ATTENTION: READ THIS FIRST! Installation Guide ENV-VST-C ViewStat Color Communicating Thermostat ViewStat Color Communicating Thermostat Specifications (Cont.) Circuit Board Components: Communication and HVAC Equipment connectors Terminals with captive-wire connectors that connects to the thermostat, HVAC equipment, control system, remote sensors, and power supply. Enclosure: Material White plastic and removable front panel. Panel can be painted to match wall decor. Warning: If you paint the panel, do not paint over the exposed thermistor. Doing so can cause the external temperature sensor to work improperly. Dimensions (HWD) 5.31" x 3.93" x 1.18" (13.48 cm x 9.98 cm x 2.99 cm) Weight 5.29 oz.

FIG. 1 ENV-VST-C ViewStat Color Communicating Thermostat Overview The ViewStat Color Communicating Thermostat (FIG. 1) provides the current temperature (from an on-board sensor, a remote sensor, or an average of the on-board and remote sensors), controls and displays humidity, and displays the current outdoor temperature. The thermostat displays this information on a 3.5" (8.89 cm) color display. In addition, the thermostat provides the current day's weather forecast along with a five-day forecast, when connected to an Internet-enabled Master. The forecast information is driven from AMX's i!-Weather application. A three-year subsciption to i!-Weather is included with purchase of the thermostat. Specifications ViewStat Color Communicating Thermostat Specifications Control Voltage 24 VAC (interfaces with a power supply through the RC terminals.) Warning: Exceeding the control voltage may cause damage to the thermostat. Switched Voltage 18 – 30 VAC, 57-63 Hz Maximum Operating Current 2 amps total at rated voltage, through all outputs. 1 amps through any one output. Maximum Surge Current 2.0 A Internal Battery CR2032 for maintaining real-time clock settings during a power loss. Control Accuracy ±1.0° F (± 0.56° C) ±3% relative humidity Temperature Range Maximum displayable indoor temperature: 40° – 99° F (5° – 37° C) Maximum displayable outdoor temperature: -40° – 120° F (-40° – 49° C) Operating Range 32° – 122° F (0° – 50° C) Front Panel Components: Main LCD display 3.5" (8.89 cm) color QVGA (320 x 240) Thin Film Transistor Liquid Crystal Display (TFT-LCD). Navigation buttons The Navigation buttons are used to change various parameters on the thermostat, including the temperature setpoints. These buttons are located beneath the display. Mode/Select button The Mode/Select button is used to navigate through the various thermostat screens, including the weather screens. This button is located beneath the display. Installing a Remote Sensor Follow these steps to install the remote sensor: 1. Drill a 1/4" hole into the drywall where you want to install the sensor. 2. Fish the cable that connects to the sensor through the 1/4" hole in the wall until the edge of the sensor, where the cord meets the sensor, is flush against the wall. 3. Apply caulk, drywall putty, insulation, or any other appropriate sealant to the hole in the wall around the sensor to seal the hole. 4. Attach the connecting wires from the sensor to the S1 and S2 terminals on the thermostat. Note: You can use a maximum of 300 ft (91.44 m) of 18 AWG wire for connecting the indoor/outdoor remote sensor to the thermostat. The thermostat automatically defaults to using the on-board temperature sensor when you install it. For information about activating the remote sensor, consult the Activating the External Sensor section of the ViewStat Color Communciating Thermostat User Guide. Mounting the Base to a Wall You should only mount the thermostat onto a sheetrock wall with the anchors and screws provided with the unit. There are four screw holes located on the base of the thermostat. No tools are required to disassemble the thermostat— simply use your hands to pull the front panel off of the base. 1. Place the base over the wire hole opening in the wall. Level the base (leveling required for appearance only) and mark the screw hole mounting locations. 2. Using the supplied wall anchors, drill 1/4" hole in the center of the marked locations, and tap the wall anchors into the holes. If using the supplied screws only, drill a 3/32" hole in the center of the marked locations. Note: Minimize the wire entry hole size and seal. Drafts from inside the wall could affect temperature readings. 3. Fasten the base to the wall with the supplied screws. 4. Seal the wire entry with caulk, drywall putty, or insulation. Wiring the Thermostat Note: A qualified HVAC technician should perform these steps to ensure proper termination. 1. Make sure the HVAC system power is off. 2. Strip 1/4" (0.63 cm) of insulation from each wire you are using. 3. Secure the wires into the terminals on the base according to the appropriate wiring diagram. Use color-coding practices (i.e. white wire to W terminal) whenever possible. 4. Check each wire to ensure it is securely fastened, not broken, and any exposed wires are not touching each other. Wiring for AxLink Follow these steps to connect the wiring into a captive-wire connector: 1. Strip 1/4 inch off the wire insulation for all four wires. 2. Tin 2/3 of the exposed wire. 3. Insert each wire into the appropriate captive-wire connector up to the insulation. 4. Tighten the captive screws to secure the fit in the connector. Use 18 AWG wire to connect the AxLink wiring from the thermostat to the connector on the AxLink device as shown in FIG. 2. FIG. 2 AxLink wiring Note: The ViewStat Color Communicating Thermostat interfaces with a 24 VAC power supply from the heating/cooling unit through its RC terminal. You should not connect the power wiring from the AxLink device to the thermostat with the intent of using the AxLink device to provide power to the thermostat. The L1 terminal on the thermostat can accept the AxLink +12VDC wire and you can connect the wire to the terminal if you want to assure there are no loose wires inside the thermostat, but you should not power the thermostat by running a jumper to the RC pin. Wiring Diagrams ViewStat Color Communicating Thermostats are equipped with terminals RC, RH, C, Y, W, G, O, B, S1, S2, L1, L2, L3, and L4. You can use terminals S1 and S2 to accomodate a remote temperature sensor. Terminals L1-L4 connect to the AxLink cable. The remaining terminals are used to control various types of heating and cooling systems. You can use the thermostat with the following types of heating and cooling systems: • Single Stage Furnace and Single Stage A/C • Dual Stage Furnace and Dual Stage A/C • Roof Top Unit with Dual Stage Heat and Dual Stage Cool • Boiler with A/C with Separate Transformers • Single Stage Heat Pump • Two Stage Heat Pump • First Stage Radiant Floor Heat, Second Stage Furnace One Stage of Cooling Communication and Equipment Terminal Wiring Definitions FIG. 3 displays the terminal layout for the thermostat.

If a separate 24 VAC is not supplied to the RC terminal, you should install a jumper from RH to RC. C 24 VAC common G1 Fan on 1. If you are using a single speed fan, you should connect it to the G1 terminal. On a multi-speed fan, G1 is the lowest speed. G2 Fan on 2. On a multi-speed fan, G2 is the medium speed. G3 Fan on 3. On a multi-speed fan, G3 is the highest speed. W1 1st stage heat W2 2nd stage heat Y1 1st stage compressor Communication and Equipment Terminal Wiring Definitions (Cont.)
