CONTROLLER SETUP
Front Dial
Non-Outdoor Reset – simply set the knob to the desired outlet temperature 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° F 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 reset
to 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° F outside.
