External EMS Connection to Terminal Strip for Stage Firing Control of Burners

This unit is equipped with a factory installed terminal strip for connection of an energy management system (EMS) to the burner stages. The EMS terminal strip is located in the unit's junction box. Ensure that all wiring used for connection to this terminal strip is properly sized per the recommendations in TABLE-L. When connecting an EMS to this terminal strip to sequence on each stage of burner operation, the unit's internal thermostat or electronic sequencer should be set as an additional high limit control. This will prevent problems between the set points of the EMS and the boiler's internal controller.

Figure 23A - Models 495,000 - 745,000 Btu/hr Control Panel Component Location Drawing

Figure 23B - Models 985,000 - 2,065,000 Btu/hr Control Panel Component Location Drawing

Figure 24A shows the position of jumpers as shipped from the factory for stand-alone operation of boilers or water heaters.

Figure 24B shows connections to the terminal strip for Remote ON/OFF control of the boiler or water heater. The 1C-1NO jumper must be removed when making these wiring connections. This remote ON/OFF control will provide an Enable/Disable signal to the unit and allow the unit to operate based on the stage set points, until the remote ON/OFF signal is cancelled.

Figure 24C shows the connections necessary to operate the unit as a two-stage (High/Low Fire) boiler or water heater from an Energy Management System (EMS). The actual set point temperatures are controlled by the EMS. The High Fire Offset on the electronic temperature control in the unit must be set to zero and the set point must be set to a value which will function as an upper limit for proper operation under this two-stage control from an EMS.

Figure 24D shows the Continuous and Intermittent terminals. External safety devices connected to these terminals will function to protect the unit. Devices connected to the Intermittent terminals (B1 and B2) are monitored only when there is an active Call for Heat. Devices connected to the Continuous terminals (A1 and A2) are monitored continuously and will activate an alarm (if the unit is equipped with the alarm option) anytime the safety device senses an abnormal condition. An additional wire may be field-installed from these safety devices to terminals A3 or B3 (as appropriate) to activate an alarm (if the unit is equipped with the alarm option).
