  • Page 4: Introduction

    During power loss its internal memory saves settings for unlimited time, and the clock continues to run for at least 24 hours. An extension of Bryant’s proven line of thermostats; it provides separate setpoints for heating and cooling.

  • Page 5: Installation Considerations

    INSTALLATION CONSIDERATIONS Power This control is powered by 24VAC only. It requires 24VAC (Rh and/or Rc and C terminals) of the low- voltage transformer to be connected to it for proper operation. It will not operate without these 2 connections. Rh and Rc are connected via PCB breakout jumper.
  • Page 6 Fig. 1 - PCB Breakout Jumper Models There are programmable and non- programmable models for all applications. They can be configured for AC or HP installations, allowing it to be used in place of all Bryant thermostats. Programmable thermostats configured non- programmable if user desires.
  • Page 7 Remote Indoor Temperature Sensor A remote temperature sensor may be used with the programmable heat pump and programmable air conditioner thermostats where it is desirable to install the thermostat in a limited access location while measuring the temperature in the living space.

  • Page 27 WHILE IN CONFIGURATION MODE The option number is displayed in the heat setpoint location and the configuration setting is displayed in the cool setpoint location. On the T6- PAC01- A/PHP01- A (programmable) models, a box will surround the option number. The mode button is used to move the box between the two displayed values.
  • Page 28 Defaults HP model defaults to HP. AC model defaults to AC. Option 02 — Clean Filter Timer Select hours of blower operation (heating, cooling, or fan) before CHECK FILTER icon is displayed. With OF selected, icon will never come on, disabling this feature. Time selection can range from 800 to 7200 hr by selecting numbers 1 through 9.
  • Page 29 SRTN Sensor 1 Sensor 2 Sensor 3 Sensor 4 A09130 Fig. 17 - Remote Room Sensor - Parallel Wiring This selection determines which sensor the control will use for measuring room air temperature. Room air temperature can be sensed in one of three ways; the local sensor (L) located on the Display Module, the remote room air sensor (r), or the average of local and remote sensors (Lr).
  • Page 30 Option 07 — Zoning This selection should be set to On when the thermostat is to be used as part of a zoning system. It is assumed that the zoning equipment will take care of time guard and cycle timers. The minimum on time is still controlled by the thermostat. Default is OF (off).
  • Page 31 Option 11 — Deadband Setting Between Heat & Cool This option is not available on Heat Only and Cool Only systems. This selection is to allow the installer to choose how much differential exists between the heating and cooling setpoints. Allowable selections are 1- 6. Default is 2.
  • Page 32 Option 16 — Maximum Cycles Per Hour This selection limits the number of cycles per hour that the thermostat allows the system to operate. Selections are 2, 4, 6. 2 — The heating and cooling outputs will be energized no more than 2 times per hour.
  • Page 33 Option 19 — Dry Contact Configuration (programmable models only) There are 2 available selections, OF and 1. OF — The dry contact is always de- energized. 1 — The dry contact will be energized for the specified number of minutes per hour.
  • Page 34 When the keypad lock selection is turned on, the padlock icon will be displayed. To unlock the keypad, press and hold the UP/DOWN buttons simultaneously for five seconds. When the keypad is unlocked, the padlock icon will turn off. The keypad will remain unlocked for two minutes after the last button press.
  • Page 35 Option 22 — High Cool Latch Temperature (only available if outdoor sensor is present) An outdoor sensor is required for high cool latch feature. This selection is only available when Option 1 is set to H2, A2, or h2 and when Option 7 (zoning) is set to OF (off).
  • Page 36 On — The Y1 and Y/Y2 outputs are simultaneously energized to satisfy all heating demands. Default is OF (off). Option 24 — Programmable/Non- Programmable This selection allows the installer to configure the thermostat as either programmable or non- programmable. Selections are P, nP. Default is P (programmable models only).
  • Page 37 Option 28 — UV Light Reminder This selection allows the installer to select the number of months after which the UV Light icon will be displayed to indicate to the homeowner that it is time to call the dealer to have the UV Lights replaced. Selections available are OF (off), 6, 12, 18, 24, 30, 36, 42, 48.
  • Page 38 Option 31 — Daylight Savings Time Configuration (programmable models only) This selection allows the installer to set the thermostat to automatically change by one hour on the specified day, month, and week specified. OF (off) — Daylight Savings Time Function disabled. 1,2 On —...
  • Page 39 Option 33 — Single or Two- Piece Installation This configuration allows the thermostat to compensate for the amount of heat generated by the thermostat electronics to allow more accurate sensing of the temperature sensor. The amount of heat compensation will be different between single installation and two- piece installation.
  • Page 40 If the outdoor air temperature is below 12_F/- 11_C and there is sufficient demand for the equipment to be on, then the fan output is turned back on and the W/W1 output is energized. In a two speed unit the Y/Y2 output should be energized in addition to the W/W1 output.

  • Page 41: System Start- Up And Checkout

    SYSTEM START- UP AND CHECKOUT The AC/HP Control is designed with a built- in installer test capability. It allows easy operation of equipment without delays or setpoint adjustments to force heating or cooling. To enable installer test mode, press and hold the fan button for 15 seconds.
  • Page 42 Final Settings Be sure to press DONE to exit installer setup mode. If the system is to be left in operation after installation is complete, use MODE button to select between HEAT, COOL, or AUTO to provide desired operation of heating, cooling, or auto. On the programmable models, the default setpoints and programmed schedule conform to the Energy Starr requirements of the U.S.
  • Page 43 Setting The Clock, Calendar, Daily Schedule, and Vacation Settings (programmable models only) To set the clock, press the SET button once. The Clock will be displayed at the bottom center of the screen. Use the soft keys to move the box around the digits to be set and the UP/DOWN buttons to change the setting.

  • Page 44: Operational Information

    Vacation Setpoints A special set of temperature setpoints exist which are active in vacation mode. They are adjustable by the homeowner, are exclusively for vacation mode, and are remembered from one vacation selection to the next. See Table 2 for default values. Table 2 –...
  • Page 45 temperature error is greater than 5_ (usually due to a large change in desired temperature) and equipment stages up in 60 second intervals. The ten- minute staging timer does not require the thermostat to change to a higher stage after 10 minutes. If the system is able to meet the demand (maintain setpoint) it may not change stages after the 10 minute timer has expired.
  • Page 46 Equipment On Indicators When cooling equipment is on, a COOL ON icon is displayed. While cooling equipment operation is delayed by the timeguard or cycle timer, COOL ON will flash. The same is true for HEAT ON. During second stage compressor operation a “2” will be displayed with the HEAT ON or COOL ON icon.
  • Page 47 used to operate a ventilator, damper, system blower, or other auxiliary device. There are two terminals, D1 and D2. If it is desired to operate a ventilator or other device, the D1 and D2 terminals can be connected directly to the equipment. This will provide a closed contact for the specified number of minutes per hour.

  • Page 48: Troubleshooting

    TROUBLESHOOTING If the display module doesn’t power up after power is applied, check the Rc/Rh and C terminals for 24VAC. If 24VAC is present, check the voltage between Vg and V+. This voltage will be approximately 12- 20VDC. If voltage is present, check the polarity to make sure it is wired correctly.
  • Page 49 Table 3 can be used as a troubleshooting tool for determining which outputs will be active for a particular configuration and each operating mode. When replacing a failed component such as an equipment control module or a display module, the installer should replace both parts as a matched set. It is very easy to accidentally mix an A/C or HP display with a PAC equipment control module.
