed
within 5 seconds
Setpoint Temperature 20.0°C
°C indicator On
Frost Protection indicator Off
Heat indicator Off
Low-Battery Warning Off, to be renewed
indicator within 5 seconds
Output Relay Off
After reset, the thermostat is operating at Normal
mode. Setpoint temperature is reset to default setting.
Room temperature is updated in 5 seconds and the
control process starts.
Reviewing Setpoint Temperature:
• Press or to review the Setpoint temperature.
• Press BL/FROST or wait
3 seconds without key
press to return to normal
operation, room
temperature will be
displayed.
• Setpoint Temperature will stop flashing when a
key is pressed, then flashes again once the key is
released.
• Thermostat will return to normal mode after 3-4
seconds if no key is pressed.
When Frost Protection is enabled, setting of
Setpoint temperature is prohibited.
Frost Protection:
• Press and hold BL/FROST for 3 seconds to
activate Frost Protection.
The Setpoint temperature is automatically set to 5°C
to prevent frosting.
Whenever the Frost Protection is activated, the Frost
Protection indicator is animating with the below
sequence in 4Hz
• Press BL/FROST for 3 seconds to de-activate the
Frost Protection, the Frost Protection indicator is
turned off.
LCD Backlight:
•LCD backlight is activated when BL/FROST or
any key is pressed. The backlight will
automatically turn off 5 seconds after all keys are
released.
•LCD backlight will not operate when battery is
low.
•LCD backlight isilluminated throughout the
Setpoint Temperature setting.
Low-Battery Detection:
Battery voltage is sampled every minute. When the
battery voltage drops to a certain level, the Low-
Battery warning indicator appears.
• The thermostat functions normally during
battery low. However, user must change the
batteries as soon as possible before they are
so weak that normal operation cannot be
assured.
• Battery voltage is determined as "low" when it is
less than or equal to 2.6V. It is determined as
normal when it is higher than or equal to 2.8V,
i.e.Low-Battery indicator must come out when
battery voltage is <= 2.6V, and must be turn off
when battery voltage is >= 2.8V.
• Battery voltage is only sampled in Normal mode
and when LCD backlight is turned off.
Sleep Mode:
•Press and hold and for 3 seconds
simultaneously to enter the Sleep mode.
•All the functions will be paused to save battery
power.
•The whole LCD will be blank.
• Output will be turned off immediately.
•Press any key to wake up the unit.

noting the advice in page
1 of this manual, a suitable
mounting height is 1.5m
above FFL
2) Isolate AC mains supply,
note this must be 230 Vac
and fused at 5 amps.
3) Optimum cable size is
1.5mm CSA; wiring colour
codes vary in different countries and are not defined here.
4) Enter cable to rear of back plate.
5) Securely fix back plate to wall surface or recessed back
box using holes provided.
6) Terminate conductors as per the wiring diagram on the
unit, ensuring conductors are firmly gripped beneath
square brass washer.
7) This appliance is Double Insulated and must not be
earthed except at the Earth Parking terminal provided.
8) The Industry Standard back plate has 6 holes in which to
fix to the surface of your choice. Please note that some
pressure downwards is required to lock the pins in the
Unit to connectors in the Back Plate, retain with the
captive screws at the bottom of the Back Plate taking care
not to over tighten.
