INTRODUCTION
CONTROL OVERVIEW
The SYSTEMpro
™
311 is a multi-temperature reset
control that maximizes the comfort and efficiency of
a hydronic heating system. This weather-responsive
control uses outdoor reset to automatically adjust
boiler and mixed-loop water temperatures supplied
to the heating system. It can be used to supply
mixed-loop water temperature heat to a radiant
floor or snowmelt application and is specifically
created to operate efficiently as part of a Wirsbo
®
radiant/snow melt heating system. For a mixing
device, either a variable speed injection pump or
floating action mixing valve may be used. As an
added benefit, the SYSTEMpro 311 has the ability
to control an indirect Domestic Hot Water (DHW)
storage tank and a semi-automatic snow melt zone.
