NOTE: Read the entire instruction manual before starting the<br />
installation.<br />
SAFETY CONSIDERATIONS<br />
Improper installation, adjustment, alteration, service, maintenance,<br />
or use can cause fire, electrical shock, or other conditions which<br />
may cause personal injury or property damage. Consult a qualified<br />
installer, for information or assistance. The qualified installer must<br />
use factory-authorized kits or accessories when modifying this<br />
product. Refer to the individual instructions packaged with the kits<br />
or accessories when installing.<br />
Follow all safety codes and wear safety glasses. Read these<br />
instructions thoroughly and follow all warnings or cautions attached<br />
to the unit. Consult local and state building codes and Sheet<br />
Metal and Air Conditioning National Association (SMACNA) for<br />
special installation requirements.<br />
Recognize safety information. This is the safety-alert symbol .<br />
When you see this symbol on the unit or in instructions and<br />
manuals, be alert to the potential for personal injury.<br />
Understand the signal words DANGER, WARNING, and CAU-<br />
TION. These words are used with the safety-alert symbol. DAN-<br />
GER identifies the most serious hazards which will result in severe<br />
personal injury or death. WARNING signifies hazards which<br />
could result in personal injury or death. CAUTION is used to<br />
identify unsafe practices which would result in minor personal<br />
injury or product and property damage.<br />
WIRING DIAGRAM NOTES<br />
1. Refer to Fan Coil Installation Instructions for features and<br />
additional wiring information<br />
2. To activate dehumidify function on FK or FV series, remove<br />
J1 jumper at fan coil control board.<br />
3. Heat pump must have a high pressure switch for dual fuel<br />
applications.<br />
4. Refer to outdoor equipment Installation Instructions for proper<br />
setup.<br />
5. Select the ″zone″ position on the 2-speed heat pump control<br />
board. This applies only to 38YDA (R-22 units).<br />
6. As an option O/W2 can be used to allow Thermidistat to<br />
control second-stage heat. Refer to indoor unit Installation<br />
Instructions for proper setup.<br />
7. As an option, Y1/W2 can be used to allow Thermidistat to<br />
control third-stage heat. Refer to indoor unit Installation<br />
Instructions for proper setup.<br />
8. Furnace must control its own second-stage heat operation via<br />
furnace control algorithm.<br />
9. Outdoor air sensor must be attached in all dual fuel applications.<br />
10. Refer to indoor equipment Installation Instructions for proper<br />
setup.<br />

11. To activate dehumidify feature on older style variable-speed<br />
furnaces (<strong>Carrier</strong> 58MVP) that do not have a DE connection,<br />
a pilot duty 24-vac relay must be used.<br />
12. To activate dehumidify feature on current style variable-speed<br />
80 percent non-condensing furnace, disconnect green (DE-<br />
HUM) wire from G on furnace control board and connect to<br />
dehumidify terminal on Thermidistat Control.<br />
13. Dip switch No. 1 should be set in OFFposition for air<br />
conditioner installations. This is factory default.<br />
14. Dip switch No. 1 should be set in ON position for heat pump<br />
installations.<br />
15. Dip switch No. 2 should be set in OFF position for singlespeed<br />
compressor operation. This is factory default.<br />
16. Dip switch No. 2 should be set in ON position for 2-speed<br />
compressor operation.<br />
17. Configuration Option No. 10 ″Dual Fuel Selection″ must be<br />
turned ON in all dual fuel applications.<br />
18. Remove DE jumper to enable DEHUM input on furnace<br />
control board.<br />
19. No connection should be made to the furnace HUM terminal.<br />
