Sensor Binding
The C7089R Outdoor Sensor must be bound with the
W8735ER Wireless Outdoor Reset Module in order for
communication between the two controls to be established.
When the W8735ER Wireless Outdoor Temperature Module
is powered but not bound to a sensor, the POWER LED will be
ON (green) and the CONNECTED LED will be OFF.
1. Remove the cover from the C7089R to expose the
CONNECT button.
2. Press the CONNECT button on the W8735ER until the
CONNECTED LED flashes green (1 blink/second) after
approximately five seconds of flashing red. If the sensor
is not bound within the next 15 minutes the W8735ER
times out and the CONNECTED LED will turn OFF.
3. While the CONNECTED LED flashes green on the
W8735ER, press the CONNECT button on the C7089R
sensor.
4. The CONNECTED LED will start to blink fast (4 blinks/
second).
NOTE: If flashing doesn't speed up to 4 blinks/second,
the sensor and the W8735ER have not bound.
Repeat step 4. If binding is not successful during
a 15 minutes period, the W8735ER will time
out. Repeat steps 2 through 4. Make sure the
W8735ER and the sensor are positioned at least
3 feet apart during the binding process.
5. Once the flashing rate goes back to 1 blink/second,
press the CONNECT button on the W8735ER to end
the binding process.

6. Once the C7089R sensor and the W8735ER bind, the
CONNECTED LED on the W8735ER will be ON solid
(green).
7. Place sensor cover back on the sensor and return the
sensor to the bracket. See Fig. 3.
NOTE: Pressing the CONNECT button on either the
W8735ER or wireless sensor for 15 seconds or
more will result in the unbinding of the wireless
sensor and deactivation of the OTC functionality.
To rebind the sensor to the W8735ER follow
steps 1-7 in this section.
NOTES:
— If the W8735ER is bound to a sensor but the sen-
sor signal is lost, the CONNECTED LED will be
ON (red).
— Once the sensor is bound to the W8735ER and
the module is connected to the EnviraCOM com-
munication bus as described in the WIRING sec-
tion of this document, hold the sensor where you
intend to install it and check for the outdoor tem-
perature to be displayed on the combustion con-
trol. If the outdoor temperature is not displayed,
change the positioning of the sensor.
— If the W8735ER is not successfully bound to
C7089R within five minutes of power up, the
W8735ER will generate a missing sensor alarm.
See Table 6 for a complete listing of EnviraCOM
alarms and trobuleshooting guide.
