3.3 Control Functions
This menu options sets the type of control for the unit to suit the application and
determines how the voltage output operates in the Night setback and the Emergency
conditions.
a. Action of controller :-
Damper
• Display value above the set point the output voltage increases => 10 V
• Display value below the set point the output voltage decreases => 0 V
Inverter
• Display value above the set point the output voltage decreases => 0 V
• Display value below the set point the output voltage increases => 10 V
b. Min/Max and Limit settings:-
Direct Action
• Max Output: Output voltage increases => 10 V
• Minimum Output: Output voltage decreases => 0 V
• High limit: Output voltage increases => 10 V
• Low Limit: Output voltage decreases => 0 V
Reverse Action
• Max Output: Output voltage decreases => 0 V
• Minimum Output: Output voltage increases => 10 V
• High limit: Output voltage decreases => 0 V
• Low Limit: Output voltage increases => 10 V
