economizer function and a discharge air sensor input. For more advanced applications, an economizer control logic has
been integrated onto the thermostat for use with proportional damper economizer actuators.
Thermostats equipped with an occupancy sensor cover provide advanced active occupancy logic, which will
automatically switch occupancy levels from Occupied to Unoccupied as required by local activity being present or not.
This advanced occupancy functionality provides advantageous energy savings during occupied hours without
sacrificing occupant comfort. All thermostats are PIR ready and can be ordered with or without Honeywell occupancy
sensor. The occupancy sensor cover is available to order separately if a PIR is needed at a later time.
FEATURES
• Available in BACnet MS/TP and ZigBee wireless protocols
• Backlit LCD display with dedicated function menu keys for simple operation
• Built in default profile set-up for easier start up and commissioning
• Fully integrated advanced occupancy functionality with a PIR accessory cover on some models
• Non-volatile EEPROM memory prevents loss of parameters during power outage
• Programmable smart fan operation can provide energy savings during night mode
• Password protection to minimize parameter tampering
• Three levels of keypad lockout to limit access to change user parameters such as setpoints, system mode,
etc.
• Gas/oil or electric system compatibility for all type of applications
• SPST auxiliary output can be used for lighting and/or economizer override
• 0 to 10 Vdc economizer output for more retrofit opportunities
— Built in dry bulb economizer logic using outdoor temperature sensor
— Input for supply/mixed air temperature sensor
• Support single and two stages heat pump with one auxiliary heat stage

INSTALLATION INSTRUCTIONS

APPLICATION
The TB7600 Series PI thermostat family is specifically
designed for single stage and multi-stage control of heating/
cooling equipment such as rooftop and self-contained units.
The TB7600 Series are communicating thermostats with
models available in BACnet
mesh protocols and can be easily integrated into a WEBs-AX
building automation system based on the NiagaraAX
platform. The product features an intuitive, menu-driven,
back-lit LCD display, which walks users through the
programming steps, making the process extremely simple.
Accurate temperature control is achieved due to the product's
PI time proportional control algorithm, which virtually
eliminates temperature offset associated with traditional,
differential-based thermostats.
Depending on the model, up to three remote sensor inputs
are available. All models contain a SPST auxiliary switch,
which can be used to control lighting or disable the

  • Page 4: Thermostat Installation

    Electronic controls are static sensitive devices. Discharge yourself properly before manipulation and installing the thermostat. Short circuit or wrong wiring may permanently damage the thermostat or the equipment. Anti-short cycling can be set to 0 minutes for equipment that has an anti-cycling timer. Do not set to 0 unless the equipment has an internal anti-cycling timer or damage to equipment can occur.

  • Page 5: Terminal Identification

    The switched leg to the input for the input to activate is terminal C (common). — The transformer of the unit provides power to the thermostat and the additional loads that will be wired to the thermostat.

    • Fan lock: Indicates that the heating and cooling action are locked out due to a defective fan operation Three status LEDs on the thermostat cover are used to indicate the status of the fan, a call for heat, or a call for cooling.

  • Page 9: User Control Options

    User options are accessed and programmed using 5 keys on the thermostat cover and are described in Table 5. The YES key is used to confirm a selection, to move onto the next menu item and to manually scroll through the displayed information.
  • Page 10 **Appears only in unoccupied mode ***Appears only in override mode There is a default profile set in the thermostat from the factory. This enables the thermostat to operate as a non- programmable unit in day mode operation at start up.
  • Page 11 Temporary setpoints can be modified through the Up arrow key ( ) and the Down arrow keys ( ). User will be prompted with the present mode (Heating or Cooling) of the thermostat and its setpoint. The Up ( ) arrow key will increment the setpoint by 0.5 degree (F or C). The Down ( ) arrow key will decrement the setpoint by 0.5 degree (F or C).

    This section describes the parameters available for TB7600 Series thermostat configuration. The TB7600 Series can be programmed at the thermostat or through WEBStation-AX, with the following exception: Wireless models must have the Com Addr, PAN ID, and Channel set at the thermostat before adding to the wireless network or doing any programming in WEBStation-AX.

To use this command, the thermostat you want to copy parameters from must be on the wireless network with a network address (Com addr) and must be the same model number as the thermostat you want to copy to.
  • Page 17 No access No access No access No access Yes access No access On initial power up of the thermostat (each time 24 Vac power supply is removed and re-applied) there is a delay before any operation is authorized (fan, cooling or heating). This can be used to sequence start up multiple units/thermostat in one location.
