Existing Wired Thermostat Removal
Use the following procedure to review and record the wiring conguration
before disconnecting an existing wired thermostat.
Before beginning the installation procedure, turn
o power to the fan coil system.
Section 3 SC102ZB/ST103ZB Installation and Operation Manual
SC102ZB Fan Coil Controller Installation
If replacing an existing wired thermostat, review and record the wiring conguration of the existing
thermostat:
• Remove existing thermostat from the wall to expose the wiring terminals
• Take a photograph or note the wire colors and connections (see Table 3.1 below)
• Attach wire labels to each of the wires

Attach controller to the wiring mount by aligning the
connector pins.
Make sure the connector pins are not bent and that
the controller is fully seated on the wiring mount.
If an external antenna (sold separately) is required
due to insucient radio coverage, attach the
antenna, as follows, before attaching the controller
to the wiring mount
Optional External Antenna (Sold Separately)
Use the ANT10RF External Antenna if there is insufficient radio signal at the ST103ZB Wireless
Remote or SS909ZB Remote Temperature Sensor.
Remove the antenna connector cover located on the bottom
of the SC102ZB Fan Coil Controller.
Avoid locations that place large metal enclosures,
piping or dense electrical wires between the
SC102ZB Fan Coil Controller and the ST103ZB
Wireless Fan Coil Remote.
Attach the external antenna to the connector, making sure
the nut is nger tight. DO NOT OVERTIGHTEN the nut.

SS909ZB Remote Temperature Sensor Installation
The SS909ZB Remote Temperature Sensor is OPTIONAL and not required for
all installations.
The SS909ZB Remote Temperature Sensor provides additional temperature input for your Wireless Fan
Coil System. Multiple SS909ZB Sensors can be connected to allow temperature averaging throughout
the conditioned space. Remote Temperature Sensors can be permanently mounted on a wall mounted
or mounted on a stand for desk or cabinet top operation. The Remote Temperature Sensor can be
paired prior to mounting (see Section 7, Device Joining & Pairing for details). For desk top operation,
the SS909ZB Sensors can be moved to dierent locations at any time.
