CONFIGURING AND STATUS DISPLAY INSTRUCTIONS Status display The Terminal Equipment Controller features a two-line, eight-character display. There is a low level backlight that is always active and can only be seen at night. When left unattended, the Terminal Equipment Controller has an auto scrolling display that shows the current status of the system. Each item is scrolled sequentially with the back light in low level mode. Pressing any key will cause the back light to come on to high level.
USER INTERFACE User configuration menu • Unoccupied mode Override An Override can be made during an unoccupied period. If the Override option is enabled in the lockout configuration pressing the Override button will resume occupied setpoints for a time specified by the parameter; “ToccTime.” • Keypad interface Override Down Up An Override can be made during an Unoccupied period.
Local keypad interface An Override can be made during an unoccupied period.

Removes the scrolling display and only presents the room temperature to the user. MenuScro Menu scroll Default: On = Scroll active With this option enabled, no status is given for occupancy and outdoor temperature.
BI1 Binary input no.1 configuration Default: None (None): No function will be associated with the input. Point can still be monitored through the BACnet ™ network. (Motion NO): Used in Occupied Mode only to toggle from the Occupied setpoints to the Stand-By setpoints when no motion is detected for 60 minutes at the zone. When motion is detected at the zone, the Occupied setpoint resumes. Contact opened = No motion detected. Contact closed = Motion detected.
RehtConf Number of Reheat Stages and their applications 0 = None Default: 1 = Modulating Duct Reheat Only RTU in cooling mode uses Control Curve 1 RTU in heating mode uses Control Curve 2 1 = Modulating Duct Reheat Only Zone will operate in VAV heating or cooling only based on the Master RTU mode without any reheat.
5 = Duct heater & On-Off/Pulsed perimeter reheat (All electric) Zone will operate in VAV heating or cooling based on the Master RTU mode and use 2 stages of local reheat. The first reheat stage will use the modulating BO5 reheat output (10s or 15m cycles) for a local modulating electric duct reheat device with a 24 Vac fired SSR.

Valid only if analog reheat sequences are enabled DA = Direct acting Reverse acting or Direct acting 0 to 100 % = 0 to 10 VDC actuator signal for Reheat 1 RA = Reverse acting 0 to 100 % - 10 to 0 VDC Analog output signals Default: DA signal AO2 OALK VZ7260F5x00B models only Outdoor air temperature value from the RTU controller under which the analog reheat stage will be allowed to be used.

St-By HT Stand-by heating setpoint Stand-by heating setpoint adjustment. This setpoint will be used if there is a motion detector connected and configured on BI1 or a PIR sensor cover used. Default: 65 °F (18°C) Heating setpoint range is: 40 to 90 °F (4.5 to 32.0 °C) St-By CL Stand-by cooling setpoint adjustment. This setpoint will be Stand-by cooling setpoint limit used if there is a motion detector connected and configured on BI1 or a PIR sensor cover used.
Pband Proportionnal band setting Default is : 3 Adjust the proportional band used by the controller PI control loop. Warning. Note that the default value of 3.0 °F (1.2 °C) gives satisfactory operation in most normal installations. cases. The use of a superior proportional band is different than the factory default is normally warranted in applications where the controller location is problematic and leads to unwanted cycling of the unit.
Min Pos Zone damper minimum position Sets the minimum position of the damper. 0 to 100% (Increments: 1% or 10%) Default : 10% Max Pos Zone damper maximum position Sets the maximum position of the damper for both heating and cooling mode of the RTU.
Not a configuration parameter. Only displays the controller’s performance in cooling mode. CL Perfo Controller’s cooling performance This value is only valid if there’s no change in system mode, setpoints or occupancy for at least 1.5 hours.
