Power 4 Fan 1 Speed
FAN1 speed at power 4:
Defines the FAN1 speed at power 4 (depends on the selected fan
mode - open loop, closed speed loop or closed pressure loop).
NOTE: Not used when advanced regulation is selected.
28
Power 5 Fan1 Speed
FAN1 speed at power 5:
Normal regulation
– defines the FAN1 speed at power 5 (depends
on the selected fan mode – open loop, closed speed loop or
closed pressure loop).
Advanced regulation
– defines the MAXIMUM allowed FAN1
speed for the PID regulator. Controller calculates the FAN1 speed
for each power PID regulator output. Maximum number of steps
is 1024.
Fan 2
FAN2 can be used:
- as ambient air fan (
FAN2 for Room Heating
option), usually used with stoves and other air to air heat
exchanger devices
- as chimney fan performing flue gas suction functions (
FAN2 As Chimney
fan
option), usually used in
burner applications where FAN1 is used as combustion fan, blowing air into the burning chamber, while
FAN2 is sucking out of the burning chamber
- for keeping constant underpressure in the burning chamber (
FAN2 As Chimney Fan + FAN2 Pressure
Close Loop
option)
29
Test Fire Fan 2 Speed
FAN2 speed in Test Fire sequence
NOTE: If the flue gases temperature is below PAR58 [⁰C] in FAN2
for Room Heating mode, FAN2 is switched off.
30
Stop Fire Fan 2 Speed
FAN2 speed in Stop Fire sequence:
NOTE: If the flue gases temperature is below PAR58 in
FAN2AsAmbient mode, FAN2 is switched off.
31
Heat Up Fan 2 Speed
FAN2 speed in Heat Up sequence
NOTE: If the flue gases temperature is below PAR58 in FAN2 for
Room Heating mode, FAN2 is switched off.
32
Fuel Ignition Fan 2 Speed
FAN2 speed in Fuel Ignition sequence
NOTE: If the flue gases temperature is below PAR58 [⁰C] in FAN2
for Room Heating mode, FAN2 is switched off.
33
Ignition Test Fan 2 Speed
FAN2 speed in Ignition Test sequence
NOTE: If the flue gases temperature is below PAR58 [⁰C] in FAN2
for Room Heating mode, FAN2 is switched off.
34
Power 1 Fan 2 Speed
FAN2 speed at power 1:
Normal regulation
– defines the FAN2 speed at power 1
(depends on the selected fan mode – Fan 2 for Room Heating,
Fan 2 As Chimney, or Fan 2 As Chimney used in closed pressure
loop).
Advanced regulation
– defines the MINIMUM allowed FAN2
speed for the PID regulator. Controller calculates the FAN2 speed
