1Introduction
The MB250 Controller is a device to manage stoves and boilers with automatic ignition and pellet loading.
The operation of the heating system is determined by reading the exhaust temperature, water temperature,
and through the acquisition of the parameters setup by the user. The parameters of the controller are fully
configurable inside the menu. By setting the parameters it is possible to:
modify the operation of the heating system according to the user’s specific requirements
modify the operation of the controller to a suit any stove or boiler
This manual illustrates in detail the controller installation steps, the configuration, the functioning and the
technical characteristics.

3Installation
Connections
In the below picture is showed the connections of the main board and its outputs and inputs.
Follow the indications of the connection modalities for a correct installation.
For a correct and secure functioning connect always ground connection
For a correct operation follow carefully the modalities of connection indicated to
avoid damage to electronics
Make connection in a tidy way; keep separated cables of low voltage (probes,
contacts, control panel flat) and cables of high voltage (power source, loads) to
reduce interference problems

First Configuration
First of all, set parameter P42 to choose the Hydro or Air modality (see par. 7.15). If the Hydro modality is
set, select the plumbing plant (parameter P26 in the Default Settings Menu of the Technical Menu). Then
set the configurable outputs via parameters of the Default Settings Menu P44, P48and P36, then set the
parameters P70, P71,P73, P74, P75 and P76. Finally set the parameters P25 to choose the Combustion
Fan type (with or without encoder) and P81 to choose the Auger type (with or without encoder).
Set also the parameter PA44 to define the NTC probe to connect to input IN4.

When the system detects a different input configuration error message Er56. For the actual setting of the
system, if plant 10 is selected or the existing probes configuration is modified, follow this steps:
1. set the parameters: P26=10
P74 or P75 or P76=8
P74 or P75 or P76=9
P36 or P44 or P48=14
2. put the system in Off state
3. cut off the power
4. make the appropriate changes to the inputs Buffer probe and DHW probe
5. restore power
6. control in Views menu if the temperature detected by the present probes coincides with the setting
made
7. repeat all operation from step one if necessary
