SPACE HEATING

2.6.1 Overview
The HC series boiler is designed to be installed in a primary/secondary type
piping system. The boiler comes complete with a factory installed boiler pump.
The pump is designed to circulate heating system water through the boiler's heat
exchanger and primary loop piping only. The building's distribution piping system
requires a dedicated pump or pumps to provide circulation of the space heating
water through the heating system. The building pump or pumps will require a
separate control system or relays to operate the pumps.
Zoning of the space heating system can be accomplished many ways. Several
control packages are available from your local wholesaler and offer an easy
method of connecting the zoning system to the boiler. Example piping and
electrical drawing are available at www.ibcboiler.com
The boiler supplies heat to the space using an Outdoor Reset Curve. With an
outdoor sensor installed the boiler will automatically adjust its space heating
water temperature based on the parameters programmed into the boiler. See
separate publication DC / HC Controller Manual for parameter information. If
the Outdoor Sensor is not installed, the boiler will use the temperature set in the
User Set Up menu "Boiler Supply Temperature" to supply hot water to the space
heating system.
