Zone Control Wizard Setup 1 Zone Circuit: Fixed Set Point with 157 Pump Output
Vitodens 200-W
This application shows 2 heat circuits with mixing valves, a high temperature heat circuit, and an indirect DHW on
the primary side of the low loss header. This system approach maximizes system efficiency, control and comfort
through precise water monitoring. The ZC1 thermostat call for heat will enable 157 plug to power the P3 pump
providing flow in the unmixed temperature heating circuit. The ZC1 circuit can be configured to operate based on a
Fixed Setpoint demand temperature or a Weather Compensated demand. The HC2 and HC3 mixing valve controls
will operate based on heat curve settings from within the boiler.
Select the 1 Zone Circuit with respect to the ZC
thermostat connected to the DE connections.
Press OK
This application is based on a Fixed Setpoint

a target water temperature where there is a call
for heat. You can adjust the values by arrowing
down or up to the correct set point value and
press OK.
The pump based on this application is controlled
by the 157 output. Arrow down until 157 Output
is highlighted and press OK.
