Metasys Network Sales Resource Manual 635Application Specific Controllers SectionProduct BulletinIssue Date 0601TEC1100 Series ThermostatsTEC1100 is a series of non-programmablethermostats with a Liquid Crystal Display (LCD)and a keypad for easy menu selection. TheMetasys® N2 Bus provides the programmabilityfor the most efficient space control. The user caneasily adjust heating or cooling setpoints, view theroom or outside air temperatures, or selectcontinuous fan operation and mode of operation(Day/Night).The TEC1100 series includes three models:Single-stage (TEC1101), Heat Pump (TEC1102),and Multistage (TEC1103). It can be used withfurnace, heat pump, packaged air conditioningunit, and rooftop unit applications. Fuzzy logicalgorithms have been incorporated to provideprecise setpoint control.Figure 1: TEC1100 Series ThermostatsFeatures and Benefits❑ Metasys N2 OpenCommunication❑ Liquid Crystal Display(LCD)❑ Pushbutton Selection❑ Low Profile Design❑ Temperature Alarm❑ °C or °F Selection❑ Sensor CalibrationProvides compatibility with a provencommunication network; N2 Bus is widelyaccepted by Heating, Ventilating, and AirConditioning (HVAC) control suppliersProvides real time control of the environmentfrom an easy-to-read displayAllows for easy adjustment of the thermostat’smany optionsFits with any decor; enhanced with a uniquecover designAlerts the user when the room temperature ismore than 1°C (1°F) away from the setpointafter 45 minutes of operation.Allows the user to select Celsius or Fahrenheitdisplays by pressing the Up/Down arrowbuttons without affecting the Metasys displayAllows for easy calibration by pressing theFan button for ten seconds and using theUp/Down arrows to adjust the sensors© 2001 Johnson Controls, Inc. 1Code No. LIT-635110www.johnsoncontrols.com

P roduct OverviewThe TEC1100 series is based on the establishedT500 product. The three TEC1100 models aresimilar to the T500 models: HCN, HPN, and MSN.These models support most common HVACapplications. The TEC1100 provides theadvantage of Metasys N2 Networkcommunication, so the user can view operation ormake adjustments in the space or from a remoteworkstation. Additionally, a subtle cover designchange provides a distinctive appearance, whichis unique to Johnson Controls. The cover islockable to minimize access to setpoint buttons.A dditional FeaturesThe TECs also offer many additional features:• Adjustable Temperature RangeProvides the user with selection of comforttemperatures from 16 to 32°C (60 to 100°F).• Light-Emitting Diode (LED) Indicators/Alarms(TEC1102 and TEC1103)Up to three LEDs indicate system activity orproblems, including fan proof or filter change.The center LED (TEC1102 only) representsauxiliary heat (E Ht).• DIP Switch SelectionsUsed to select a variety of options includingtwo or four minute minimum On times,keyboard lock, staged heating, LED operation,and a plenum switch to delay fan operation.• Network AddressingIndividual TEC1100 address identification canbe set at the TEC1100 using the Fan andMode buttons.• Recovery from Power FailureIn the event of a power failure, the TEC1100retains all setpoints. If the TEC1100 is in theNight mode upon power loss, the unit revertsto Day mode upon power return.• Remote SensingThe TEC1100 is compatible with theSEN-500-1 remote sensor. When you use aremote sensor, the TEC1100 internal sensor isdisabled. If you use two to six remote sensors,then all remote sensors are used fortemperature averaging.• Temporary Occupied ModeWhen the unit is in the Night mode and thekeyboard is locked, pushing the Day/Nightbutton causes the equipment to operate in theDay mode for one hour.• External TimeclocksThe TEC1100 has terminals (CLK1-CLK2) forexternal clock/timers when occupied modeinformation is not used from the network.• Remote AccessThe user reads and adjusts TEC1100parameters from an Operator Workstation orthrough the N2 Dialer Module (NDM). Binaryinputs or the temperature alarm causes theNDM to connect to the workstation uponChange-of-State (COS).• Control AlgorithmsThe TEC1100 uses fuzzy logic algorithms tomonitor the changes in room temperature andrun equipment more efficiently. Additionally,these algorithms provide appropriate control ofstaged heating and cooling to minimize cyclingof equipment.2 Application Specific Controllers—TEC1100 Series Thermostats Product Bulletin

P erson-Machine Interface (PMI)The TEC1100 has six function buttons(seeTable 2) and an LCD. See Table 1 and Figure 2for an explanation of the LCD symbols.Table 1: TEC1100 Display DescriptionsModeOFFandDescriptionThe sun and moon symbols indicate unitis either in occupied (day) orunoccupied (night) mode.Fan symbol displays when fan isoperating.Cooling symbol flickers when unit isheating.

Table 2: TEC1100 Button FunctionsButtonUp/Down Arrows∧ ∨ModeFanOutdoorDay/NightOperationAdjust setpoint values when pressed with Mode button. Toggle between units(Degrees C or F) if both are pressed together.Selects mode of operation: Heating, Cooling, Auto, Off, or Emergency(Auxiliary) Heat (display reads E ht when in this mode; available on TEC1102Heat Pump model only). Using the Up/Down arrows in mode selects setpointsfor each mode.Runs fan continuously. If Fan is not selected, fan operates intermittently tosatisfy a call for heating or cooling. Pressing Fan and Mode buttons togetherdisplays N2 address on screen.Displays outdoor temperature (optional). Read from the network or from aremote sensor. A blank (----) display indicates the optional sensor is notconnected.Alternates between day and night setpoints. Controlled from the network or anexternal time clock. Selects one hour override when the keyboard is lockedand the TEC is not in Day mode.Table 3: LED Functions (TEC1102 Heat Pump and TEC1103 Multistage Only)LED PositionFunctionRightCenterLeftNote:Indicates a fault; maintenance required. Controlled by external switch onLED 2, which displays a wrench icon and reports Change-of-State (COS) tothe Metasys system, causing the (NDM) to dial out.Indicates when highest stage heat is activated. Internally controlled. No COS.(TEC1102 heat pump only).Indicates that the filter needs changing. Controlled by external switch onLED 1, which displays the filter icon and reports a COS to the Metasyssystem, causing the NDM to dial out.Right and left LEDs are binary inputs that can be used for varied applications.4 Application Specific Controllers—TEC1100 Series Thermostats Product Bulletin
