Regulator with lambda probe for gasification boilers for wood and wood briquettes
Regulator AK5000
The operation of PYROGAS gasification boilers is controlled by a modern AK5000 electronic controller together with a Bosch LSU 4.9 Lambda probe and two BELIMO CM24 servomotors for primary and secondary air supply, which meets all the requirements for easy operation and high comfort.
Safe operation of the boiler is ensured by 2 safety thermostats and a safety exchanger against overheating.
1. 128 x 64 pixel graphic display with LED backlight for displaying the boiler status
2. ▲ button - switching the display of current measured values, functions or increasing the set value
3. ◄ button - switching off the exhaust fan or moving the selection to the left
4. ► button - selecting back (ESC) or moving the selection to the right
5. button - switching the display of current measured values, functions or reducing the set value
6. ENTER button
short press
- switching on the boiler, displaying the rotary knob and then switching off the boiler or adding fuel (fan at 100%)
- ending the addition of fuel - if it was in the addition state
- moving to the selected menu level, confirming the choice, type or save value
long (2s) press – transition to user settings of boiler automation
7. duoLED – overall status OK (green) / Error (red)
Combustion process regulation:
- PID controller with flue gas temperature correction optimally maintains the set temperature of the boiler outlet water by continuously controlling the fan speed
- Correction of the combustion process to flue gas temperature significantly reduces inefficient heat loss from the boiler
- Intelligent control of the boiler water pump
- Optimization of the combustion process by regulating the supply of primary/secondary air to the firebox based on flue gas analysis with a Bosch Lambda probe brings:
- increased efficiency of energy use in fuel
- reduced emissions
- fuel savings of up to 20%
-
User comfort - Graphic display
- Simple, intuitive control
- Accelerated boiler start-up to operating temperature
- Minimization of flue gas leakage into the environment during fueling by identifying the opening of the fueling chamber door
- Identification of fuel burnout
- Minimization of electricity consumption in Stand-by mode
- Software upgrade option
-
Regulatory options of the basic set - Regulation according to room thermostat
- Control of UK storage tank charging
- Priority DHW regulation
- Switching on an external boiler (gas/electric/pellets, etc.) after fuel has burned out
- Control of the pellet burner (for combined boilers)
- Note: for the above-mentioned use of the regulation options, it is necessary to add the appropriate sensors / valves / servos
-
Technical parameters of the basic set - Power supply 200 – 255 VAC, 50Hz
- Graphic display
- Stand-by mode consumption below 0.1W
- 4 thermometer inputs, configurable for different types of thermometers (semiconductor sensors KTY, Pt1000)
- 1 binary input (opening the loading chamber door)
- 1 input for connecting an emergency thermostat / STB
- 1 Relay output for switching the circulating water pump
- 2 modulated outputs for switching fans (pressure / exhaust)
