LED Indicators
The S9200U1000 has three LEDs. The three LEDs from
left to right as shown in Fig. 4 on page 9 are:
• Flame – Amber LED
The Amber LED Indicates flame status such as weak
or no flame. The Flame status codes are mapped in
Table 10.
• STATUS – Red LED
The Red LED indicates general system status, such as
the presence of a call for heat and various error codes.
The Status LED Status codes are mapped in Table 11
on page 20.
• E-COM – Green LED
This Green LED indicates EnviraCOM™ transmission
is underway. The LED is directly linked to communica-
tion on the EnviraCOM™ bus. The E-COM LED Status
codes are mapped in Table 12 on page 21.
— A typical transmitted message appears as a rapid
flashing of the green LED.
— A typical received message appears as single
blink, indicating the S9200U1000 has acknowl-
edged the message.
NOTE: The E-COM LED is active even if a conventional
thermostat is controlling the appliance.
Flash Code Descriptions
The LEDs will flash codes at various intervals. Each pulse
type indicates a specific functionality/ message type.
• Periodic Blink (Normal): 0.5 second on, 0.5
second off
• Pulse: A 0.25 second flash followed by 3.75
seconds of off time.
• Heartbeat: Constant 0.5 second bright, 0.5
