INSTALLATION INSTRUCTIONS
TB7600 Series
Thermostat
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® MS/TP and ZigBee® wireless 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
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.

TB7600 SERIES COMMUNICATING RTU/HEAT PUMP THERMOSTATS
•Remote indoor averaging sensing with 2, 3, 4, 9 or 16 sensors
•Remote discharge air sensor input
•Automatic frost protection to prevents costly freeze damage
•Anti short cycle and minimum on/off run time protection to reduce wear and maximizes life span of mechanical equipment
•Two programmable digital inputs for added flexibility can be use to monitor filter status, activate a remote temporary occupancy switch, and/or used as a general purpose service indicator
•7 day programmable models, 2 or 4 events for use in non-networked applications*
•Six hour reserve prevents the need to reprogram day/time on programmable models after a power outage
Heat Pump Model Specific Features
•Selectable single or dual stage compressor stages
•High balance point locks out auxiliary heating when outside air temperature is above set value, low balance point locks out heat pump compressor operation when outside air temperature is below the set value
•Comfort/economy mode maximizes heat pump use before turning on auxiliary heating
•Compressor/auxiliary interlock adds flexibility by locking out heat pump operation during auxiliary heating to prevent high pressure trip when the coil is downstream of the auxiliary heat source
*Use programmable models only when installing as standalone thermostats that may eventually be added to a WEBsAX network. When a programmable thermostat is added to a network, schedules should be applied through the WEB- Station-AX.

1Use programmable models only when installing as standalone thermostats that may eventually be added to a WEBsAX network. When a programmable thermostat is added to a network, schedules should be applied through the WEB- Station-AX.
2Thermostats ordered without an occupancy sensor cover can be retrofitted with an occupancy sensor cover later if needed.
More Information
We recommend downloading the appropriate integration reference document (wireless or BACnet) and if installing thermostats with occupancy sensor covers, then also downloading the PIR Application Guide before you begin installation. All documentation is available on http://customer.honeywell.com.
—BACnet Integration Manual for TB7600 Series Thermostats (Form No. 63-4523)
—Wireless Installation & Integration Reference Guide for TB7200, TB7300, and TB7600 Thermostats (Form No. 63-4522)

Theory of Operation
The TB7600 uses a proprietary adaptive logic algorithm to control the space temperature. This algorithm controls the heating/air conditioning system to minimize overshoot while still providing comfort. It provides exceptional accuracy due to its unique PI time proportioning control algorithm, which virtually eliminates temperature offset associated with traditional, differential-based on/off thermostats.

CAUTION
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.
All TB7600 Series thermostats are to be used only as operating controls. Whenever a control failure could lead to personal injury and/or loss of property, it becomes the responsibility of the user to add safety devices and/ or alarm system to protect against such catastrophic failures.

NOTES:
—If auxiliary output is used to toggle occupancy of the electronic control card inside the equipment, configure the relay parameter (Aux cont) to the N.O. setting. A second relay can be added for additional functionality of the occupancy output.
—If the same power source is used for the heating stages, install jumper across RC and RH. Maximum current is 2.0 amps.
—Economizer output uses a half bridge rectifier. Reference of the control signal is the common of the power supply of the thermostat (terminal C).
—Electromechanical contacts are to be used with the digital inputs. Electronic triacs cannot be used as mean of switching for the input. 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.

TB7600 SERIES COMMUNICATING RTU/HEAT PUMP THERMOSTATS
THERMOSTAT USER INTERFACE
The thermostat features a two-line, eight-character display. There is a low-level backlit level that is always active and can only be seen at night. To turn on the back light to high level, press any key on the front panel. The back lit display will return to low level when the thermostat is left unattended for 45 seconds.
When left unattended, the thermostat has an auto scrolling display that shows the actual status of the system. Use the MenuScro in the configuration menu to lockout the scrolling display and to only present the room temperature and conditional outdoor temperature to the user. With this option enabled, no local status is given on the system mode or occupancy.
Each item is scrolled one by one with the back lighting in low level mode. Pressing any key will cause the back light to come on to high level. When left unattended for 10 seconds after changes are made, the display will resume automatic status display scrolling.

Manual scroll of each menu item is achieved by pressing the Yes (scroll) key repetitively. The last item viewed will be shown on the display for 30 seconds before returning to automatic scrolling. Temperature is automatically updated when scrolling is held.
Outdoor air temperature display is only enabled when outdoor air temperature sensor is connected.
• A maximum range status display of 122 F (50 C) indicates a shorted sensor. Associated functions, such as mode lockouts and economizer function are automatically disabled.
• A minimum range status -40 F (-40 C) is not displayed and indicates a opened sensor or a sensor not connected. Associated functions, such as mode lockouts and economizer function are automatically disabled.
If alarms are detected, they will automatically be displayed at the end of the status display scroll. During an alarm message display, the back lit screen will light up at the same time as the message and shut off during the rest of the status display. Two alarms maximum can appear at any given time. The priority for the alarms is as follows:
•Frost ON: Indicates that the heating is energized by the low limit frost protection room temperature setpoint 42 F (5.6 C)
•SetClock: Indicates that the clock needs to be reset. There has been a power failure which has lasted longer than 6 hours
•Service: Indicates that there is a service alarm as per one of the programmable digital input (DI1 or DI2)
•Filter: Indicates that the filters are dirty as per one of the programmable digital input (DI1 or DI2)
•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. See Table 4 for more details.

User Control Options
The TB7600 Series thermostat features an intuitive, menu-driven, back-lit LCD display that walks users through the programming steps, making the programming process extremely simple. This menu is typically accessed by the user to modify system setting such as temperature or system mode, fan mode, etc.
It is possible to bring up the user menu at any time by pressing the MENU key. The status display automatically resumes after exiting the user-programming menu.
If the user pauses at any given time during programming, Auto Help text is displayed to help and guide the user through the usage and programming of the thermostat. When left unattended for 45 seconds, the display will resume automatic status display scrolling.
User options are accessed and programmed using 5 keys on the thermostat cover and are described in Table 5.
Table 5. User Control with Thermostat Keys
The YES key is used to confirm a selection, to move onto the next menu item and to manually scroll M16911 through the displayed information.

The MENU key is used to access the Main User Menu or exit the menu.
