B1HA Boiler Setup
Similar to the previous application, this system utilizes circulators instead of zone
valves. Upon a call for heat, the multizone control initiates the associated circulator
and sends a signal to the boiler's. Once the boiler has received this signal, the
integrated boiler pump starts and the boiler fires. If there is a call for DHW during a
heating cycle, the boiler's integrated diverting valve will transition into DHW mode
and a new target setpoint will be established. Once the DHW tank is satisfied, the
diverting valve will switch back into heating mode and supply heat to the low loss
header. To set up the boiler for this application you will need to complete the following:
