” DHW
button.
11.8.7
Control Software Version
To view the control software version cycle the incoming power to the
CHALLENGER off then on.
The
LED will be lit for CH (central heating call)
The
LED will be lit for DHW (domestic hot water call) with optional Triangle Tube SMART/COMFORT I.F.W.H.
“X” represents temperature or pressure readings. When temperature is displayed it will be followed by “ºF” or “ºC” in the main display
and the appropriate LED will be lit. When pressure is displayed it will be followed by a “P” in the main display. Pressure can only be
read when the operating display is blank or shows a “A”.
* If factory installed CH Low Water Cut Off (LWCO) is below 7 psig [0.5 bar] the main display will flash a soft lockout of LOP (burner
and CH primary pump is blocked) followed by the pressure reading. Once CH system pressure is increased above 7 psig [0.5 bar]
normal boiler operation will be restored. Check LWCO wiring if LOP flashes to 90 _P (PSI) or 6.0 _P (bar).
** If the outdoor sensor is not installed the main display will display ODS when the boiler is in standby without a CH or DHW call for
heat or any errors. The lack of the outdoor sensor will not prevent the unit from operating on a CH or DHW call for heat, but is
recommended to increase system efficiency
