HIGH EFFICIENCY COMMERCIAL BOILERS AND VOLUME WATER HEATERS
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 rated for 120Vac, 7.4 Amps. To use the
contacts, power must be supplied on one terminal
with the other terminal wired to the pump or a relay
controlling the pump.
The DHW pump connections are located on terminal
block 5 (TB5) in the control panel and are rated for
120Vac, 7.4 Amps. To use the contacts, power must be
supplied on one terminal, and the other terminal wired
to the pump or a relay controlling the pump. Additional
120VAC circuits may be required for the pumps.
8.7.6 Demand Priority Confi guration
From the Demand Priority Confi guration, the installer
can adjust the priority of the different demand types.
Central Heat, Lead Lag, Domestic Hot Water
The control uses arrows as indicators to point to the
loop with higher priority.
8.7.7 Modulation Confi guration
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
satisfi ed, the pump will remain on for the defi ned pump
overrun time.
The Boiler Pump terminals (TB5 - max 7.4 FLA) are
