additional components.

Improper field wiring may result in fire or explosion 

which can cause property damage, severe injury, 

or death. Make only wiring connections which are 

in accordance with the Installation and Operation 

manual.

Un câblage incorrect lors de l’installation peut 
causer un incendie ou une explosion pouvant 
entraîner des dommages matériels, de graves 

blessures ou la mort. Ne faire seulement que les 

connexions conformes au Manuel d’installation et 

d’exploitation.

The wiring methods in this section must be 

used to connect an external staging control, such as a 
multiple boiler control, building automation system, 

energy management system, etc.)  Other wiring 

methods may be unsafe.

Figure 15

 shows how to wire the external 

controller to the Copper Brute II’s field wiring panel, 
which is located on the right side of the Copper Brute 

II.

Most of the time, the number of stages from the 

external control will match the number of stages on 

the Copper Brute II.  However, in some instances, the 
controller will not have enough staging capability to 
work with all of the stages on a Copper Brute II unit 

(for instance, using an 8-stage external control with 

four 4-stage Copper Brute II units.)  In these instances, 
it is very important to follow the instructions in this 
section  

Figure 15

 shows how to combine stages on the 

Copper Brute II for those instances when the external 

controller cannot control all the stages available.

NOTE:  The only time Copper Brute II stages should 

be jumpered is when the Copper Brute II has an 
external control, and the Copper Brute II is used in 

Mode 6.  In all other modes, when the Copper Brute II 

controls its stages, the terminals shown in 

Figure 15

 

must NOT be jumpered.
