Thermostat 

Inhibited 

The thermostat connected to the expansion card is not verified.  

Enable 

The  device  waits  for  the  thermostat  signal  presence  before  burner 
ignition; in case of signal absence the burner is turned OFF until when 
a new signal is present, restart automatically. 

Air damper 

Inhibited 

The  air  valve  position  (through  the  aux.  switches)  is  not  verified  for 
purging and ignition.  

Local 

The device controls the air valve position: it opens the valve up to the 
maximum  opening  (max.  position  switch  signal)  to  start  the  purging 
time  countdown;  then  it  closes  the valve (min. position switch signal) 
in order to allow the burner ignition.  

Remote 

A remote supervisor controls the air valve position: it opens the valve 
up  to  the maximum opening (max. position switch signal) to start the 
purging time countdown; then it closes the valve (min. position switch 
signal) in order to allow the burner ignition.  

EXP Installed 

Inhibited 

The  device  doesn’t  control  any  expansion  cards  (this  setting  is 
required in case EXP-2 and EXP-4 are not installed).  

Enable 

The  device  controls  the  installed  expansion  cards  (this  setting  is 
required in case EXP-2 and EXP-4 are installed).  

Behavior/Action 

at flame loss 

Lockout 

In  case  the  signal  of  flame  presence  is  missing  for  a  time  exceeding 
the  “Reaction  time”  the  burner  is  turned  OFF  (reset  required  for 
restart).  

Recycle 

In case the signal of flame presence is missing the device executes a 
new  ignition  cycle  (included  purging).  In  case  of  proper  ignition,  at 
next  flame  presence  missing  signal  the  device  repeats  the  ignition 
cycle.  

Respark 

In case the signal of flame presence is missing the device executes a 
new  ignition  cycle  (excluded  purging).  In  case  of  proper  ignition,  at 
next  flame  presence  missing  signal  the  device  repeats  the  ignition 
cycle.  

Only one 

recycle 

In case the signal of flame presence is missing the device executes a
