B1HA Boiler Setup
Application Code
VD1X 1HC1T1ZP.01
This particular application represents a low mass boiler with a single system loop. Because the system flow requirements may vary, or fall outside of the parameters of the boiler flow, it is recommended to hydraulically separate the system flow from the boiler flow. This can be achieved by using a low loss header or closely spaced tees on the system loop. Upon a call for heat from an external demand such as a thermostat the boiler circulator and the system circulator will be initiated. To program the boiler for this type of application, please complete the following procedure:

B1HA Boiler Setup
In this application, you can see a Vitodens 100 paired with an indirect water heater and 2 zones. A safety device such as a thermostatic mixing valve should be added to the infloor circuit to protect the radiant heating from the higher supply water temperatures required for the air handler. This application will prioritize the DHW by diverting flow from the system to the indirect DHW using the diverting valve integrated into the boiler. To set up the boiler for this application you will need to complete the following:

B1HA Boiler Setup
Similar to the previous application, this system incorporates a Vitodens 100 Combi boiler. With on demand domestic hot water, this offers an alternative solution to installing a storage type indirect water heater. The integrated circulator and diverting valve allow the boiler to switch from heating and provide up to 3.7GPM of on-demand DHW. To set up the boiler for this application, you will need to complete the following steps:

B1HA Boiler Setup
In this system you have a Vitodens 100 with indirect water heater and a four zone system controlled via zone valves. Upon a call for heat a zone valve opens, closing the end switch on the valve, and initiates the boiler. In the event there is a call for DHW, the boilers internal pump and diverting valve, will redirect the water to the indirect water heater. This allows the boiler to commit all energy produced to the production of domestic hot water. Once satisfied, the diverting valve will return to its home position and continue supplying heat to the heating system until satisfied. To set up the boiler for this application you will need to complete the following:

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:
