household system and as plumbed should typically flow through the circulating pump without the
pump running.

CONTROLLER SETUP
Red dial switch, front panel:
Non outdoor reset –simply set the “knob” to the desired outlet temperature shown here and on the front
panel decal.
This control strategy is accomplished via disconnecting the outdoor sensor and performing a power reset
to the boiler (low voltage power cycle).
Outdoor reset – the temperature decal will relate to the OT 0° set point and the “knob” numbers coincide
with the curves below. High and low mass also relate to the ramp-up water temperature starting point, as
shown. Select the high or low mass with the rate of temperature rise based on outdoor temp (OT).
Comment: The WF-ANZ* test set allows field change of the base temperature start point.
This control strategy is accomplished via connecting the outdoor sensor and performing a power cycle on
the boiler (low voltage power cycle).
The front panel temperature selection number coincides to the curves below. This temperature value
shown on the front decal is actually the supply water at 0° outside.
