S9200U1000 UNIVERSAL HOT SURFACE IGNITION INTEGRATED FURNACE CONTROL
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 Off 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 S1 DIP switch settings.
The default factory settings are all OFF and are shown in
bold.
Table 10. DIP Switch (S2) Settings - Safety Timings.
DIP Switch S2 Descriptions
HSI Igniter Warm-up Time = 17/27
Trial For Ignition = 4 seconds:
– Ignition Activation Period = 1 second
– Flame Recognition Period = 3 seconds
This is the default setting.
HSI Igniter Warm-up Time = 17/27
Trial For Ignition = 6 seconds:
– Ignition Activation Period = 3 seconds
– Flame Recognition Period = 3 seconds
HSI Igniter Warm-up Time = 30/30 seconds
Trial For Ignition = 6 seconds:
– Ignition Activation Period = 3 seconds
– Flame Recognition Period = 3 seconds
HSI Igniter Warm-up Time = 30/30 seconds
Trial For Ignition = 8 seconds:
– Ignition Activation Period = 5 seconds
– Flame Recognition Period = 3 seconds

The shorter of the two periods listed (17 seconds)
applies to the first trial only, while the longer period
(27 seconds) applies to the subsequent trials during the
same call for heat.

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 thermostat,
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 registra-
tion on the EnviraCOM™ Bus.
3. Fan timing changes may be detected when two
appliances are Twinned.
