5.D Suggested Boiler Piping Schematics (continued)
NOTE: Domestic circulator MUST be sized for
both the indirect and the boiler.
Figure 11. Single Boiler, Variable Primary Space Heating with Parallel Piping for indirect Tank
Control:
• Use outdoor reset to maintain building loop temperature. See
Section 8.C.3 on page 67.
• Set System pump to AUTO, pump runs during space heating
when outdoor temperature is below warm weather shutdown.
• Place jumper on T-T for constant heating call; or interrupted if
so desired.
• System and DHW pumps all controlled by The Touchscreen
Control. Boiler pump not used.
• Pump operation congurable in pump conguration menu.
See Section 8.D.5 on page 83
• Use DHW sensor, terminals 39 and 40, or aquastat,
terminals 53 and 54.
• System Pump must be OFF during DHW operation for
DHW priority.
BMS control:
• For Modbus/BACnet BMS mapping, refer to Section 7.F on
page 44
• Enable/disable boiler via T-T terminals (49, 50) for space
heating.
• To enable/disable boiler for DHW using an aquastat, use
terminals 53 and 54.
• To enable/disable boiler for DHW using a sensor, use
terminals 39 and 40.
• BMS can control ring rate or setpoint via terminals 55 and
56. (analog input).
• System, boiler and DHW pumps controlled by BMS or The
Touchscreen Control.

representation of a piping style and is
not intended to be used as a working
