with the Copper Brute II is installed in the piping or tank, per the suggested piping diagrams, and connected to the “S C2” and “SUP S” terminals. See Section 6.3 for “Mode” definitions and Figures 22 to 24 for field wiring schematics.

Outdoor Reset Sensor: The outdoor reset sensor, if used, is connected to the “OD S” and “S C2” terminals.

Field Installed Pump: A pump contactor can be wired to the “PMP” and “PMP” terminals (these terminals supply 24VAC to close the contactor whenever the boiler pump would be operated). NOTE: In some cases, the boiler pump is operated continuously.

External Alarm: An external power supply and alarm can be connected to the “ALRM” and “ALRM” terminals. In the event of an ignition system lockout, a contact closure occurs across these terminals.

External Heat Demand Indication: 24VAC is present across the “HT OUT” and “LWCO GND” terminals whenever the temperature control sees a system heat demand. This can be used to power a contactor (0.5 Amp, maximum) for devices operated whenever the boiler could fire (combustion air fans, motorized louvers, etc.) NOTE: In some cases, the temperature control will always see a heat demand in the system, such as when the “Ht D” and Com D” terminals are jumpered.

Other Field Interlocks: To install other field-

wired devices to interlock with the boiler (louver switches, flow switches, etc.), remove the jumper between the “COM” and “NO” terminals and wire the device in series across these terminals. (See Section

5.3for important information about external staging controls and building automation systems.)

System Heat Demand: Remove the jumper across the “COM D” and “Ht D” terminals, and con- nect the zone pump or valve end switch, thermostat, aquastat, or other indication of system heat demand to these terminals. If no indication of a system heat demand will be provided, the jumper must remain in place. When jumpered, the temperature control will always see a heat demand, and the Copper Brute II pump (if equipped) or any pump with its contactor connected to the “PMP” and “PMP” terminals will run continuously. In addition, any device connected through the “HT OUT” and “LWCO GND” terminals for an external indication of the heat demand will run continuously. See Section 6 for more information on the system heat demand for various modes of operation.
