ST625TX INSTRUCTION MANUAL
PAIR MENU
The PAIR mode allows the ST625TX thermostat and
receiver to communicate with each other.
On entering the menu, scroll to select the preferred option
(Pairing ON or OFF), and confirm the choice using the
OK button.
Please consult the Installation section of
this manual for full instructions on how to Pair the
ST625TX units.
BATTERY STATUS
The ST625TX checks the battery voltage frequently during normal operation. If the
battery voltage is sensed as being low, the low battery indicator will be displayed
on the screen. Although the programmable thermostat will continue to operate
normally at this stage, you should replace the batteries as soon as possible to prevent
the ST625TX entering OFF mode.
OFF MODE
The Low Battery indicator will be displayed if battery voltage is detected as
“low”, in this case the thermostat functions normally during battery low except the
backlight is turned off. The ST625TX will enter into OFF mode if the battery voltage
falls drastically low, and all outputs will turn off.
As all functions except sampling the battery voltage are disabled in OFF mode, it is
recommended that you replace the ST625TX batteries as soon as possible to restore
normal operation. If the voltage of the replaced batteries is not high enough (if older
batteries have been used) the unit will remain in OFF mode and will not reset.
