Autonomy errors Planar 44D-12-GP-S 44D-24-GP-S
| The code | Malfunction | Cause of error |
| 01 | Exceeding the permissible temperature of the heat exchanger. | The temperature sensor sends a signal to turn off the autonomy. The heat exchanger in the sensor installation area has reached a temperature of over 250?C. |
| 02 | Possibility of overheating. Overheating near the control unit in the heater itself. | There is not enough cooling during the purge or there is overheating of the control unit during operation. |
| 04 (06) | Temperature sensor error in the control unit. | Failure of the temperature sensor (located in the control unit, there is no possibility of replacement). |
| 05 | Flame indicator failure. | An open in the electrical wiring or a short circuit to ground (case) of the indicator. |
| 08 (29) | The flame is interrupted during operation. | Leaks in the fuel supply line, failure (wear) of the fuel pump or flame indicator. Pollution of pipes for air supply or exhaust gases. |
| 09 | Problems in glow plugs. | Breakage or short circuit of the wiring, failure of the control unit. |
| 10 | The electric blower motor does not reach the required speed. | Electric motor breakdown. Lack of lubrication in the bearings or contact of the impeller with the volute in the supercharger. |
| 12 | Shutdown, voltage exceeds 16V (above 30V for 24V device). | Failure of the battery or voltage regulator. |
| 15 | Shutdown, voltage below 10V (below 20V for 24V device). | Failure of the battery or voltage regulator. |
| 13 | The device does not start after two attempts. | There is no fuel in the tank.
The quality of the fuel does not correspond to the conditions of use in cold weather. Lack of fuel. Contaminated air intake or flue gas piping. Poor heating of the glow plug, failure of the control unit. The impeller is in contact with the volute in the blower, causing insufficient air to be supplied. Contamination of the hole in the combustion chamber (diameter - 2.8 mm). Contamination of the candle grid or incorrect installation in the fitting (not all the way). |
| 17 | Fuel pump error. | Open or short circuit in the fuel pump electrical circuit. |
| 20 | There is no communication between the control unit and the remote control. | Failure of the fuses in the power circuit. The remote control does not receive information from the control unit. |
| 27 | The motor is not spinning. | Jamming as a result of the destruction of the rotor, bearing, or the ingress of various objects.
Oxidation or corrosion of contacts in the block. |
| 28 | The engine rotation speed does not change, it does not respond to control commands. | Failure of the electrical control board of the motor or control unit. |
| 29 | The flame is interrupted during operation. | Leaks in the fuel supply line, failure (wear) of the fuel pump or flame indicator. Pollution of pipes for air supply or exhaust gases. |
| 30 | There is no communication between the control panel and the unit. | The unit does not receive information from the control panel. |
| 78 | Flame failure detected during heater operation. | Airing of the fuel supply system, failure of the fuel pump or flame indicator.
Leaks in the fuel supply line, failure (wear) of the fuel pump or flame indicator. Pollution of pipes for air supply or exhaust gases. |
* in parentheses is the new error code.
