DANGER identifies the most serious hazards which will re­sult in severe personal injury or death. WARNING signifies a hazard which could result in personal injury or death. CAU­TION is used to identify unsafe practices which would result in minor personal injury or property damage.
GENERAL
Bryant’s 7-day, commercial, programmable thermostats are wall-mounted, low-voltage thermostats which maintain room temperature by controlling the operation of an HVAC (heat­ing, cooling and ventilation) system. Separate heating and cooling set points and auto-changeover capability allow occu­pied and unoccupied programming for energy savings.
All thermostats allow up to 4 time/temperature settings to be programmed per 24-hr period. Each thermostat stores pro­grams for 7 independent days. Batteries are not required. Dur­ing power interruption the internal memory stores comfort schedules for an unlimited time while the clock continues to run for at least 72 hours.
The thermostat can be configured to accept several different equipment configurations, from single-stage heating and cool­ing to 3 stages of heating and 2 stages of cooling. The ther­mostat comes factory configured for 1 stage of cooling and 1 stage of heating.
INSTALLATION
I. THERMOSTAT LOCATION
The thermostat should be mounted:
• approximately 5 ft from the floor
• close to or in a frequently used room, preferably on an in-
side partitioning wall
• on a section of wall without pipes or ductwork The thermostat should not be mounted:
• close to a window, on an outside wall, or next to a door
leading to the outside
• where exposed to direct light and heat from a lamp, the
sun, a fireplace, or any other temperature-radiating object which may cause a false reading
• close to or in direct airflow from supply registers or return
air grilles
• in areas with poor air circulation (such as behind a door or
in an alcove)
II. SET DIP SWITCHES
There are 4 small switches on the back of the circuit board which must be configured by the installer. The ON position is indicated by small letters on the switch. Ignore the num­bers (1-4) on theswitch.Theswitchdesignation(A-D)isprinted on a sticker next to the switch. To change a switch position, use the corner of a small screwdriver to slide the switch ON or OFF. Set the DIP switches before installing the thermostat.
A. Air Conditioner or Heat Pump Selection (Switch A)
Use switchAto select between air conditioning and heat pump applications.A heat pump application uses a reversing valve. Set switch A to OFF for air conditioning applications (no re­versing valve). Set switch A to ON for heat pump applica­tions (O is used to energize the reversing valve). The factory setting is OFF.
B. Compressor Stage Selection (Switch B)
Switch B is used to select between a single-stage and a 2-stage compressor. Set switch B to OFF for a single-stage compres­sor.Set switch B to ON for a 2-stage compressor. The factory setting is OFF.
C. Outdoor Air or Remote Room Sensor (Switch C)
Switch C is used to configure the thermostat to work with either a outdoor air sensor or a remote room sensor. The sen­sor for the application must be connected to terminals S1 and S2 of the thermostat. Set switch C to OFF for a outdoor air sensor.Set switch C to ON for a remote room sensor.The fac­tory setting is OFF.
D. Averaging of Sensors (Switch D)
Switch D isusedif a remote room sensor is being used (switch C set to ON). The remote room sensor reading can be averaged with the sensor reading of the thermostat. Set switch D to OFF if averaging is not required. To average the readings of the thermostat and remote room sensors, set switch D to ON. The factory setting is OFF.
III. INSTALL THERMOSTAT
WARNING:
power to the unit. There may be more than one power disconnect. Electrical shock can cause injury or death.
1. Turn off all power to unit.
2. If an existing thermostat is being replaced: a. Remove existing thermostat from the wall. b. Disconnect wires from existing thermostat. Do not
allow wires to fall back into the wall. As each wire is disconnected, record wire color and terminal connection.
c. Discard or recycle old thermostat.
NOTE: Mercury is a hazardous waste and must be disposed of properly.
Before installing thermostat, turn off all
3. Open thermostat rear door (mounting base) to expose mounting holes.
4. Route thermostat wires through large hole in mount­ing base. Remove outer sheath from wires for added flexibility.
5. Level mounting baseagainstwall and mark wall through the 2 mounting holes in base.

6. Drill two
CAUTION:
⁄16-in. mounting holes in wall where marked.
Be careful not to drill into wiring in wall.
Electrical shock could result.
7. Secure mounting base to wall with 2 screws and an­chors provided. Ensure all wires exit through hole in mounting base.
8. Adjust wire length and routing to allow proper closure of the thermostat. Strip each wire at the end no more
1
⁄4-in. to prevent adjacent wires from shorting to-
than gether. Match and connect wires to terminals on the thermostat. See Fig. 1-4.
CAUTION:
Improper wiring or installation maycause damage to the thermostat. Check to ensure wiring is correct before proceeding with installation of unit.
