To install the thermostat controller:1. Use a Phillips-head screwdriver to remove thesecurity screw on the bottom of the thermostatcontroller cover.Note: Normally, the security screw is packagedseparately in a plastic bag with the thermostatcontroller. Skip this step if the screw is not installedon the bottom of the cover.2. Pull the bottom edge of the thermostat controllercover and open the thermostat controller asillustrated in Figure 1.FIG:cvr_rmvl4. Pull approximately 6 in. (152 mm) of wire from thewall and insert the wire through the hole in thethermostat controller mounting base.5. Align the thermostat controller mounting base onthe wall and use the base as a template to markthe two mounting hole locations.6. Position the thermostat controller mounting baseso that the arrow on the base points upward toindicate the top of the thermostat controller.Note: If you need to install the thermostat on anelectrical junction box, use 2-1/2 x 4 in.(63 x 101 mm) square boxes with mud ring covers,and avoid smaller 1-1/2 x 4 in. (38 x 101 mm) or3 x 2 in. (76 x 51 mm) square boxes. Thisprocedure ensures that you have enough space forcabling and end-of-line devices, if needed.Note: For surface-mount applications, usedurable mounting hardware such as Molly boltanchors that cannot be easily pulled out of themounting surface.7. Secure the mounting base to the wall surface usingtwo mounting screws as illustrated in Figure 3.Note: Be careful not to overtighten the mountingscrews.Figure 1: Removing the Thermostat ControllerCover3. Carefully pull the locking tabs on the right side ofthe thermostat controller mounting base andunlock the Printed Circuit Board (PCB). Open thePCB to the left as illustrated in Figure 2.FIG:mnt_bsPCBLockingTabsFIG:op_circ_bdFigure 3: Securing the Thermostat ControllerMounting Base to the Wall8.

9. Remove the screw terminal blocks that areattached to a disposable adhesive. Figure 4illustrates the locations of the screw terminalblocks on the thermostat controller.!!CAUTION: Risk of Electric Shock.Disconnect the power supply beforemaking electrical connections to avoidelectric shock.CAUTION: Risk of Property Damage.Do not apply power to the system beforechecking all wiring connections. Shortcircuited or improperly connected wiresmay result in permanent damage to theequipment.Figure 4: Removing the Screw Terminal BlocksWiringWhen an existing thermostat controller is replaced,remove and label the wires to identify the terminalfunctions. When a TEC22x7-4 Series ThermostatController is replaced, simply remove the old screwterminal blocks and reinsert them onto the PCB of thereplacement thermostat controller.The LONWORKS connection does not have a removableterminal block. It has two screw terminals, one for eachof the wires.To replace a thermostat controller:1. Unscrew both LONWORKS terminal screws andremove the wires.2. Replace the thermostat controller.3. Reinsert the LONWORKS wires.4. Tighten the LONWORKS terminal screws, as shownin Figure 5.FIG:trmnl_blcksIMPORTANT: Make all wiring connections inaccordance with local, national, and regionalregulations. Do not exceed the electrical ratings ofthe TEC22x7-4 Series Thermostat Controller.To wire the thermostat controller:1. Strip the ends of each wire 1/4 in. (6 mm) andconnect them to the appropriate screw terminals asindicated in Table 1 and Figure 6 throughFigure 19.Note: For more details on wiring the LonWorksnetwork, refer to the LONWORKS Network LayoutTechnical Bulletin (LIT-1162150).2. Carefully push any excess wire back into the wall.Note: Seal the hole in the wall with fireproofmaterial to prevent drafts from affecting theambient temperature readings.3. Reinsert the screw terminal blocks onto the PCB.4. Reattach the LONWORKS communication wires tothe terminal block. See Figure 5.Note: If inserting multiple wires in the terminals,be sure to properly twist wires together prior toinserting them in the terminal connectors.5. Reattach the thermostat controller cover to themounting base (top side first).6. Use a Phillips-head screwdriver to reinstall thesecurity screw on the bottom of the thermostatcontroller cover.TEC22x7-4 Series LONWORKS® Network Thermostat Controllers with Two Outputs Installation Instructions 3

For more details on wiring theLONWORKS network, refer to the LONWORKS NetworkLayout Technical Bulletin (LIT-1162150).To connect the thermostat controller to the LONWORKSnetwork:1. Connect the LONWORKS network wires to theLONWORKS network terminal block on thethermostat controller (Figure 5).Note: There is no polarity when connecting theLONWORKS network wires to the thermostatcontroller; however, we recommend keeping thepolarity consistent throughout the network.2. After the LONWORKS network wires are connectedto the first thermostat controller, continue in adaisy-chained fashion to the next device.Note: The LONWORKS network wiring mustcomprise twisted-pair lines.Do not run the LONWORKS network wiring in the sameconduit as line voltage wiring (higher than 30 VAC) orother wiring that switches power to highly inductiveloads (such as contactors, coils, motors, orgenerators).Figure 5: LON Terminal Wiring ConnectionThe LONWORKS network requires proper terminationand biasing at the end of a segment (a segment is aphysically continuous length of wire). The thermostatcontroller is not equipped with the ability to provide thistermination; therefore, it cannot be located at thephysical end of a LONWORKS network segment unlessa terminator is attached.
