Notes/Comments
If zoning with pumps is your thing, then consider this application for your next install. 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. Once the boiler detects a drop in temperature
at the low loss header, it is taken out of standby mode until the call for heat is satisfied. This is a very simple
control solution for single temperature applications. To setup this boiler for this application you will need to
complete the following:
