• Wire stripper
• Needle nose pliers
• Measuring Tape

⚠️ CAUTION! When replacing an older thermostat that contains mercury in a sealed tube, do not discard it into the trash. Refer to thermostat-recycle.org or similar website for information on how to dispose of properly.

❗ IMPORTANT! Savant requires the use of at least one external sensor. (See Remote Sensors for options).

Remove Old Thermostat

1. Scroll through and record the current settings and schedules from the old thermostat.
2. Switch OFF power at either the breaker panel or the switch that controls the HVAC system.
3. Open the old thermostat and take a photo of the existing thermostat and wiring. The photo should reveal wire colors and terminal designations.
4. Using the top chart to the right, add a check to record which power wires are installed in the old thermostat. In addition, record the wire colors. Not all fields from the chart may be populated.
5. Remove each wire recorded and attach a label that matches the terminal designation from the old thermostat. It's important to label the wires according to the terminal designation and NOT the color of the wire.
6. Using the bottom chart to the right, add a check to record which HVAC signaling wires are installed in the old thermostat. In addition, record the wire colors.
7. Remove each wire recorded above and add a wire label to each.
8. TIP! Wrap wires around a pencil or similar to prevent the wires from falling back into the wall
9. Remove old thermostat from wall.

Two charts illustrate terminal designations and wire colors. The first chart shows terminals R, C, and RC with columns for Wire Color. The second chart shows terminals O, G, Y2, Y1, W2, and W1 with columns for Wire Color.

HELPFUL! Additional information on the terminal designators and how to wire the thermostat into different types of HVAC systems is available in the Multistat Smart Thermostat Deployment Guide (009-1959-xx) available on the Savant Customer Community.

Location and Mounting Overview

For new installations or when relocating the thermostat, follow the guidelines below:

• Locate thermostat on an inside wall away from windows and doors to reduce the exposure to drafts or direct sunlight.
• Do not locate where air circulation is poor such as in a corner or behind a door.
• Install away from any heating conditions such as near a radiator, register, vent, or fireplace.
• To adhere to ADA requirements, install thermostat 48 - 54 inches (1.22 - 1.37 meters) above the floor.
• Height requirements can be adjusted upward to 60 inches (1.5 meters) if ADA requirements are not mandatory.
• The thermostat does not need to be level to operate correctly. Leveling the thermostat is for aesthetics only.
• Thermostat can be oriented in either a portrait or landscape layout.

Install Thermostat Mounting Plate

1. Grasp the mounting plate half of thermostat in one hand, and the LCD screen half in the other.
2. TIP! Grasp the bottom of the thermostat, which is the end opposite the proximity sensor.
3. Pull the two halves apart and, at the same time, gently rock the front and back halves back and forth until they separate.
4. Position the mounting plate onto the wall. Using a pencil, mark the two mounting holes onto the wall.
5. Use the bubble level in the center of the mounting plate to level when mounting using a portrait layout.
6. When mounting using a landscape layout, remove the bubble level by pushing it out through the rear of the mounting plate and reinstall it into the bubble level slot on the right side of the center cutout.
7. With a #2 Phillips screwdriver, screw the wall anchor into the wall on each mark made. A 5/32 inch hole can be pre-drilled to make it easier when screwing the anchor to the wall. Wall anchors are not required with installs that have a sub wall to fasten to.
8. Pull the existing wires through the center cutout in the mounting plate.
9. Screw the mounting plate to the wall using the supplied screws.

Diagrams illustrate the mounting plate installation. One shows the two halves of the thermostat being separated. Another shows the mounting plate positioned on the wall, with pencil marks for holes, a bubble level for portrait orientation, and a note about removing the bubble level for landscape orientation. It also shows wires being pulled through the center opening and screws for mounting. A key indicates 'Install Anchors into Drywall' and 'Route wires around this area'.

❗ IMPORTANT! As indicated in the diagram above, route the thermostat wires around the wiring keepout. When the two halves of the thermostat are snapped together the component that rests in that indented area could be damaged.

Making Connections

When making connections, follow the guidelines set below to ensure a safe and secure connection.

1. With a small slotted screwdriver, turn the screws in the connector counterclockwise (CCW) until the silver crimps open enough to slide the wire(s) into the square slots.
2. Strip back insulation on each wire to 1/4 inch and insert the stripped wire into the proper connection.
3. Turn screws clockwise (CW) until the crimps tighten around each wire. Gently tug on each wire to verify they are secure.

Diagram shows a wire with less than 1/8 inch bare wire exposed.

Connect Power - One Transformer used to power the HVAC system

The CLI-W220x does not run on batteries and requires a separate power source to operate. To power the thermostat, voltage must be applied between the RC and 24C terminals. When replacing an existing thermostat, if the power wires removed from the old thermostat were from the R and C terminals, use the diagram below to make the connections.

RC: Connect the wire removed from the R terminal of the old thermostat to the RC terminal. On new installations, connect the wire from the 24V AC HVAC transformer to the RC terminal.

24C: Connect the wire removed from the C (common) terminal of the old thermostat to the 24C terminal. On new installations, connect the common wire from the 24V AC HVAC transformer to the 24C terminal.

Diagram shows a wiring configuration for one transformer, connecting R to RC and C to 24C.

Connect Power - Two Transformers used to power the HVAC system

When an HVAC system uses separate power sources (two transformers) to run the heating and cooling HVAC systems, the HVAC system contains three power wires (R, C, and RC). Adjustments to accommodate the separate power sources are described below.

Diagram shows a wiring configuration for two transformers. It highlights jumper shunt JP1, which connects RH and RC terminals. It advises removing the shunt for separate transformers. It labels RH as supplying power to W1, W2, and O relays, and RC as supplying power to Y1, Y2, and G relays, also powering the thermostat. 24C is labeled as the common terminal required for the thermostat to run. Wires are shown connected to 'Power wire from HVAC heating', 'Power wire from HVAC cooling', and 'Common wire from HVAC'.

• RH: Supplies power to the relays connected to terminals W1, W2, and O.
• RC: Supplies power to the relays connected to terminals Y1, Y2, and G. RC terminal is also used to power the thermostat.
• 24C: Common terminal. The common wire from the HVAC system is required for thermostat to run.

HVAC Wiring

Use the table below when making connections between the thermostat and an HVAC system. The type of HVAC system installed determines which wires are connected and in some installations, the power wires are the only wires required.

HELPFUL!

• Refer to the Making Connections section above to ensure a safe and secure connection is made.

Remote Sensors

GE Wireless Bluetooth Temperature Sensor

Included in the box is an external Bluetooth Low Energy (BLE) temperature flush mount wireless sensor. This sensor is used in place of an internal temperature sensor, allowing for optimal sensor placement to achieve more accurate temperature readings. The sensor must be placed within Bluetooth range of the thermostat, up to 25 feet in open air. Note that signal interference or material obstruction may reduce this effective range.

• See the GE Wireless Bluetooth Temperature Sensor (93129901) QRG (009-2091-xx) for more information on this sensor.
• The GE Wireless Bluetooth Temperature Sensor may be installed with a screw and anchor into a wall, or with the provided adhesive strip. If using the adhesive strip, record the 6-digit pin number on the back. This number will be used during app configuration.
• Up to six (6) GE Wireless Bluetooth Temperatures Sensors can be connected to a CLI-W220 at a time.

Diagrams illustrate the GE Wireless Bluetooth Temperature Sensor, showing its front and back. The back shows a 6-digit pin number.

Optional 10K Type Sensors

The CLI-W220x includes two thermistor ports labeled RS1 and RS2 for 10K type temperature sensors. Like the Bluetooth temperature sensor described above, this sensor can replace the onboard temperature sensor or can be used to calculate an average reading of the temperature in a room or space. The 10K sensors do NOT observe any polarity. Refer to the diagram below when making connections for 10K type sensors or thermistors.

Diagram shows the connection for optional 10K Type Sensors to the thermostat's RS1 and RS2 ports, labeled RX+, RX-, GND.

Example 1:

Example 1 shows eight CLI-REL1AUX1 relay modules. Each module uses the HVAC signaling outputs to control a separate zone.

• Any combination of CLI-REL1AUX1 and CLI-PTAC1K1 modules that equal eight zones is acceptable.
• Any number of sensor type modules can be added once the eight zones are established. Modules such as the CLI-1WIRE2 and CLI-10K4IN do not affect the maximum.

Diagram shows the CLI-W220x connected to eight CLI-REL1AUX1 modules, each controlling a separate zone.

Example 2:

The diagram below shows 3 Aux Relay modules with each relay output controlling a separate damper. Each damper is considered a different zone. Therefore, the maximum number of 8 zones is reached.

• Any combination of CLI-AUX3 and CLI-REL1AUX1 modules that equal 8 dampers/zones is acceptable.
• Once the 8 zones are established, any number of sensor modules (CLI-1WIRE2, CLI-10K4IN) can be added. Those modules do not affect the maximum.
• Use the diagram for reference only. Refer to the QRG's for the CLI-REL1AUX1 or CLI-AUX3 module for information on wiring a vent damper.

Diagram shows the CLI-W220x connected to three CLI-AUX3 modules, with each relay controlling a separate damper, also representing zones.

Frequently Asked Questions:

• Does the CLI-W220x require batteries? No, the CLI-W220x requires 24V AC that is typically available from a transformer or similar in the HVAC system. If the thermostat getting replaced does not include a common (C) wire, a separate wire must be run from the HVAC system to the Savant thermostat.
• How does CLI-W220x get software updates? The thermostat periodically receives Over The Air (OTA) updates automatically from the Savant Cloud. To obtain the update, the CLI-W220x must be connected to a local network that has WAN access, and be configured in a Savant system.
• Will CLI-W220x still work if the Wi-Fi connection is lost? Yes, most thermostat functions still work when not connected to Wi-Fi. However, features such as schedules and OTA updates that require a network connection will not.
• My thermostat was received damaged. What should I do? If the thermostat was purchased through a contractor or retailer, contact the contractor or retailer to return it. If thermostat was purchased from the Savant Store, contact Savant through the Savant Customer Community.
• Are both Fahrenheit and Celsius supported? Yes
• Does the thermostat support humidity? Yes, humidity can be monitored by one of the following: The included GE Bluetooth Temperature Sensor (93129901) or an optional remote 1-wire combination temperature smart sensor is available from the Savant Store (CLI-THFM1).
• Is the thermostat a single or dual setpoint thermostat? Both. The thermostat can function as either a single or dual setpoint thermostat. To do this, select the correct profile from Blueprint and select the right mode (dual or single setpoint) from the thermostat's on-screen menus. For additional information on the Blueprint configuration, see the Multistat Smart Thermostat Deployment Guide available on the Savant Community.
• Does the thermostat support Scheduling? Scheduling is set up only via the Savant Pro App Climate service.
• Can I configure the thermostat to calculate an average humidity reading if I have both the Bluetooth sensor and wired remote smart sensor (CLI-THFM1) connected? Yes, When configured through the web UI, the user decides which sensors to use and whether to take the average.
• What are the maximum number of climate modules that can be connected to a CLI-W220x? There is no fixed maximum number of modules. Instead, the max quantity of modules is determined by the number of zones. Each thermostat supports a maximum of 8 zones. How a user gets to those eight zones can vary. See Example 1 and Example 2 for reference.
