SAFETY TIMINGS, FIELD
SETTINGS, AND FIXED
PARAMETERS
WARNING
Fire or Explosion Hazard.
Can cause severe injury, property damage, or
death.
Field Settings and Safety timings must comply
with OEM specifications. Do not extend Safety
timings beyond those recommended. Failure to
follow recommended safety timings may result
in equipment damage, bodily injury, or death!
IMPORTANT
Extending the Safety timing beyond that rec-
ommended by the appliance OEM may result
in unburned gas accumulation in the appli-
ance which can cause an explosion!
Safety Timing Lockout Jumper
The S9200U1000 is equipped with a Safety Timing
Lockout Jumper intended to make safety timings
permanent once they are selected. To insure that
resetting the Safety Timing DIP switches (Table 10 on
page 12) can not cause a hazardous condition,
remove the Safety Timing Lockout Jumper once the
Safety Timing DIP switch position selection is made.
In case the S9200U1000 Safety Timing Lockout
Jumper (see Table 7) is not removed after the DIP
switch selection is made, the DIP switch settings will
be permanently stored in the control's non-volatile
memory after the 10th full cycle each time the DIP
switch is set. Once permanently stored, the Safety
Timings can not be changed.
See See “DIP Switch S2 - Safety Timings” on page 12.
.
Field Settings
The field settings can be changed whenever
necessary. The change takes effect for the next
situations which are being influenced by that change.
If for example a particular delay is in progress and
settings are changed, the current delay setting is not
influenced by that change. The field settings are not
considered safety critical therefore, changes to these
parameters can be made at any time during and after
installation.
See “DIP Switch S1 - Field Settings” on this page.
Fixed Parameters
Fixed parameters are those settings which may not be
adjusted at any time.
Table 8 describes the S9200U1000 Fixed parameters.
DIP Switch (S1 and S2) settings
The following field and safety parameters may be set
using DIP switches S1 and S2. Refer to Fig. 4 on
page 9 for the location of the two DIP switch blocks.
DIP Switch S1 - Field Settings
Table 9 and Fig. 6 describe the S1 DIP switch settings.
The default factory settings are all OFF and are shown
in bold.

settings; all OFF.
COOL FAN OFF DELAY TIMING
The Cool Fan Off Delay is the time period after the call
for cooling has ended and before the deactivation of
the blower motor at the cool speed. The timing is