9. Push excess wiring into wall. Seal hole in wall to pre­vent drafts.
10. Close thermostat door.
11. Turn on power to unit. The thermostat will receive power from the unit.
On power up the thermostat display shows the selected setup mode (AC - single-stage air-conditioner,HP - single-stage heat pump, A2 - 2-stage air conditioner, H2 - 2-stage heat pump) for a few seconds, depending on DIP switch settings.
IV. SET THERMOSTAT CONFIGURATION
Configuration options, like DIP switch settings, are intended to be selected at installation and are not normally modified by the user. These options are not discussed in the owner’s manual and must be done as part of the installation. A spe­cial procedure for the thermostat allows entry into the con­figuration mode. To enter configuration mode, press and hold the fan button for approximately 10 seconds. The room tem­perature display will disappear and dashes (--) will be dis­played on the thermostat screen. The thermostat will auto­matically exit configuration mode if no button is pressed for 10 seconds. Seven different configurations can be set in con­figuration mode.
A. Fahrenheit or Celsius Selection
The thermostat can be set to use a Celsius or Fahrenheit tem­perature display. Press the Change Day button in configura­tion mode to access the parameter. Use the Up and Down buttons on the thermostat to change the setting between F (Fahrenheit) and C (Celsius). The default value is F.
B. Fan ON or OFF When Heat is Energized Selection
The thermostat can be set to turn the fan (G output) on or off when the heat input (terminal W) is energized. Press the Hold button while in configuration mode to access the parameter. Use the Up and Down buttons to toggle between OF (fan off during heating) and ON (fan on during heating). The default value is OF.
C. High Ambient Electric Heat Lockout Selection
If DIP switch Ais set to ON (heat pump application) and DIP switch C is set to OFF (an outdoor temperature sensor is
present), electric heat can be locked out if the outdoor ambi­ent temperature rises above the user-defined value. Tempera­tures of 15 to 55 F (in 5-degree increments) can be selected. The lockout can also be disabled. The default is OF (dis­abled). Emergency heat mode disables this function. Press the Copy Previous Day button in the configuration mode to ac­cess the parameter. Use the Up and Down buttons to in­crease or decrease the setting.
D. Clean Filter Timer Selection
The clean filter selection determines how many hours of blower operation will pass before the Clean Filter message is dis­played.A timer in the thermostat accumulates the total blower operation hours. The range of values is 400 to 3600 hours (in 400-hour increments).
• a ‘‘1’’ will be displayed for 400 hours of operation
• a ‘‘2’’ will be displayed for 800 hours of operation
• a ‘‘3’’ will be displayed for 1200 hours of operation
• a ‘‘4’’ will be displayed for 1600 hours of operation
• a ‘‘5’’ will be displayed for 2000 hours of operation
• a ‘‘6’’ will be displayed for 2400 hours of operation
• a ‘‘7’’ will be displayed for 2800 hours of operation
• a ‘‘8’’ will be displayed for 3200 hours of operation
• a ‘‘9’’ will be displayed for 3600 hours of operation The selection can also be set to OF (disabled). Press the
Reset Filter button in the configuration mode to access the parameter. Use the Up and Down buttons to change the set­ting. The default is 2 (800 hours).
NOTE: During the selection procedure, the Clean Filter mes­sage will be displayed, even if OF (disabled) is chosen.
E. Anticipator Adjustment Selection
The anticipator adjustment controls the sensitivity and cycle rate of the thermostat. Higher numbers decrease the sensi­tivity and slow the cycle rate. Lower numbers increase sen­sitivity and speed up the cycle rate. A limiting feature of the thermostat will not allow more than 4 equipment cycles per hour, regardless of the anticipator setting. Values can range from 1 to 9. The default is 3. The default selection will pro­vide optimum performance in nearly all installations. Do not change the setting unless there is a need to do so. Press the Mode button during configuration mode to change the set­ting. Use the Up and Down buttons to increase or decrease the value.
Unlike conventional thermostat anticipators, the setting is not determined by current draw. There is no need to mea­sure, know, or compensate for the current. There is no need to ‘‘droop’’ with this thermostat, regardless of the anticipator setting.
F. Keypad Lockout Selection
The thermostat has a lockout feature which will not acknowl­edge configuration buttons until the lockout code is entered. After the lockout code has been entered, the keypad will re­main unlocked until the user has stopped pressing keys for 2 minutes. The Lockout selection can be set to ON or OF (dis­abled). Press the Set Timekeyinconfigurationmodetochange the setting. Use the Up or Down buttons to toggle between off and on. The default is OF.
NOTE: If the lockout function is enabled, the user can only disable the lockout by pressing the correct buttons, in order, within a 10-second time period. The button sequence is: press the Mode button; press the Copy Previous Day button; press the Set Time button; and press the Hold button. The lockout will then be disabled until the user stops pressing buttons for 2 minutes.
