14-10 is a device designed for prestarting heating of a diesel engine. The device is characterized by a liquid cooling system, it functions perfectly even in freezing temperatures.
A little more about PZD 14TS-10
Presented pre-heater warms up the engine due to the presence of a liquid cooling system. The device must be mounted in the cooling system itself, but heating occurs due to the combustion of the air-fuel mixture, which is located in the heat exchanger. The circulation of fluid is carried out at the expense of its own pump. The power source is the vehicle’s electrical network, and fuel is supplied directly from the vehicle’s combustible system or from a personal tank (if one is available).
How does this system work?
The main task of the device is to warm up the cooled motor before driving. The principle of operation of the PZD 14TS-10 is based on heating the liquid in the engine cooling system. The fuel mixture begins to burn, and in this case, heat is released in a special chamber. This heat is transferred through the walls of the heat exchanger, the coolant is heated and begins to circulate in the vehicle cooling system. At the same time, the PZD 14TS-10 can perfectly function in the pre-start or economical mode, but it is worth considering that in the second case, the power consumption drops noticeably.
According to the presented program, the initial purge of the combustion chamber is carried out, the glow plug is heated to the required temperature values. The candle turns on for about 90 seconds, after which air and fuel are supplied. And so the combustion process in the chamber begins, and a special flame indicator controls everything. The activity of the heater itself is controlled directly from the control unit.
The control unit PZD Teplostar 14TS-10 coordinates the temperature of the cooling mixture. Depending on the temperature indicators, the mode of the device itself is selected: “Full”, “Medium” and “Small”.
What can be said about the modes of the device?
They are as follows:
- "Full". According to the program "Prestarting", the cooling mixture begins to warm up to a mark of 70 ° C. The program "Economic" involves heating to 55 ° C.
- "Average". In this mode, the coolant is heated either above 70 ° C or above 55 ° C. Usually, this indicator fluctuates at around 75 ° C.
- "Small". The coolant should warm up to more than 75 ° C (usually 80 ° C).
If the mixture heats up more than 80 ° C, then the cooling mode is turned on and the combustion processes are completely stopped, while the pump works fully and normal heating of the passenger compartment occurs. As soon as the liquid is cooled to an index of 55 ° C under the “Pre-start” program, the “Full” mode is activated, and if cooling is carried out under the “Economic” program, then the “Medium” mode is activated.
If we talk about time, then a long full-fledged cycle of the device in the program "Prestart" is 3 hours, and in the program "Economic" - 8 hours. You can turn off the device at any time.
Where is this appliance used?
The scope is very extensive. The device is mounted in the following types of vehicles:
- vans;
- Buses
- special equipment;
- freight transport.

What can be said about the control unit of the device?
The control unit guarantees control of the device together with the control panel. The block performs the following options:
- Initial diagnosis. The device and all its components are checked for malfunctions at startup.
- Diagnostics of all processes directly during operation.
- Launch and automatic operation of the device in the programs “Economic” or “Pre-launch”. There is a transition to the above modes, depending on the temperature indicators.
- Turning off the device itself at the end of the set cycle due to the loss of the functional ability of one of the nodes, when one of the parameters goes beyond the permissible limits, when the flame breaks out in the chamber.
What does the control panel do?
It is intended for use in the structure of the heater in the form of a device that guarantees manual control of the device. The main task is to start and stop the heater in manual mode, set the duration of the program, control the fan in the heating structure of the cabin, demonstrate the state of the heater.
How does the control panel work?
To 14-10 the instruction is simple, all manipulations are carried out through the control panel. On the front side there are two key switches, an LED and a thermostat knob. The switches are designed to carry out such commands:
- launching (translates into position “|”) and shutdown (position “O”).
- choice of operating mode: “Pre-start” and “Economic”, respectively.
The handle of the switch controls the heater fan in the cabin, while the temperature of the cooling mixture should be more than 55 ° C, and the heater switch should be in the “OFF” position. Management is carried out as follows:
- If the temperature control knob is moved to the extreme left position, the fan will cease to function.
