DHW - Domestic Hot Water is used to con gure the DHW
temperature parameters for water heaters (BNTV) and for
indirect water heaters that are used with boiler (BNTH)
systems.
8.7.5 Warm Weather Shutdown
Con guration
From this sub-menu you will be able to enable/disable the

minimum and maximum modulation rates will affect the
overall ratio of the boiler. The installer level password will
allow changes to these parameters. Consult the factory if an
adjustment is needed to any of these parameters.
8.7.8 Pump Connections
The controller in the Brute energizes the pump contacts when
it receives a call for heat. Once the call for heat is satis ed,

The Boiler Pump terminals (TB5 - max 7.4 FLA) are fed by
120V (violet wire) internally from the main power feed. The
System and DHW contacts are dry contacts. Appropriate
voltage must be supplied to the System and DHW pumps for
proper operation.
The System pump connections are located on terminal block
5 (TB5) in the control panel. The System pump contacts are
