Brute
BOILERS AND VOLUME WATER HEATERS
8.7.4 DHW - Domestic Hot Water
Configuration
DHW - Domestic Hot Water is used to configure 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
Configuration
From this sub-menu you will be able to enable/disable
the Warm Weather Shutdown feature and adjust the set
point.
8.7.6 Demand Priority Configuration
From the Demand Priority Configuration, the installer
can adjust the priority of the different demand types.
-Central Heat
-Domestic Hot Water
-Lead Lag
The control uses arrows as indicators to point to the loop
with higher priority.
8.7.7 Modulation Configuration
From this sub-menu the installer has the ability to
adjust the range of modulation for the CH, and DHW
demands. Brute is designed with a 5:1 turn down ratio.
Any change to 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
satisfied, the pump will remain on for the defined pump
overrun time.\
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.
