  • Page 23 Storage Tank Loading System (STLS) Product Information One key aspect of the Vitodens 222-F is its unique approach to meeting varying loads of DHW demands. The Advanced Storage Tank Loading System (STLS) technology ensures a reliable and efficient DHW supply by combining storage and tankless technology. The STLS utilizes a plate heat exchanger and innovative piping strategy to combine the benefits of both a storage type water heater and on-de- mand DHW.
  • Page 24 Storage Tank Loading System (STLS)) Product Information Entering DHW Mode After the bottom 1/3 of the hot water is removed from the storage tank(1), the diverting valve switches from heating mode to DHW(2) and begins supplying heat to the plate heat exchanger(3). At the same time, the DHW pump(4) is powered and begins circulating a predefined amount of domestic water through the plate heat exchang- er(3.3gpm).
  • Page 25 Storage Tank Loading System (STLS) Product Information Large DHW Loads (>3.5 GPM) When a 222-F is required to satisfy a large dump load, the STLS has the ability to extract stored energy from the onboard tank to meet the desired load. Consider a bath tub that requires a flow rate of 4.4 GPM(1).

    Vitodens 222-F, B2TB Application 1 - Operational Setup Instructions 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 boilers recommended flow, it is beneficial to hydraulically separate the system flow, from the boiler flow.

  • Page 32 Vitodens 222-F, B2TB Application 2 - Operational Setup Instructions In this system you have a Vitodens 222-F, and a four zone single temperature system. Upon a call for heat, a zone valve opens turning on the P1(internal) & P3 circulators. In the event there is a call for DHW, the flow provided by the P1 Circulator will be diverted through the internal plate heat exchanger.

In this system you have a Vitodens 222-F, and a four zone single temperature system. Upon a call for heat from the thermostat, the associated zone pump is energized by the multi zone control.

  • Page 40 Vitodens 222-F, B2TB Application 4 Operational Setup Instructions In this application there are 2 heat circuits which operate at different temperatures. This particular drawing portrays HC1 is a low temperature circuit, and HC2 is a Mid/High temperature circuit. Although there are many different configurations, the setup below will operate HC1 as an on/off function (External Change- over) using an outdoor reset curve, and HC2 as a constant set point temperature (External Demand).

  • Page 44 Vitodens 222-F, B2TB Application 5 Operational Setup Instructions This application shows a low temperature heat circuit with 3-way mixing valve and a high temperature heat circuit piped on the system side of the low loss header. This application provides precise system temperature monitoring and increases the overall system efficiency.

  • Page 48 Vitodens 222-F, B2TB Application 6 Operational Setup Instructions This application shows 2 heat circuits with mixing valves and a high temperature heat circuit piped on the primary side of the low loss header. This system approach maximizes efficiency, control and comfort through precise water monitoring. To increase this level even further, controlling each heat circuit with a Vitotrol will allow it to feed the boiler with precise room temperature feedback.
