Introduction
Product Safety Information
Please read these instructions carefully BEFORE INSTALLING AND USING the Fan Coil
Thermostat. DO NOT supply line voltage (120 or 240 VAC) to a ST101ZB Low Voltage Fan Coil
Thermostat.
• DO NOT cover any of the vents on the thermostat
• DO NOT place the unit in a bathroom or area of excessive moisture
• DO NOT allow the unit to get wet. This device serves as a temperature control system only in
dry, closed living and office spaces.
• DO NOT use solvents or aggressive cleaning agents. A dry, soft cloth is recommended for
cleaning.
The manufacturer does not accept responsibility for any damage caused by not following these
instructions.
Codes & Regulations: Installation and setup of this product must be performed in strict
compliance with national, state/province, and local codes. Additional code requirements
for line voltage-powered devices may apply to the ST100ZB Line Power Fan Coil
Thermostat. An authorized, qualied installer may be required.
Intended Use: SALUS ST100ZB/ST101ZB Fan Coil Thermostats are intended for interior
room temperature control in conjunction with fan coil heating systems only. Other uses
are not recommended or supported.
Installer or Contractor: Record parameters at startup and any subsequent parameter
changes in the installer notes section of this manual.

will turn o, indicating that the thermostat is following the schedule.
7.3.2 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.
7.4 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.
7.3 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.

Operation
Section 7.0
7.6 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 following table shows the function of the accessory output depending on
which accessory is selected under parameter 22 (See Appendix A).
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.
33
7.7 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.

Operation
Section 7.0
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.

Troubleshooting
Section 8.0
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
The following error messages are displayed to identify issues when certain conditions occur.
