Heat-Timer Mini-MOD-CNC

Heat-Timer Mini-MOD-CNC Heat-Timer Mini-MOD-CNC 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.

    Outdoor Temperature Switching of Lead Group: The Mini-MOD-CNC provides two means of selecting the Lead Group switching, either using a specific system or outdoor set point with an adjustable switching delay. If using the outdoor temperature as the switching mechanism and the outdoor temperature was above the set point, the Mini-MOD-CNC will use the condensing boiler group as the Lead Group. After the outdoor temperature drops below the outdoor 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.

    System Temperature Switching of Lead Group: When using the System Temperature Set Point as the switching mechanism and 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.
