Page 6: Safety Considerations
Safety Considerations Improper installation, adjustment, alteration, service, main- tenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause death, personal injury or property damage. Consult a qualified installer, service agency or your distributor or branch for information or assist- ance. -
Page 7: Introduction
All communicating furnaces or fan coils are variable-speed and multi-stage for maximum flexibility, efficiency, and com- fort. They support controlled humidification, dehumidification, and air quality control. Either an Observer communicating, or a standard 24VAC controlled outdoor unit may be used. When using conventional, single-stage outdoor units, the... - Page 8 Observer wall control will not be negatively affected by the network-related modifications, upgrades, or similar activity of the user’s Internet service provider or mobile device carrier service.

Page 9: Quick Start
Quick Start For first time installers, Quick Start will allow a quick start up of the Observer Control before learning all the details of ® system operation. However, for the best possible comfort and operation refer to the Owner’s Manual. - Page 10 A14558 Under date, you can select the month, day, or year buttons; then use the ▲ and ▼ to select the appropriate date. . Un- der time, you can select the hour, minute, and am/pm; then use the ▲ and ▼ to select the appropriate time. You also have the option of selecting between a 12 HR or 24 HR clock format.

Page 14: Installation
NOTE: See Owners manual for further details of setting up schedules. Installation Overview This instruction covers installation of the Observer Control ® only. Physical installation instructions for the indoor and out- door equipment and accessories are provided with each unit. -
Page 15: Check Equipment
Close to or in a frequently used room, preferably on an inside partitioning wall. On a section of wall without pipes or ductwork. The Observer Control and Room Sensors SHOULD NOT be mounted: Close to a window, on an outside wall, or next to a door lead- ing to the outside. -
Page 16: Remote Room Sensors
The remote sensor can be wired to the terminal block connectors labeled S1 and S2 at the control’s back-plate. The Observer Control will automatically detect the Remote Room Sensor and ig- nore its internal temperature sensor. -
Page 17: Wiring Considerations
® NOTE: See the Observer Zone Panel Installation Instruc- tions for wiring of Observer Zoning systems. Ordinary thermostat wire is recommended. Use 22 AWG or larger for normal wiring applications. Continuous wire lengths over 25 ft. should use 18 AWG. Wire lengths over 100 ft are NOT recommended. - Page 18 9. Push any excess wire into the wall. Seal hole in wall to prevent any air leaks. Leaks can affect operation. 10. Attach Observer Control to the mounting plastic by lining up the plastic guides on the back of the control with the opening on the mounting plastic and push on.
