The Mini-MOD-CNC is an outdoor reset heating control. It is unique in its capability to lead lag two different groups of boilers, condensing and non-condensing. This design evolved from heating applications need to increase their operating efficiencies while reducing their equipment initial investment.
System Temperature Switching of Lead Group: The Mini-MOD-CNC uses a specific system set point with an adjustable switching delay. If the system temperature was below the set point, the Mini-MOD-CNC will use the condensing boiler group as the Lead Group. After the system temperature rises above the system switching set point for a specified delay period, the Mini-MOD-CNC will switch the Lead Group from the condensing to the non-condensing group.
Parallel or Normal Modulation: For the modulating group of boilers (condensing or non-condensing), an advanced PID logic has been used to provide an efficient, smooth, and adjustable modulation that can fit most applications whether the boilers are to sequence normally, one after the other, or in parallel. With numerous configurable parameters like Ignition %, Modulation Start %, Gain, Lag Delay, Soft-Off , and Last Stage Hold the PID logic can be adjusted to meet your specific heating application.
Domestic Hot Water Control with Optional Priority It can be configured with Domestic Hot Water call option. It will increase system water temperature when Domestic Hot Water is needed. In addition, it allows for optional priority of the domestic hot water over heating.
