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

Reviewing Setpoint Temperature:
•Press or to review the Setpoint
temperature.
When any program is running, the LCD will show
the program Setpoint temperature with the "SET"
indicator displayed.
When operating in Frost protection mode, the LCD
will show 5°C with the Frost Protection indicator
displayed.
When operating in Temporary Override mode, the
LCD will show the temporary Setpoint temperature
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 in Normal mode 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.

The installer should select the jumper positions required
if changing from the factory presets-these jumpers are
found on the rear of the unit.
1) Select a suitable location
2) Remember to Isolate AC

Receiver must be put to the UP position.
2. Disconnect AC power and
remove batteries
prior to adjusting
address code.

Frost Protection:
•Press and hold BL/FROST in Normal mode for 3

Receiver must be put to the UP position.
2. Disconnect AC power and
remove batteries
prior to adjusting
address code.

• 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
