COMMERCIAL THERMOSTAT (P/N TSTATBBPCM01-B)

IMPORTANT: Read entire instructions before programming the thermostat.

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, ventilation, and air conditioning) system. Separate heating and cooling set points and auto-changeover capabil- ity allow occupied and unoccupied programming schedules for energy savings.

All thermostats allow up to 4 time and 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 pro- grams for an unlimited time.

OPERATION

I. THERMOSTAT DISPLAY

The thermostat display is located in the top center of the thermostat. See Fig. 1. The following information can be dis- played on the screen:

•mode (OFF, EHEAT, COOL, AUTO, or HEAT)

•fan setting (ON or AUTO)

•hold status

•room temperature

•desired temperature

•clean filter status

•time of day

•day of the week

•schedule period (OC1, UN1, OC2, or UN2)

•outdoor temperature (optional)

II.THERMOSTAT PROGRAMMING BUTTONS AND OPERATION

The thermostat has programming buttons which are used to change the set points of the thermostat, set the modes, and program schedules. The programming buttons are accessible from underneath the thermostat cover. To access the pro- gramming buttons, pull on the hinged thermostat cover. See Fig. 2. The programming buttons are: Copy Previous Day, Program, Mode, Change Day, End, Fan, Set Time/Temp, Occupied, and Hold.

The Up and Down buttons are used to change the current, desired temperature set point and to scroll through program- ming set points. The Up and Down buttons are accessible from the outside of the thermostat.

The daily schedule can be overridden in 3 ways: pressing the Hold button, pressing the Up and Down buttons to change the temperature set point, or pressing the Occupied button.

A. Programming Button Lockout

The thermostat has a lockout feature which will not acknowledge programming 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 buttons for 2 minutes. The lockout feature is configured by the installer.

NOTE: The lockout code sequence is Mode, Copy Previous Day, Set Time/Temp, and Hold.

NOTE: The Occupied button is not disabled by the Lockout feature.

B. Hold Button Operation

Pressing the Hold button disables the time and temperature schedule and holds the current desired temperature set point. When a Hold is active, the HOLD annunciator is dis- played on the thermostat screen. To release the Hold, press the Hold button a second time. The Hold will remain active indefinitely and the desired temperature will not change according to the program time or the derived temperature values. The desired temperature can be changed using the Up and Down buttons.

C. Fan Button Operation

The Fan button selects fan operation. When the fan is set to ON, the fan will run continuously. When the fan is set to AUTO, the fan will run during heating and cooling operation only.

If the fan is set to ON, but the Allow Continuous Fan During Unoccupied Hours configuration is set to OF, the fan will not run during unoccupied hours when heating or cooling is not active. A small triangle will be displayed next to the Fan On icon to show the user that the fan is not running because of the unoccupied time period.

D. Mode Button Operation

The Mode button selects the operating mode of the thermo- stat. If OFF is selected, the thermostat will not enter Heat- ing or Cooling mode. If HEAT is selected, the thermostat will only enter Heating mode (if the room temperature is below the heating set point). If COOL is selected, the thermostat will only enter Cooling mode (if the room temperature is above the cooling set point). If AUTO is selected, the thermo- stat will enter Heating or Cooling mode based on the room temperature and the heating and cooling set points. Units also have an EHEAT selection which is configured by the installer. If EHEAT is selected, the unit will use the second stage of heating to provide heating, if necessary. The annun- ciator for each selection will be displayed on the thermostat when selected.
