Controlling Function Description

Button Instructions

Power button

In any case, it will be turned off when long pressing for 2 seconds and no output no display. After the power is off, quickly press to restore the power-on state. In the power-on state, quickly press the button, it will turn on or suspend outlet power.

Set controlling temperature

In normal working mode, quickly press to enter the settings of temperature controlling state, at this time T1 setting temperature flashes, press or button to increase or decrease the setting temperature value, quickly press to confirm the T1 setting value, and enter the T2 setting, T2 setting temperature flashes, press or to increase or decrease the setting temperature value, quickly press to confirm saving and exit the setting of temperature controlling state. And if there is no action for 10 seconds, it will automatically exit and save the data.

The default value of T1 is 77.0°F or 25.0°C, the default value of T2 is 78.0°F or 26.0°C, and the temperature range of T1 and T2 is 0.0℃~45.0℃ or 32.0℉~113℉.

Menu Parameter Setting

In the normal working mode, press the button for 2 seconds to enter the menu parameter setting state. At this time, T1 displays the menu code, T2 displays the menu setting value, presses to scroll down the menu option and saves the previous menu parameter, then presses or button to change the current setting value. In the setting state, long press for 2 seconds or without operation in 30 seconds, it will exit the setting state and save the parameters, then return to the working mode.

Control Function Description(TS1/TS2)

When the controller is working normally, the controller will automatically select the smaller temperature value of the two settings TS1 and TS2 to start the heating, and will stop heating when the temperature reach the larger one (the minimum absolute value of TS1 and TS2 is 0.3 °C or 0.5°F)

High/Low Temperature Alarm(AH,AL)

When measured temperature ≥the setting value of high temperature AH, it will alarm and turn off heating output. The screen will rotate to display“AH”and current temperature, buzzer will ”bi-bi-Biii”, until the temperature < AH, buzzer will be off and return to normal display and control. Or press any button to only turn the buzzer alarm off.
When measured temperature ≤ the setting value of low temperature AL, it will alarm. The screen will rotate to display“AL”and current temperature, buzzer will“bi-bi-Biii”, until the temperature > AL, buzzer will be off and return to normal display and control. Or press any button to only turn the buzzer alarm off.
High and low temperature alarm will be pushed to mobile APP and remind the customer that the product is in alarm state.=

Continuous Heating Time Alarm(CT)

When measured temperature ≤ the starting heating temperature, the output control is turned on. If the continuous heating time arrives, but the measured temperature has not risen to the stop heating temperature, at this time the heater is abnormal or the probe is abnormal, and the output is forcibly turned off. PV will show E5, the buzzer keeps ringing, and the alarm status is pushed to the mobile APP to remind the customer that the product is in an alarm state and need to check in time.

When CT = 0, it means that the continuous heating alarm function has been cancelled.

Temperature Calibration(CA)

When the measured temperature deviates from the standard temperature, the temperature calibration function can be used to calibrate the measured value consistent with the standard value. The calibrated temperature = the measured temperature value + the calibration value.

Fahrenheit or Celsius Setting(CF)

Support setting Fahrenheit or Celsius. The default temperature unit is Fahrenheit. If you need to display the unit in Celsius, please set the CF to C and note that when the CF is changed , all setting values will be restored to the default setting and the buzzer will beep.

Setup Guide

To set up the Inkbird C929-A, begin by connecting the device to your Wi-Fi network using the Inkbird app.

Once connected, attach the sensors to their respective ports on the controller.

Abnormal Situation

Temperature Abnormal: The temperature difference between the two temperature probes is greater than or equal to 3℃/5℉.
Probe Abnormal: Any probe is not inserted properly, or there is an open and short circuit in the probe or the wire.
Heater Abnormal: The heater is heating but the water temperature is decreasing.

Note: When the product is abnormal, the PV display will show as follows:

Er&E1&E2: Temperature Probe Abnormal
E4: The temperature difference between the two temperature probes is greater than or equal to 3℃/5.0℉
E5: Continuous Heating Time Alarm
