Crown Boiler PHNTM080 Replacement Instructions

This control is programmed for use as a replacement for the R7910B1020 control used on the following Crown boiler
models:
• This control shall be installed by a qualified service agency in accordance with these instructions.
Attempts to do so by others, or to use this control on models not listed above, could result in
unreliable operation, property damage, personal injury, or loss of life.
• As shipped, this control will not permit operation across the entire boiler input range. After the
control is installed, both the boiler model and altitude must be selected in accordance with the
instructions below. Failure to select the boiler and altitude before leaving the boiler in operation
could result in unreliable operation. Selecting an incorrect model and/or altitude could result
unreliable operation, property damage, personal injury, or loss of life.
1) Turn off all electrical power to the boiler.
2) Unplug all electrical connectors from the old control. All electrical connections to this control are
plugs (including the green screw terminal strip on the bottom of the control) and all are keyed to
prevent misconnection.
3) Press on the two tabs on the right side of the control (Figure 1) to release the old control from the
door panel.
4) Install the new control on the boiler and replace all electrical connections removed in Step 2.
5) Restore electrical power to the boiler.
6) Depending on the display software version, you should see the screen shown at the top of either
Figure 2 or Figure 3 within a few seconds of restoring power. Follow the instructions in either Step 7
or Step 8 as appropriate.
7) Boilers equipped with Version 1 display software only – The screen shown at the top of Figure 2
will appear. Do the following to select the correct model:
a) At the Home Screen on the display press MENU.
b) Press CONFIGURE from the Main Menu.
c) When prompted for a password, use the "+1" key to raise the password to "005" and press
SUBMIT, then NEXT.
d) Review the warning and press ACCEPT to continue to the Configuration Menu and press
FACTORY SET.
e) Review the warning and press ACCEPT to continue to the Restore Factory Settings Menu.
f) Press the large button (the one initially showing "WGR162=E") repeatedly to advance through
the boiler model choices. When the boiler model is shown which matches that on the rating plate,
press SET to save the size selected. This selection is accepted when the display stops blinking.
Note: Version 1 display software was only used on boilers intended for installation at altitudes
between sea level and 2000ft. There is therefore no way to select other operating altitudes using this
display.
