Tab 5.3 Burner operating parameters
Please note
Modication of these parameters should only be carried out by authorised or factory service.
Incorrect parameters may cause damage to the appliance and, in extreme cases, re and risk
to human life.
SIGN PARAMETERS RANGE UM
t1 Air ow temperature detected by NTC 100 probe (P3) - READING ONLY 0...99 °C
SP Maximum burner power setting . 0%=rL; 100%=rH 0...99 %
Y2 Offset value from rL during ignition phase - blower speed is rL+Y2 (0%=rL; 99%=rH) 0...99 %
YC Start of burner test phase 0...99
Yt YC phase duration 1...20 min
/P
Potentiometer presence:
/P = 0 : potentiometer not present;
burner output at set SP value
/P = 1 : external control (potentiometer, thermostat, 0-5 V signal)
Important: If the SCP674V130A1 motherboard is combined with a network slave board
(SCP674V124; SCP674V143; SCP674V202) DO NOT USE external control in J3B
0...1 -
rL
Minimum blower speed value (burner fan) = Minimum power output of burner - READ ONLY
rL is a functional value, not a safety value.
10...rH %
ro Offset value from rL during normal operation after switch-on phase (blower speed is rL+ro) - READ ONLY 0...60 %
rH
Maximum blower speed value = maximum power output of the burner - READING ONLY
rH is a functional value, not a safety value.
rL...99 %
Y3 Fan set-point for air distribution (temperature for switching fans on/off) - READING ONLY 10...80 °C
Y4
Fan switch-off delay time for air distribution after burner switch-off (post-ventilation time) - READING
ONLY
0...99 Sec
Y5 Air distribution fan on/off set-point differential - READING ONLY 3…15 °C
Y6
Set-point temperature for 2nd stage shutdown (operation at min. power) temperature detected by probe
P3 READING ONLY
0=function excluded
0...80 °C
Y7 Set-point differential Y6 temperature for 2nd stage shutdown - READING ONLY 3...15 °C
Y9
Blower type (burner fan): maximum speed and number of blower notches - READ ONLY
