2. Install a separate circulator for each zone.

3. Connect water heater (domestic hot water) pip- ing to indirect storage water heater as shown in Section A of this manual.

The PhD Control Module turns off space heating during water heater heat- ing. The boiler circulator will turn off, preventing hot water from circulating to the system. The flow/check valve shown on the boiler outlet piping prevents grav- ity circulation in the boiler loop during water heater heating.

NOTE 1: To ensure adequate flow rate through the boiler, use the following pipe size on all boiler loop piping (connecting boiler to and from the primary/secondary connection, item 21):

-80 or -105 – 1” or larger.

-155 or -230 – 1¼” or larger. -310 – 1½” or larger.

Use at least the minimum piping size above and pipe the boiler using only pri- mary/secondary piping as shown. Failure to follow these guidelines could result in system problems.
