startup sequence
Button: MENU/<System Startup>
• When powered, the Mini-MOD-CNC 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-CNC has already been configured.
• The System Startup menu sets the main parameters that relate to the heating application.
These settings must be set by the installer.
sensor type
Reset °F, Reset °C, EMS °F, EMS °C
Button: MENU/<System Startup>/..../Sensor Type
• The same Heat-Timer temperature sensor can display in either °F or °C.
• If any of the Reset options is selected, the control will use outdoor reset to calculate the
Target Temperature.
• If any of the EMS options is selected, the control will require the use EMS 4-20mA Interface
(HT# 926741-00).
• Selecting any of the °F options will display all temperatures in degrees Fahrenheit.
• Selecting any of the °C options will display all temperatures in degrees Celsius.

Adjustable from 0ºF/ -18ºC to 200ºF/ 94ºC
Button: MENU/<System Startup>/..../Sensor Type/Switch Setpoint
• It is the Target Temperature Set Point at which the Mini-MOD-CNC will switch between
Condensing Boiler Group and Non-Condensing Boiler Group.
• The Condensing Boiler Group will be the lead group when the Target Temperature is below
the Switch Set Point. However, the Non-Condensing Group will be the lead group when the
Target Temperature is above the Switch Set Point.
