PLL (Pump Lead-Lag Control)
|
The PLL (Pump Lead-Lag) control provides a lead-lag adjustable rotation functionality to a dual pump system. In addition, it is capable of controlling two operating pumps and one auxiliary pump in a 3 pump system. The PLL checks for flow on the operating pumps. When flow fails, it will turn the auxiliary pump, alarms and solenoid valve necessary for system operation.

SCP-6 (System Control Panel)
|
The SCP-6 is designed to be used with multiple hot water boiler systems that require the control of individual boiler pumps that require pump run on. In addition, the SCP-6 can provide an interlock to combustion air, and/or a lead-lag function of two primary circulator pumps. The SCP-6 control is designed to be used as an interface between a boiler sequencing control such as a Heat-Timer HWRQ Platinum and the boiler and pumps. The SCP-6 panel will control up to six boilers, six boiler secondary pumps, two primary pumps in lead-lag mode, pump flow check, a combustion air damper/fan, a combustion air damper/fan interlock, and an alarm output.
