CONFIGURABLE BI/UI INPUTS OVERVIEW Binary input #1 can be configured for the following functions: 1. (None): No function will be associated with the input 2. (Rem NSB): remote NSB timer clock input. The scheduling will now be set as per the binary input. It provides low cost setback operation via a dry contact Contact opened = Occupied Contact closed = Unoccupied 3. (Motion NO) and (Motion NC): Advanced PIR occupancy functions using a normally open (NO) or normally closed (NC) remote PIR motion sensor.
Contact closed = Alarm displayed 5. (Service): a backlit flashing Service alarm will be displayed on the Terminal Equipment Controller LCD screen when the input is energized. It can be tied in to the AC unit control card, which provides an alarm in case of malfunction. Contact opened = No alarm Contact closed = Alarm displayed Universal input #3 can be configured for the following functions: 1. (None): No function will be associated with the input 2. (COC/NH) Change over dry contact.

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 lighting in low level mode. Pressing any key will cause the back light to come on to high level.
Three status LED’s on the Terminal Equipment Controller cover are used to indicate the status of the fan (any speed), a call for heat, or a call for cooling. Fan coil models When the fan is ON, the FAN LED will illuminate When heating & reheat is ON, the HEAT LED will illuminate When cooling is ON, the COOL LED will illuminate USER INTERFACE Unoccupied mode override An Override can be made on commercial models during an unoccupied period.
Local keypad interface Each of the sections in the menu is accessed and configured using 5 keys on the Terminal Equipment Controller cover. Is used to toggle between the different system modes available as per sequence and menu selected. Repetitively pressing the button will toggle between all the available modes. Available menus are dependent on selected sequence of operation.
Single occupied setpoints adjustment (Local occupied setpoint adjustment when “Stp Func” = Attch Stp ) AUTO MODE COOLING MODE HEATING MODE OFF MODE Cool XX.X °F or °C Heat XX.X °F or °C No access to setpoint Setpoint presented to user is the setpoint from the last action taken by the Terminal Equipment Controller or the one currently in use.

CONFIGURATION PARAMETERS DEFAULT VALUE PswrdSet Configuration parameters menu access password Default value = 0 Range is: 0 to 1000 SIGNIFICANCE AND ADJUSTMENTS This parameter sets a password access to prevent unauthorized access to the configuration menu parameters. A default value of “0” will not prompt a password or lock the access to the configuration menu.
BI 2 Binary input no.2 configuration (None): No function will be associated with the input (Door Dry) Door contact & Motion detector: This Default value = None configuration is only functional if binary input #1 is set to Motion NO or Motion NC or a PIR accessory cover is used. With this sequence enabled, the occupancy is now dictated through those 2 inputs. Any motion detected will set the zone to occupied status.
UI3 Universal input no.3 configuration Default value = None (None): No function will be associated with the input (COC/NH) Change over dry contact. Normally Heat: Used for hot / cold water or air change over switching in 2 pipe systems. Contact closed = Cold water or air present Contact opened = Hot water or air present Only used and valid if system is setup as 2 pipes. Parameter (Pipe No) set as 2 pipes. (COC/NC) Change over dry contact.
Lockout Keypad lockout levels Default value = 0 No lock USER KEY FUNCTIONS LEVEL 0 1 2 3 4 5 SeqOpera Sequence of operation Selects the initial sequence of operation required by the installation type and the application Default is: Sequence #1 SEQUENCE OF OPERATION SYSTEM = 2 PIPES SYSTEM = 4 PIPES 0 = Cooling Only Off - Cool 0 = Cooling Only 1 = Heating Only Off - Heat 1 = Heating Only 2 = Cooling With Electric Reheat 3 = Heating With Electric Reheat Off – Auto – Heat – Cool 2 = Cooling With
St-By TM Stand-by Timer value Default = 0.5 hours Time delay between the moment when the PIR sensor detected the last movement in the area and the time when the Terminal Equipment Controller stand-by mode and setpoints become active. Range is: 0.5 to 24.0 hours in 0.5hr increments Unocc TM Unoccupied Timer value Default = 0.
Cool min Minimum occupied & unoccupied cooling setpoint Minimum cooling setpoint limit adjustment. Default value = 54 °F ( 12 °C ) Cooling setpoint range is: 54 to 100 °F ( 12.0 to 37.5 °C ) Pband Proportional band setting Default = 3 Adjust the proportional band used by the Terminal Equipment Controller PI control loop. Note that the default value of 3.0 °F ( 1.2 °C ) gives satisfactory operation in most normal installation cases.
Set Type Temporary setpoint enable Default is : Permnent Enables temporary setpoints feature to any change of occupied or unoccupied setpoint. Temporar: (temporary) Local changes to the heating or cooling setpoints by the user are temporary. They will remain effective for the duration specified by “ToccTime”. Setpoints will then revert back to their default value after internal timer “ToccTime” expires. To change setpoints permanently, revert this variable to No or write setpoints through the network.
aux cont Auxiliary contact function & configuration Default value = 0 Not Used 0 Aux contact function used for reheat IF SEQUENCE IS SET TO REHEAT THROUGH NETWORK OR LOCAL, Ignore this parameter.
Med AO2 Default value: 6.0 V The middle speed AO2 fan output value when the fan is enabled. This value is used only if the fan mode is set to Med. 4.1 to 7.0 V High AO2 The maximum AO2 fan output value when the fan is enabled. Default value: 8.6 V This value is used if the fan mode is set to High and as a maximum output if the fan output is set to auto. 7.1 to 10.0 V UI3 dis Used as diagnostic / service help to troubleshoot and diagnose Display UI3 value.
