![]() ![]() If you select No, continue to Step 3.4.When you see the prompt Connect RedLINK Accessories? Touch No or Yes. NOTE: If you are connecting the thermostat to the TrueZONE Wireless Adapter (THM4000), refer to the TrueZONE instructions to link the thermostat and RedLINK accessories. ![]() Used with or without the TrueZONE Wireless Adapter (THM4000)įollow prompts on the screen to select the appropriate options.Used with or without an Equipment Interface Module (THM5421).Initial setup options define the type of system you are installing: Turn on 24VAC before performing initial setup in Step 3. NOTE: If the thermostat is wired directly to the equipment, 24VAC (C wire) is required to connect RedLINK accessories. Connect gateway’s power cord to an electrical outlet that is not controlled by a wall switch.Connect RedLINK Internet Gateway to router or modem with Ethernet cable (RJ45).See Installer Setup options in Step 3.4.Ĭonnect gateway to internet and connect to power. Do NOT install a field jumper if the stage of heating has its own transformer. You must install a field jumper if the stage of heating or cooling is powered by system transformer.U1 terminals are normally open dry contacts when set up for a stage of heating or cooling.NON-POWERED HUMIDIFIER, DEHUMIDIFIER OR VENTILATOR The relay can be set to normally open or normally closed in the installer setup. Wire the thermostat U1 terminal to the low speed fan for dehumidification control at the equipment as shown. POWERED HUMIDIFIER, DEHUMIDIFIER OR VENTILATOR See THP9045 instructions for more information. Use the Kterminal in place of the Y and G terminals on conventional or heat pump systems to provide control of the fan and the compressor through a single wire-the unused wire then becomes your common wire. The THP9045A1098 C-wire adaptor is used on heat/cool systems when you only have four wires at the thermostat and you would like the thermostat to be powered with a common wire. Remove factory installed jumper for two transformer systems. Si / Si discharge a wired indoor, outdoor or discharge sensor. 51 / S1 discharge a wired indoor, outdoor or discharge sensor. Ul / Ul Relay for humidification, dehumidification ventilation, or a stage of heating/cooling. U1 / Ul Relay for humidification, dehumidification ventilation, or a stage of heating/cooling. VA Connect to Compressor Monitor, Zone Panel, Economizer Module or Lighting Panel (TOD). Backup Heat/Emergency Heat W2 Heat Stage 2 AUX-E Y Compressor Stage 1 Y Compressor Stage 1 Y2 Compressor Stage 2 Y2 Compressor Stage 2 G Fan Relay G Fan Relay A Connect to Economizer Module or Lighting Panel (TOD). W Heat Stage 1 0/B Changeover valve for heat pumps. C Common wire from secondary side of cooling transformer. Terminal Designations Terminalĭescription Terminal Description Common wire from secondary side of cooling transformer (if 2 transformers). On those models push evenly along the sides and bottom of the thermostat to connect it to the wallplate. NOTE: If your thermostat has hinges at the bottom of the wallplate as shown, insert the thermostat into the hinges, then push the top toward the wall until it snaps together. NOTE: On some models the coin cell battery compartment slides out from the left side of the thermostat when viewing it from the back (not pictured). With thermostat removed from sub-base, insert the coin cell battery. NOTE: The relay outputs and inputs on the thermostat do not function when used with an Equipment Interface Module or TrueZONE Wireless Adapter. If the thermostat is used with an Equipment Interface Module or TrueZONE Wireless Adapter, power the thermostat using Rc and C terminals or with batteries.24VAC (C wire) is required to connect RedLINK accessories. If the thermostat is wired directly to the equipment: a Refer to the table and wiring diagrams on the next page.Is the thermostat wired directly to the equipment For 24VAC primary power, connect common side of transformer to C terminal.NOTE: When the thermostat is NOT used with the Equipment Interface Module or the TrueZONE Wireless Adapter, a C wire is required for RedLINK. Insert supplied AA alkaline batteries for primary or backup power.Mount new wallplate using screws and anchors included with the thermostat. On those models pull evenly along the sides and bottom of the thermostat to separate it from the wallplate. If your thermostat has a button along the top of the wallplate, press button on top and pull to remove the wallplate as shown. NOTE: For best RedLINK performance, mount thermostats at least 2 feet apart. 13 Related Posts Reference to key features
