Button: MENU/Set Point/Offset/..../Maximum Water Temperature
• This is the highest temperature heating water the Mini-MOD will circulate through the
heating system. It is available in Reset mode only.
• When using a radiation system, it should be set according to the tubing or floor
manufacturer's specification.
• The Maximum Temperature must be at least 20°F higher than the Minimum Temperature
(See previous setting).
• The Maximum Temperature must be set lower than the boilers high limit for correct system
temperature control.

Adjustable from -10 to +10
Button: MENU/<System Settings>/Gain
• The Gain adjusts the aggressiveness of the Mini-MOD PID logic. It controls how much
modulation is changed when the system temperature is different from the Set Point.
• A Gain of 0 is a good starting point for all systems.
• If during normal load conditions, the system temperature tends to oscillate significantly,
decrease the Gain by two numbers (for example, from 0 to -2). Wait for at least 15 minutes
before evaluating how the change has affected the system.
• If, during normal load conditions the system temperature tends to remain consistently below
the Set Point (or consistently above the Set Point), increase the Gain by two numbers (for
example, from 0 to 2). Wait for at least 15 minutes before evaluating how the change has
affected the system.
