TEMPERATURE ALARMS- PROGRAMMING CUSTOMISED

PRESETS

To customise the preset alarm temperatures, press and hold the

desired alarm button (sensor #1 or sensor #2). You are now in the

MAX temp. alarm set mode and may adjust the maximum

temperature by using the "+" or "-" buttons. Press the alarm button

again to confirm your setting for the minimum alarm temperature and

to exit the entire alarm preset temperature mode. Repeat this

process to set the other minimum and maximum alarm temperatures

for the other remote sensor.

TROUBLESHOOTING

If batteries are installed the main unit will display "- - " until it

acquires the wireless signals from the remote sensor units. If the

unit still displays "- - " the remote units' batteries may be dead or the

main and remote units cannot synchronize wireless signals. Try

moving the main unit to a different location.

ERROR DISPLAY

If the unit displays "-E-" then this is an error condition and the

receiver has not received a signal from either sensor #1 in the last 4

hours or from sensor #2 in the last 3 hours.

To remove the "E" from the display it is necessary to reset both the

receiver and transmitters at the same time. This can be done by

either removing batteries of each unit or using a small paper clip or

pin, and poke it through the reset hole located on the rear of the deg

C/F switch. The unit will display - - - on both channels then start

reading temperature after a minute or so.

If the product doesn't display the temperature then it will be

necessary to move the receiver closer to the sensors and/or replace

the batteries.

Please note that the maximum recommended range is 15metres

due to the wall thickness of refrigerators/freezers.

LOW BATTERY INDICATOR

A low battery indicator is shown in the display window for the remote

sensors. When the low battery indicator displays, replace the

batteries with fresh ones. Be sure to never mix old and new

batteries, and never mix battery types such as alkaline and lithium

together.

CHANGING BATTERIES

If it is necessary to change the batteries of the sensors and if there

are two units in close proximity, then batteries will need to be

changed within eight minutes to avoid the base station picking up

readings from alternative sensors.

IP RATING

This product has an IP54 rating. Note: The product cannot be

submersed in water or any other liquid.

Temperature Measurement Range:

MAIN UNIT: - 30ºC to + 40ºC / -22ºF to 104ºF

NOTE: If the remote sensor units are measuring temperatures

above the temperature range the main unit will display "-H-". If the

remote sensor units are measuring temperatures below the

temperature range, the main unit will display "-L-".
