Salus ST100ZB Line Power Fan Coil Thermostat

Introduction

Fan Coil Thermostat System Overview

The SALUS fan coil thermostats provide remote control of fan coil units via the SALUS Smart Home application for smart devices and PCs. Detailed instructions for the SALUS Smart Home application are available in the SG888ZB Pairing Guide.

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, the qualified 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.

Included Parts – ST100ZB Line Power Thermostat

Tools – Required/Optional

Required Tools:

• #1 Phillips or flathead screwdriver

Optional Tools:

• Smartphone or digital camera for wiring reference photos
• Small screwdriver for removing wiring from old thermostat terminals

Before beginning the installation procedure, turn off the power to the fan coil system.

Remove the Existing Wired Thermostat

1. Step 1. If replacing an existing wired thermostat, review and record the wiring configuration of the existing thermostat:
   • Remove the existing thermostat from the wall to expose the wiring terminals
   • Take a photograph or note the wire colors and connections (see wiring reference table below)
   • Attach wire labels to each of the wires

2. Step 2. Label each wire when disconnecting them from the thermostat terminals and remove the thermostat mounting plate (if necessary).
   Paint the mounting surface, if desired, before mounting the thermostat back plate to ensure complete wall coverage.

A split junction box may be required in some jurisdictions to separate line voltage supply wires from low-voltage sensor leads.

ST100ZB Fan Coil Thermostat Installation

1. Step 1. Install the Wiring Mount in the desired location using the junction box screws provided, making sure the wires go through the center opening. An optional wall plate (sold separately) is available for mounting to other junction box configurations (see below).
2. Step 2. Connect wiring to the ST100ZB Back Plate – Use the following chart to identify the desired configuration.

5. Step 5.
   When the battery tab is removed, the red LED will begin to flash.
6. Step 6.
   Open the SALUS Smart Home application, select the drop-down menu from the upper right of the screen and choose: All Devices Add New Device Scan DevicesThe sensor will automatically initiate an operation to associate it with the Fan Coil Thermostat that is in Identify Mode.
7. Step 11.
   If the Fan Coil Thermostat is set to EXT, Parameter P12 is set to 1 (Zigbee remote sensor) and the temperature display shows “- -“ instead of a temperature value, do the following to be sure the SS909ZB
   Temperature Sensor is paired with the Fan Coil Thermostat.

Configuration

Settings Button Operation

Pressing the SETTINGS button will allow adjustment of user-selectable settings.

Special Function Codes

To access special functions, press and hold the keys simultaneously. Use the and keys to scroll through the available codes.

Operation

Operating Modes

The Fan Coil Thermostat can be operated in Standalone Mode, Local Mode or Simple Mode depending on the network and internet connection. The chart below shows how these modes affect the display and operation of the device.
Table 7.1: Operating Modes

Operation	Standalone Mode	Local Mode	Simple Mode
Network State	Thermostat is not part of a network	Thermostat is part of a network, dis- connected from SG888ZB gateway	Thermostat is connected to a SG888ZB Gateway

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 6: Configuration.

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.

1. Temporary HoldTo temporarily override the schedule, simply use the ^ or v 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 off, indicating that the thermostat is following the schedule.
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 off. 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 throughdepending on Parameter P02 (Appendix A) settings. When in mode, the Fan Coil Thermostat will maintain a temperature between the heating and cooling setpoints.

Fan Modes

When in constant fan output, the fan coil will automatically switch to On Call Fan 2 or 4 hours after the
initial call for heat or cool is satisfied (P35).

Accessory Function

Terminals Ac1 and Ac2 on the Fan Coil Thermostat provide output to an accessory such as a Humidifier, Dehumidifier, Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV). The built-in humidity monitor continually samples humidity at the thermostat and will operate a humidifier or dehumidifier to maintain the specified 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.

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 configured by P16 as a Normally Open or Normally Closed contact, or as an input to be ignored.

P16	Ts/Tc Status	P21
		0 (Setback Mode)	1(Off Mode)
0 (Disabled)	Ignored	Inactive	Inactive
1 (Normally Closed)	Open	Setback	Off
	Close	Inactive	Inactive
2 (Normally Open)	Open	Inactive	Inactive
	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 effect   (indicated by “leaf” icon), overriding any schedules.

Troubleshooting

The following error messages are displayed to identify issues when certain conditions occur.
Table 8.1: Error Messages

For Errors 01-04 the display will alternate between the message above and the Home Screen. The total number of errors (shown 01 above) will be the first two digits displayed. If more than 1 error exists, press the and keys to review each error.
