Parameter P03; It is used to identify the burner switch ON delay in CH
mode.DuringaCHdemand,burnerisswitchedOFFwhenTowsensor
isgreaterthanTset+5ºCwhilepumpisrunning.WhenTowsensor

the parameter P03.
Parameter P04; While adjusting P4 parameter, burner power follows
trimmer P5 changes.
Parameter P05; If parameter 5 is OFF (00), CH range is normal (30ºC-
80ºC), if it is ON (01), CH range is reduced (30ºC- 50ºC), which is suit-
ableforoorheatingapplications.
Parameter P06; If parameter 6 is ON, burner is switched ON and OFF
according to set point. If parameter 6 is OFF, burner is switched ON and
OFFaccordingtoaxedsetpoint.
Parameter P07; If P07 is selected to be 00, the LED illumination is al-
ways ON. If this parameter is 01 than, the LED lights will be ON when
thereisameandifthisparameteris02,LEDisalwaysoff.
