INTRODUCTION  
Bryant’s Legacyt Series programmable thermostats are 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. A variety of features are provided including battery operation, separate  
heating and cooling setpoints, auto changeover, keypad lockout, backlighting, and  
built-in installer test. Programming features include 7 -day (all days the same) and  
5
/2 (Mon -Fri and Sat-Sun) with 2 or 4 periods per day.  
This Installation Instruction covers installation, configuration, and start -up of all  
four versions of the Legacy Series line of thermostats. For operational details,  
consult the Owner’s Manual for the specific thermostat you are installing.

href="
INSTALLATION CONSIDERATIONS  
Models  
There are four models in the Legacy Series: programmable and non -programmable, AC  
and HP. Models T2 -PAC and T2 -NAC are designed for AC systems, controlling one  
stage of cooling and one stage of heating. They will not operate a heat pump. Models  
T2 -PHP and T2 -NHP are designed for HP systems, controlling two stages of cooling  
and three stages of heating. They can be converted to AC operation. Select the  
appropriate model for the intended application.  
Power  
All Legacy Series models are dual powered. They can operate from batteries or  
2
4VAC power. Operation from 24VAC is preferred if available. Battery operation is  
used when there are not enough wires to support 24VAC operation or when  
armchair programming” is desired. For an AC system, up to six wires are needed  
for 24VAC operation and one less wire for battery operation. For a HP system, up to  
seven wires are needed for 24VAC operation and and one less wire is sufficient for  
battery operation. For heat only operation with batteries, only two wires are  
required. When battery operation is used, the C terminal does not need to be  
connected.  
Provision is also made for separate heating and cooling transformers via separable Rc  
and Rh terminals which are connected via factory -installed jumper wire.

ON = G energized with W.  
This selection determines whether the fan (G) is to be ON or OFF when the W  
(
furnace or strip heat) is ON. Furnaces and fan coils which manage their own  
blowers do not require a separate G signal. Some auxiliary heaters require a  
separate G signal to operate the blower when W is applied.  
Option 07 - Zoning  
Selections:  
OF = non -zoned system — This is default.  
ON = zoned system.  
ON disables thermostat’s internal timers which are not needed with zoning system  
controls. Must be set to OF for non -zoned systems.  
Option 10 - Reversing valve  
This selection is only available on heat pump systems. “O” terminal can be  
configured to be energized in either heating mode or in cooling mode, depending  
on heat pump operation. “O” is used to describe a heat pump system that energizes  
its reversing valve in cooling. “B” is used to describe a heat pump system that  
energizes its reversing valve in heating.

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. More specifically, press and hold the  
FAN for about 15 seconds until the display reads In on the left and St on the right  
for the programmable model, or InS in the smaller display for the  
non -programmable model. The MODE will be OFF. The MODE key (upper left)  
can now be used to select heat, cool, or emergency heat, if this is a HP thermostat.  
Selecting one of the available modes will immediately command the equipment to  
turn on in that mode. It will run for 3 minutes and then return the mode to off. With  
HP thermostats (having 2 stages of heating), the test will run for 3 minutes on each  
stage. If the thermostat is programmable, the clock display counts down from 180  
seconds while each stage operates. Changing the mode to OFF will terminate any  
running test immediately.  
During any test, the display icons will be displayed the same as for normal  
operation of that stage, as follows:  
SELECTED MODE  
DISPLAY ICONS  
off  
off  
cool  
cool on  
heat  
heat on, aux heat on  
aux heat on  
Em Heat  
To terminate the Installer Test mode press the DONE or FAN button. If the  
thermostat is left in Installer Test mode, it will revert back to normal operation after  
1
5 minutes.

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. See Owner’s Manual for details.  
Clock (programmable models only)  
Without batteries the clock will continue to operate for 8 hours while power is  
removed. With batteries, the clock operates until the end of the battery life.  
Batteries  
Battery operation is available for installations where there is no common (C) wire  
available at the thermostat or where operation is to continue while the thermostat is  
removed from the wall, usually to facilitate remote (armchair) programming. For  
battery operation, install two alkaline AA batteries. The thermostat is designed to  
operate up to one year on a set of batteries. A battery indicator on the display warns  
when battery replacement is needed. See Homeowners Guide for details. If batteries  
are installed and the thermostat is operated from 24VAC power, battery operation  
will occur only when 24VAC power is not present. The changeover between  
2
4VAC power and battery power is automatic.  
Display Lighting  
The display has two levels of lighting, high level and low level. High level lighting  
comes on for 10 seconds when the door is opened and/or buttons are being pressed  
with 24VAC and with batteries. Low level lighting is only available if the  
thermostat is operated from 24VAC. It is not available with batteries. The low level  
can be selected (see Option 18) for continuous backlight.

href="
Door Switch  
When the door is opened, the display changes from its normal operation view.  
The  
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. Mounting hole  
locations for the non -programmable are spaced to fit a horizontal junction box.

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. The Rh  
terminal powers the W output. The Rc terminal powers the Y1, Y/Y2, G and O  
outputs.  
Wiring  
For all wiring applications, use 22 AWG or larger wire. Continuous wire lengths  
over 100 ft. (30.5 m) should use 20 AWG or larger. Wire lengths are not to exceed  
2
50 ft. (76 m) per run.  
O/B Terminal -- On HP Thermostat Only  
This terminal is normally connected to the reversing valve of the heat pump. It is  
called O when the valve is energized in cooling and B when it is energized in  
heating. Option 10 of the Configuration Options makes the O/B selection.  
Timers  
There are several timers which influence the thermostat’s operation:  
If any of the timers listed below is preventing the equipment from turning on, the  
display icons which show the equipment is operating will be flashing to indicate a  
turn -on delay is present.  
Five-Minute Compressor Timeguard  
This timer prevents the compressor from starting unless it has been off for 5  
minutes. It can be defeated for one cycle by simultaneously pressing the FAN and  
UP keys.

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. This much time must elapse from the start of one cycle before another  
cycle can start. It serves to impose the cycles per hour limits. It can be defeated for  
one cycle by simultaneously pressing the FAN and UP keys.  
Auto Changeover Timer  
To prevent unnecessary cycling between heating and cooling modes, this timer  
prevents a changeover to the opposite mode until a demand exists in the opposite  
mode for 20 minutes. It is defeated when setpoints are changed so that the opposite  
mode is immediately available if desired.  
Error Codes  
Two error messages indicate problems with the thermostat’s operation. If the room  
temperature sensor fails, the temperature display will show - -, two dashes. If there  
is an internal memory failure, the temperature display will show E4. The remedy for  
each of these is to replace the thermostat.  
Table 1 shows the thermostat outputs for each available stage of heating or cooling.  
It may be useful in checkout or troubleshooting.
