Fig. 11 − Power−Up Display
Select the proper option for the Master Observer Wall Control.
The Master control should be selected as Thermostat. If the
Observer wall control is to be used as a zone sensor, select the
second option, Zone Sensor.
If the Observer Wall Control is already installed in an application,
the zoning panel, sensors, and dampers may be added at a later
date. The Observer Wall Control must have software version 3.0
or later installed for it to communicate with the zoning panel and
sensors.
NOTE: If the number of zones selected Is less than 6, the
remaining zones will be disabled.
After selecting Thermostat on the Observer Wall Control, it will
search for communicating indoor equipment. If a communicating
unit is found, it will proceed to search for a communicating
outdoor unit, then the zoning panel and remote sensors.

DAMPER
IMPORTANT! If using other manufacturers’ dampers, verify
damper opening/closing time requirements. Possible system
high temperature limit trips if not set according to specifications
on the motor drive requirements.
In addition, a second 60VA 24V field supplied communication
bus transformer is recommended if CTS zone sensors are used.
Refer to Fig. 13 and Fig. 14 for transformer usage.
The Damper screen allows the selection of either wire (spring
open/spring closed) or 3 wire (power open/power closed) type. If
a power open/spring closed-type damper is to be used, connect
the damper wires to the Open and Common terminals on the
Observer Zoning Panel. If a power closed/spring open-type
damper is to be used, connect the damper wires to the Close
and Common terminals on the Observer Zoning Panel.
NOTE: See the Observer Communicating Control specification
sheet for information on damper characteristics required for
compatibility with the Observer zoning system.
