S9200U1000 UNIVERSAL HOT SURFACE IGNITION INTEGRATED FURNACE CONTROL

factory-set to zero (0) seconds. To change it, first
disconnect the power, then set SW1 on DIP switch S1
according to Table 9 on page 11.
HEAT FAN ON DELAY TIMING
The Heat Fan On Delay is the period between entering
the Trial for Ignition period and the activation of the
blower motor at the heat speed (if the Trial for Ignition
is successful). The default factory setting is 30
seconds. To change it, first disconnect the power, then
set SW2 on DIP switch S1 according to Table 9 on
page 11.
HEAT FAN OFF DELAY TIMING
The Heat Fan Off Delay is the period between the loss
of supervised main burner flame after the call for heat
has ended and the deactivation of the blower motor at
the low heat speed. The timing is factory-set to 120
seconds. To change it, first disconnect the power, then
set SW3 and SW4 on DIP switch S1 according to
Table 9 on page 11.
DIP Switch S2 - Safety Timings
Table 10 and Fig. 7 describe the S2 DIP switch
settings. The default factory settings are all OFF and
are shown in bold.

THERMOSTAT TYPE
The S9200U1000 will accept either a conventional 24
Vac, 1-Stage Heat, 1-Stage Cool thermostat or the
VisionPRO or FocusPRO EnviraCOM™ enabled
thermostats.
NOTE: When using a conventional 24 Vac thermo-
stat, set the Heat Anticipator to 0.1 A.
TWINNING
EnviraCOM™ communication between two
S9200U1000 controls permits the controls' use in
Twinning applications. When a second S9200U1000
is sensed on the EnviraCOM™ Bus, each S9200U1000
control proceeds into Twinning Mode. If one of the two
S9200U1000 controls is removed from a Twinning
application, the remaining control reverts back to
standard operation only after power to the control is
cycled.
For twinning applications, Honeywell recommends
that DIP switch S1 be set to the same positions on
each device so that the heat/cool fan on/off delay
times are equal for both devices. Otherwise, the
shorter Fan On delay and the longer Fan Off Delay
times are used for both devices.
See Fig. 8 for typical wiring connections.
IMPORTANT
1. For Twinning applications, two S9200U1000
controls must be used.
2. Always power down appliances when wiring
the controls in Twinning applications. Failure
to do so may result in delays in the control's
registration on the EnviraCOM™ Bus.
3. Fan timing changes may be detected when
two appliances are Twinned.
