Attached is the install manual for the ICP Observer. We have also taken some of the common question information below.

LED INDICATORS:

Under normal operation, the Yellow and Green LEDs will be on continuously (solid). If the Observer Damper Control does not receive communications with the User Interface, the Green LED will not be on. If a zone damper has been modulated to a position that is not fully open or fully closed, that zone’s LED will flash slowly, to indicate a partially open damper. If there are faults present, the Yellow LED indicator will blink a single−digit status code. It will blink at a fast rate, pause, then repeat.

TRANSFORMER REQUIREMENTS:

The Observer Zoning System requires a field supplied 75VA (maximum)  transformer to power the dampers. Use of the transformer provided in the furnace or fan coil is NOT recommended. Refer to Fig. 13 & 14 for transformer usage. Alternate Zone Panel transformer recommended @ 60VA 24V field supplied.

WIRING CONSIDERATIONS:

Ordinary thermostat wire is ideal when wiring the Observer Zoning System (shielded cable is not typically necessary). It is recommended to use 18 AWG thermostat wire to install the Observer Zoning system. For retrofit applications, 18−22 AWG may be acceptable. Wiring lengths should not exceed 100 feet. 22 AWG wire lengths should be limited to runs of 25 feet or less. A CTS Zone Sensor may replace the Zone Remote Room Sensor with no wiring changes at a later date. The Observer Wall Control requires 4 conductors, each damper actuator requires either 2 or 3 conductors. Cut off or fold back and tape any unneeded wires. Plan the routing of wiring early to avoid possible problems later.  Sometimes, it is a good idea to run conduit in hard to access locations, in case a new wire must be pulled at a later date.   Remember, all wires converge at the Observer Zoning Panel, so its location is important. NOTE: Wiring of the Observer communication bus only requires a four wire connection; however, it is good practice to run thermostat cable having more than four wires in the event of a damaged or broken wire during installation. The following color code is recommended for each Observer connection bus connection: DX+ — Green = Data + DX- — Yellow = Data C — White = 24 VAC (Com) R — Red = 24VAC (Hot) It is not mandatory that the above color code be used, but each bus connection in the system MUST be wired consistently.
