SPACE HEATING
Overview
The Combi boiler is designed to be installed in a primary/secondary type
piping system. The unit comes complete with a factory-installed pump, which is
designed to circulate heating system water through the unit’s heat exchanger and
primary loop piping only. The building’s distribution piping system may require a
dedicated pump or pumps to circulate space heating water through the heating
system. The unit can operate a separate building pump (120V 1.0 AMP max).
Zoning of the space heating system can be accomplished many ways. Several
control packages are available from your local wholesaler and o󰀨er an easy
method of connecting the zoning system to the boiler.
The unit supplies heat to the space using an outdoor reset function. With an
outdoor sensor installed, the unit automatically adjusts its space heating water
temperature based on the parameters programmed into the unit. See separate
controller manual for parameter information. If the Outdoor sensor is not installed,
the unit uses the temperature set in the “User Set Up” menu “Boiler Supply
Temperature” to supply hot water to the space heating system.
