BOILER MODEL
Check the
boiler model
against the model listed on
the boiler’s rating plate. Change the selection to the
correct model if not. Also verify the model number
on the WM97+ control display at power-up. Failure
to correct could result in severe personal injury,
death or substantial property damage.
HIGH ALTITUDE
If the boiler is installed at an altitude above
5,500 feet, select YES for high altitude. The WM97+
control will automatically adjust firing rates (blower
speeds) to compensate for altitude.
HIGH LIMIT TEMPERATURE
The boiler’s high limit temperature during normal
operation is fixed at 200°F and cannot be changed.
The HIGH LIMIT TEMPERATURE setting in the
WM97+ control menu is a temporary setting for
test purposes ONLY.
1. If boiler outlet water temperature exceeds this temperature,
the WM97+ control will shut down the boiler and enter lock-
out. Manual reset is required to restart the boiler.
2. The HIGH LIMIT TEMPERATURE setting will automatically
return to 200°F if power is turned off. The boiler will restart
when power is restored.
3. Use this control setting only to test the control’s high limit
function.
WWSD
1. WWSD stands for “warm weather shutdown.” It means the
boiler will not be allowed to fire if the outside temperature is
greater than the WWSD setting.
2. When the boiler is kept off because the outside temperature
is above WWSD, the graphic display will show “WWSD,” and
the boiler will remain in standby until the outside temperature
drops below WWSD temperature.
3. WWSD does not apply to DHW systems.
4. The outdoor sensor must be installed to use this function.
The
outdoor sensor must be installed unless specifically
exempted in the Energy Act statement on page 129.
ADJUST OUTDOOR
1. Use this setting to adjust the outdoor sensor temperature to
account for solar or other effects, such as long lead wire, that
would cause the sensor to read incorrectly.
