A good practice after performing
any Startup menu modifications
is to check all operating settings

Mini-MOD
startup sequence
Button:
MENU/<System Startup>
• When powered, the Mini-MOD performs a self diagnostics-test on its components.
• On the first power up, the System Startup screen will appear after the initialization is
complete. If it doesn’t, the Mini-MOD has already been configured.
• The System Startup menu sets the main parameters like the type of sensor, the type of
output, and the modulating mode.

• Reset mode is only available if an outdoor sensor is connected to terminals 25 and 26. DO
NOT select Reset without an outdoor sensor.
• The same Heat-Timer temperature sensor can display in either °F or °C.
• If °F is selected, all temperatures and settings will be displayed in degrees Fahrenheit and
the Mini-MOD will operate as a Set Point Control in degrees Fahrenheit.
• If °C is selected, all temperatures and settings will be displayed in degrees Celsius and the
Mini-MOD will operate as a Set Point Control in degrees Celsius.
• Set point mode does not require an outdoor sensor. If an outdoor sensor is connected in Set
Point mode it will be used only as an outdoor cutoff point. That is, to turn the boilers and
system pump off.

• This allows the Mini-MOD to receive an external set point from an EMS/BMS system.
• You must select the 4mA (min) and 20 mA (max) Set Points in the following screen.
• The 4mA can be set to any temperature between 70ºF to 200ºF.
• The 20mA can be set to any temperature between 90ºF to 240ºF. However, the minimum
must be 20ºF higher than the 4mA setting.
• Connect the 4-20mA EMS Control Interface to the Mini-MOD RS485 connection.

• Outputs can be configured to 4-20mA operation (current) or any of the voltage ranges (0-5V,
0-10V, 1-5V, 2-10V). Check the modulating motor to determine its control requirements.
• When using Extension panels, connect them prior to configuring the Output Type.
Otherwise, the Mini-MOD might not recognize them properly.
• Select the appropriate Output Type for each of the boilers. The Mini-MOD can have a
different Output type for each boiler.