- If the handle is moved to the right position, then the fan will act continuously.
- If you put the handle in the middle, then the fan will function cyclically. The duration of one cycle is 10 minutes.
We give a small example. The fan handle is set to the position when the fan runs for 4 minutes. Then after 6 minutes it will restart and work again for 4 minutes, and so on. So it will function until the position of the handle changes, or until the heater is turned off. Each change of the handle leads to turning on / off the fan in the interval from 2 to 8 minutes.
The LED directly indicates the status of the heater:
- If it just glows, then everything is in order and the device is working;
- If blinking occurs, there are malfunctions.
- Off - heater does not work.
To turn on the heater again after an automatic stop, you will need to put the first switch in the “O” position, wait about 10 seconds and turn it on again.
What malfunctions does the LED indicate?
It is very convenient that there is an explanation of the error codes PZD 14TS-10. Motorists do not need to rack their brains, thinking what is wrong with the system. Just watch the LED and count the number of blinks. You can make a note for yourself, where all the errors of the PZD 14TS-10 are explained, and leave it in the car so that it is always at hand. The following is a detailed analysis of typical faults and briefly describes how they can be fixed.
Error codes 14-10 |
| Number of blinks | Description of the problem | How to fix the problem |
1 | The heat exchanger overheats, the system recognizes a large difference in temperatures that are measured by the overheating sensor and the temperature sensor | An overheat sensor or a temperature sensor shows a temperature reading of more than 102 ° C. What is to be done? You will need to check the functionality of the circulation pump, as well as the fluid circuit. If there is a temperature difference of more than 20 (for example, the temperature from the overheating sensor is more than 85 ° C, and from the temperature sensor it is more than 75 ° C). In such situations, it is recommended to double-check the sensors; if necessary, replace them. |
2 | Start attempts have been exhausted | If the permissible number of attempts to start has been exhausted, you will need to check the fuel volumes and its supply system. It is recommended to check the air supply system for the combustion of fuel, as well as the exhaust pipe. |
3 | Flame interruption observed | Recheck the amount of fuel and its supply system. It is recommended to inspect the air supply system for the combustion of fuel. If the heater turns on, then you need to check the flame indicator, and in case of malfunction, replace it. Clogging in the fuel filter is also possible; it is recommended to inspect it. |
4 | Malfunction of the glow plug, there may be a breakdown in the air blower motor | It is required to check the efficiency of the glow plug: if it is broken, then a replacement is necessary. It is recommended to check the wiring of the air blower motor. If it is broken, a replacement is needed. |
5 | Malfunction in the flame indicator | It is required to inspect the wiring, check the resistance between the contacts of the indicator connector. If the indicator is above 90 Ohms, you have a break. If the indicator is less than 10 ohms, a short circuit. One way or another, the flame indicator will need to be changed. |
6 | Overheating sensor damaged, temperature sensor | It is required to inspect the connecting wires. The output signal and voltage are linearly dependent on temperature. 0 is 2.73 V, when the temperature increases by one degree, the output signal by 10mV will increase. Sensors will need to be checked and, most likely, they need to be replaced. |
7 | Circular pump fault | Inspect the circuits of the circular pump, check for a short circuit, inspect the pump itself, and replace if broken. There should not be an open circuit in the electric circuits, if this is observed - change them. If a short circuit is detected, repair it; the relay will need to be replaced if necessary. |
8 | There is no communication between the control unit and the remote control. | Inspect all connecting wires and connectors. |
9 | Overvoltage, shutdown. Maybe, on the contrary, undervoltage, shutdown. | Inspect the battery, wiring, and voltage regulator. Input voltage should not be higher than 30.8 V and not lower than 20 V. |
10 | Exceeded ventilation time. | The heater has not cooled sufficiently in the allotted purge time. You will need to double-check the air supply system for fuel combustion. Check also the flame indicator, if necessary - change. |
As you can see, the error codes for Teplostar 14TS-10 are different, it will be difficult to remember everything, so you can make a note or a printout with all the explanations.
