SC102ZB Fan Coil Controller Installation
If replacing an existing wired thermostat, review and record the wiring conguration 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

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 insucient 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.

SC102ZB/ST103ZB Installation and Operation Manual
Operation
Programmable Thermostat (Standalone or Local Mode Only)
When in Standalone or Local mode, the default operation of the Fan Coil Thermostat is as a Non-
Programmable Thermostat with no scheduling capability. Changing the value of Parameter P00 (See
Appendix A) to 1, changes the device to Programmable, allowing users to program a wide variety of
schedule options. Instructions for setting up a schedule are covered in Section 8: Conguration.
• Temporary Hold
To temporarily override the schedule, simply use the or keys to
change the setpoint. When in Temporary Hold, the LCD display on
the Fan Coil Thermostat will show in addition to the icon. The
schedule will resume when the next scheduled time interval begins.
Change the temperature to the scheduled temperature and the icon
will turn o, indicating that the thermostat is following the schedule.
• Permanent Hold
Once in Temporary Hold, press SELECT to toggle between temporary
and permanent override. When in permanent override, the LCD display
on the Fan Coil Thermostat the icon will turn o. The schedule will
be suspended until the user returns it to the schedule changing the
temperature to the scheduled temperature and pressing SELECT.
Heating/Cooling Modes
Heating/Cooling mode selection works the same for both programmable and non-programmable Fan
Coil Thermostats. Parameter P02 (see appendix) determines which heating and/or cooling modes are
available. Pressing the MODE key, will cycle through
depending on Parameter P02
(Appendix A) settings. When in
mode, the Fan Coil Thermostat will maintain a temperature between
the heating and cooling setpoints.
Set Point Override
While following a temperature schedule in any mode, the Fan Coil Thermostat will display the icon.
The schedule may be overridden temporarily until the next programmed time period, or permanently
until the user returns the device to the programmed schedule.

P22 - Accessory Function
Terminals Ac1 and Ac2 on the Fan Coil Thermostat provide output to an accessory such as a Humidier,
Dehumidier, Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV).The built-in humidity
monitor continually samples humidity at the thermostat and will operate a humidier or dehumidier to
maintain the specied value. The Table 9.3 shows the function of the accessory output depending on which
accessory is selected under parameter 22 (See Appendix A).
Table 9.3: Parameter 22 - Accessory Function
Parameter P22 Setting Operation of Ac1/Ac2 dry contacts
0 (No Function) Open
1 (Humidifier)
Closed when humidity is at
or below the set point
Open when the humidity
exceeds the set point
2 (Dehumidifier)
Closed when humidity is at
or above the set point
Open when the humidity is
less than the set point
3 (ERV/HRV) Closed when fan relay is on Open when fan relay is off
The icon is displayed when the Ac1/Ac2 dry contacts are closed.

P16 - AWAY Mode
Fan Coil Thermostat terminals Ts and Tc are used to initiate or terminate an Away state in the device. The
Ts/Tc contact closure is congured by P16 as a Normally Open or Normally Closed contact, or as an input
to be ignored.

2 (Normally Open)

Close Setback Off
A contact state change detected between the two terminals will initiate the Away timers (P19 or P20)
and once the timers expire, the device will enter or exit AWAY mode (indicated by the “person in doorway”
icon). The timers are canceled if the contact input changes while the timers are active.
If Setback is selected when in AWAY mode (P21), the Setback set points (P17 and P18) will be in eect
(indicated by “leaf” icon), overriding any schedules.

Error Message Description Corrective Action
Error 01: Pipe supply sensor circuit is
open, or pipe supply sensor is not
connected. The pipe supply sensor must
be used if Parameter P02 = 3 or 4 (See
Parameters Appendix A).
• Check connection of pipe supply sensor
to terminals
• Replace sensor
Error 02: Pipe supply sensor circuit is
shorted, or pipe supply sensor damaged.
The pipe supply sensor must be used if
Parameter P02 = 3 or 4 (See Parameters
Appendix A).
• Check connection of pipe supply sensor
to terminals
• Check for shorts in pipe supply sensor leads
• Replace sensor
Error 03: Room temperature sensor
circuit is shorted, or room temperature
sensor damaged.
• If sensor is set to External (Settings), and
Parameter 12 (Appendix A) is set to external
sensor, check for short circuit
• If sensor is set to Internal (default), replace
thermostat or use external sensor
Error 04: Room temperature sensor
circuit is open.
• If sensor is set to Internal (Default), replace
thermostat or use external sensor
• If sensor is set to External (Settings), and
Parameter 12 (Appendix A) is set to external
sensor, check wiring or assure sensor is
connected.
• If sensor is set to External and Parameter 12
is set to Zigbee remote, go through the
“Find & Bind” sequence defined in the IOM.
Error 05: Filter is clogged • Change filter
