7. Trouble Shooting:
A. Output device does not turn on when specified temperature is reached.
Firstly please understand that the controller turns off the load when the target temperature is reached. It
turns on the load only when the specified temperature is then exceeded. The load will be turned on only
when the temperature is OVER (SV - Hd) or BELOW (SV + Cd).
Then, check if a PT value is specified. If you’ve specified a PT value, during the delay time, the indicator on
screen will flash. Your device will be turned on after the specified time delay.
B. The controller displays EEE while beeping.
Please check if the 3.5mm plug of the sensor probe is inserted completely into the jack on side of the
controller. If plugged in correctly, the probe is most likely defective. Please email us at [e-mail]
for a free probe replacement.
C. The screen displays LLL.
This means the temperature is below the minimum value that this controller can measure.
D. The screen displays HHH.
This means the temperature is over the maximum value that this controller can measure.
E. It keeps beeping when the temperature reaches a certain level.
This is usually because the alarm has been set, be sure AH and AL are each set to 0. When the alarm sounds
press any key to disable it.
WARNING
※ The sensor probe is waterproof. But the controller is not waterproof. Don’t get water into the outlet.
※ Rated Current of this controller is 15A (1650W @110V, or 3300W @220V). Check amps and watts of
the refrigeration and heating equipment in order to reduce the risk of fire caused by overloading. The
refrigeration and heating equipment don’t work at the same time. So you just need to make sure each
one individually doesn’t overload.
