SAFETY CONSIDERATIONS Read and follow manufacturer instructions carefully. Follow all local electrical codes during installation. All wiring must conform to local and national electrical codes. Improper wiring or installation may damage thermostat. Recognize safety information. This is the safety- - alert symbol . - Page 5 INTRODUCTION Bryant’s Legacyt Series programmable thermostats wall- - mounted, low- - voltage thermostats which maintain room temperature by controlling the operation of a heating and/or air conditioning system. Both heat pump and air conditioner models are available, each in programmable and non- - programmable versions.

Page 6: Installation Considerations
INSTALLATION CONSIDERATIONS Models There are four models in the Legacy Series: programmable and non- - programmable, AC and HP. Models T2- - PAC01- - A and T2- - NAC01- - A are designed for AC systems, controlling one stage of cooling and one stage of heating. They will not operate a heat pump. -
Page 7: Installation
INSTALLATION Installation Notes: The maximum wire size to be used in the installation is 22AWG (0.50mm )with 0.8mm insulation No part of the control should be installed directly outdoors or in a cabin- et outdoors The control assembly should be mounted before wires are attached Step 1 —... -
Page 8: Step 2 - Install Thermostat
Step 2 — Install Thermostat WARNING ELECTRICAL OPERATION HAZARD Failure to follow this warning could result in personal injury or death. Before installing thermostat, turn off all power to equipment. There may be more than one power disconnect. 1. Turn OFF all power to unit. 2. - Page 9 thermostat and snap apart carefully to separate mounting base from re- mainder of thermostat. 4. Route thermostat wires through large hole in mounting base. Level mounting base against wall (for aesthetic value only—thermostat need not be level for proper operation) and mark wall through four mounting holes. To avoid unin- tended bending of wall plate plastic, all four screws and anchors must be used.
- Page 10 7. Adjust length and routing of each wire to reach proper terminal and con- nector block on mounting base with 1/4- - in. (6 mm) of extra wire. Strip only 1/4 in. of insulation from each wire to prevent adjacent wires from shorting together when connected.

When power is applied, all display icons are lit for 2 seconds to test the display. Following this, the equipment type for which the thermostat is configured is displayed for an additional 2 seconds. - Page 13 and their factory default settings. Not all numbers are used in the Legacy Series because not all options are available in this series - - and numbering is consistent across the T1, T2, and T6 thermostat lines.

- Page 14 To Enter the Configuration Mode: Press and hold the FAN key for about 10 seconds until the display changes so that only two pairs of digits are showing. The left (programmable version) or the large upper (non- - programmable version) display shows the configuration number and the right (programmable version) or small lower (non- - programmable version) shows the configuration setting.
- Page 15 Option 03 - - Fahrenheit/Centigrade Selections: F = Fahrenheit — Default is Fahrenheit. C = Centigrade. Selects temperature measurement units. Option 04 - - Fan (G) ON with W output Selections: OF = G not energized with W — This is default. ON = G energized with W.
- Page 16 H — Reversing valve output (O/W2/B) is energized when HEAT mode is selected. C — Reversing valve output (O/W2/B) is energized when COOL mode is selected. Default is C. Option 11 - - Minimum Deadband Between Heating And Cooling Selections: 01 through 06 —...

- Page 18 Option 18 - - Backlight Configuration Selections: ON, OF — Default is OF. When ON is selected and the thermostat is not battery operated a low level continuous display backlight is always on. With OF selected, the backlight is only on for a short time after the door is opened or a key is pressed.

Page 20: Step 4 - Check Thermostat Operation
Step 4 — Check Thermostat Operation The Legacy Series thermostats have a built- - in installer test capability. Use it to check thermostat and equipment operation without delays or setpoint adjustments to force heating or cooling. To enter the Installer Test mode, use the same process as is used to enter Installer Configuration, only hold the FAN key longer. - Page 21 Checklist 1. Run equipment through several heating and cooling cycles to ensure proper operation. To operate the thermostat in its normal operating mode, consult the Owner’s Manual. 2. If the equipment is to be left in operation, the setpoints, operating mode, and possibly program schedule must be properly selected.

FEATURES AND ACCESSORIES Home, Away, Sleep (programmable models only) This feature provides three button selections which select from three predetermined pairs of heat and cool setpoints. In programmed versions, one of these three choices can be selected for any programmed period. To change these settings, a temperature is first selected and then the key pressed and held, similar to setting stations on a push- - button radio. - Page 23 Door Switch When the door is opened, the display changes from its normal operation view. large temperature display disappears so it will be available for other user functions. If the door is left open for 3 minutes, the display reverts to normal operation. Mounting Options For those installations requiring it, mounting hole locations for the programmable model are spaced to fit either a horizontal or vertical junction box.

Page 24: Operational And Connection Information
OPERATIONAL AND CONNECTION INFORMATION Rc/Rh Connections For installations having a separate 24VAC transformer for heating and cooling, the R connection can be separated into two connections, one for each transformer. This allows isolation between the two transformers to be preserved. To separate Rc from Rh, remove the factory supplied jumper between the Rc and Rh terminals. - Page 25 Minimum On Timer Once the equipment has been turned on, it must remain on for 3 minutes. A change in mode or setpoint will cancel this timer. Cycle Timer Based on the selection of 2, 4, or 6 cycles per hour, this timer is set to 30, 15, or 10 minutes.
