Device
The design of the Protherm Cheetah 23 MTV boiler has a basic composition of assemblies and structural elements typical for most convective installations of this type.
The main units of the unit include:
- Chromium-nickel alloy gas burner.
- Primary copper heat exchanger.
- Hydraulic group, which includes a three-way valve, water make-up and discharge devices, and other elements.
- Secondary stainless steel heat exchanger.
- Grundfos circulation pump.
- Turbocharger fan.
- Expansion tank with a capacity of 5 liters.
- Electronic control board with microprocessor connected to an external display panel.
- Self-monitoring sensor system, which continuously monitors the state of all boiler elements and signals about errors.
The boiler operates according to a typical scheme. The heat carrier enters the heat exchanger, where it is heated to the maximum temperature.
Then it is removed and enters the secondary heat exchanger, where hot water is heated. After that, the liquid enters the three-way valve, partially mixes with the return flow and acquires the set temperature corresponding to the set heating mode. The extract air then flows out to the external heating circuit.
Heating is provided by a gas burner, which automatically starts or stops when the set temperature limits of the coolant are reached.
The air supply for the organization of optimal combustion is provided by a fan, which simultaneously creates a draft for the removal of gas combustion products. Air intake is made from the external compartment of the coaxial chimney, purchased separately.
The operation of all units is monitored by a system of sensors that monitor the presence of a flame, gas or water pressure, signal all failures or malfunctions. The occurrence of any problems is immediately indicated on the display by an alphanumeric code indicating this or that error.
A complete list of codes is available in the user manual..

- error is not indicated in case of inactive equithermal regulation function (E-)
- in this case, the boiler continues to work in normal heating mode (without equithermal regulation)
RECOMMENDATIONS
- Check sensor connection
- Check sensor cables
- Check circuit voltage
- Check sensor Resistance (replace if necessary)
Error f20 on the Proterm Scat boiler
- malfunction is indicated in case of activation of the emergency thermostat as a result of boiler overheating
- the message will be automatically deleted after manually resetting the emergency thermostat
This emergency thermostat should also be installed in the copper pipe.
This thermostat is installed in older versions of the boiler, in boilers that come after 2012 this thermostat is not
there is a thermostat on the heat exchanger
- remove the protective rubber sheath from it
-in the middle you will see a small red button, press it and collect everything in reverse order. But find the cause of the overheating.
Not only press, but also identify the cause of overheating, why it happened. !!!
There is no circulation, check the pump and the air in the system. , there may be air in the heat exchanger, etc. To check the pump, unscrew the air bleed plug (you can see it visually or touch it with a screwdriver) The pump is Wilo. If it is broken and does not rotate, replace it. So that it would be more economical to buy one head, and not the entire pump assembly
Overheating just doesn't happen.
RECOMMENDATIONS
- air in the boiler heat exchanger
- Check the heating pump (no flow through the unit)
- Check overheat thermostat
Types of boilers
There are two models of boilers Cheetah:
- Atmospheric (with an open combustion chamber and natural smoke extraction).
- Closed or turbocharged (a fan is used to supply air to the combustion chamber and forced removal of exhaust gases).
Models with an atmospheric burner are not recommended for installation in kitchens due to the possibility of a smoke smell due to external influences. For example, a strong wind or icing of a chimney can cause a decrease in draft, fraught with smoke in the room.
It is advisable to install atmospheric units in separate chambers with high-quality ventilation.
Turbocharged boilers are completely safe and can be installed in residential areas or in the kitchen.
They are guaranteed to remove exhaust gases, allowing you to keep the indoor air clean..
Both options have a full-fledged self-diagnosis system that constantly monitors the status of all nodes and immediately notifies about emergency situations.
F.22 - Loss of water - insufficient water pressure in the heating system
- a malfunction is indicated if the water pressure in the heating system drops below 0.6 bar
- the message will be automatically deleted after the heating water pressure in the system rises above 0.6 bar
- as a result of adding water to the heating system
- an error message will not appear in the event of a pressure sensor malfunction
The pressure sensor is used to determine the water pressure in the boiler (heating system). In the event of a lack of heating water in the boiler, the pressure sensor will transmit information to the boiler control board, which will give a command to stop it.
Operating principle
As the water pressure rises, the volume of the membrane carrying the magnet will increase. Opposite the magnet there is a Gall sensor, which changes the input voltage on the boiler control board, depending on the change in the parameters of the magnetic field. The change in the parameters of the magnetic field depends on the change in the distance of the Gall sensor in relation to the position of the magnet Measurement points
Pressure sensor input voltage:
Measuring points 1 and 2 = 5 V DC Test values: Measuring points 1 and 3 At 1 bar / 1.7 V DC At 1.5 bar / 2 V DC At 2 bar / 2.3 V DC
RECOMMENDATIONS
- Water pressure too low 0.3 bar. When filling the boiler with water, in this case it is not necessary to press the RESET button.
- Faulty water pressure sensor. Replace.
- Check for leaks in the boiler and heating system.
- Check if the pump is working properly. It is possible that the pump may be blocked. disassemble it and check for proper operation and cleanliness.

F.41 - "Sticky" relay Proterm skat
- - this message will appear in the case of a 5-fold unhurried attempt of the boiler to "unstuck" the relay
In such cases, a LED will flash on the boiler control panel. The boiler will try to break the relay, and in case of failure, the display will show the error message F41. The boiler will run at minimum heat. After switching off and on again, the boiler will start working in operating mode, but the LED will continue to flash on the display. Contact a specialized service organization.
- the message will disappear after the boiler is switched on and off again
- the presence of a problem with the "sticky" relay after the boiler is switched on again continues to be signaled by the blinking of the HDO LED
- the message will disappear after updating the boiler factory settings stored in the EEPROM memory (code d.96)
- the error image is eliminated by switching off and again
turning on the boiler
- when switched on again, the boiler signals a sticking relay
flashing HDO LED
Verification:
- When the command to heat the heating water is canceled - at the end of the heating water cycle (opening the RT circuit) or hot water supply (the water temperature in the storage tank has reached the set value).
When the "programmable temperature limiter" is activated, i.e. if the set temperature is exceeded by 5 ° C. Note: This function is activated when the boiler is in "standby" mode (ie there are no commands). The function starts when the detector is activated. If the boiler operates with a jumper and an external temperature sensor without heating the hot water supply, then a similar problem with the relay can be ignored until the temperature of the water in the system calculated by the equithermal regulation unit is exceeded by 5 ° C. Relay sticking test does not depend on the boiler operating mode. It is linked to the current state of the heating function. While the latter is disconnected, and the relay status is checked. The boiler is in a similar state whenever the heating elements stop working, i.e.: 1. after canceling the commands for heating the heating water and preparing the hot water supply, activating the anti-frost protection system - heating. 2. when activating the programmable temperature limiter - setpoint + 5 ° C Note: In case of a detector triggering (for example, in case of accidental closure of a relay contact), the function is activated (that is, similar to the one described in point 1). In addition, the function is activated in the following cases: DHW: cases 1 and 2 RH may occur: room thermostat - 1 and 2 RH: jumper + external temperature sensor
