ALTERNATE PIPING AND WIRING CONNECTION
Not all existing systems may be 100% compatible with our PB150 boiler so an
alternate method of connections can be used. These installation options should be
discussed with your hydronic installation specialist to insure proper operation.
Primary and secondary loops
A primary loop of reasonable size of at least 1-¼” pipe from the supply to the return
can be installed. The circulator pump can be wired into the R terminal on the aquastat
allowing for constant operation. Zones are now connected to draw from the primary
loop.
Thermostat Control
The yellow wires that are normally connected to a thermostat can be wired together
bypassing the thermostat. The aquastat will now control water temperature based on
the low limit settings. When the water reaches the low limit temperature the aquastat
will shut down the burner to pilot mode until the water temperature drops below the
low limit setting minus the differential setting. If the low limit setting is 170° F and
the differential is 25° F, this means the burner will fire at the high rate until the water
temperature reaches 170° F and then put the burner into pilot mode until the water
temperature drops to 145° F.
Dump Zones
Be sure to incorporate a dump zone into the system. The dump zone can be controlled
by using a strap on aquastat connected to the supply piping above the boiler.
Lockout Control
When connecting in series or parallel with an existing system, an interrupt to the call
for heat may be needed to prevent both boilers from firing. A normally closed 120° F
snap switch can be installed on the smoke box of the PB150 boiler and wired into the
thermostat circuit of the existing boiler preventing the existing boiler from firing while
the PB150 boiler is in operation. Be sure that when the PB150 boiler is not being used
to shut off its power via the service switch.
