Salus ST101ZB Low Voltage Fan Coil Thermostat Installation Guide

Salus ST101ZB Low Voltage Fan Coil Thermostat

Notices
Please read these instructions carefully before installing and using the Line Power Fan Coil Thermostat.

• Follow all national and local electrical codes, ordinances, and regulations regarding the installation or replacement of a line power thermostat. An authorized, the qualified installer may be required.
• 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.

The manufacturer does not accept responsibility for any damage caused by not following these instructions.

Let’s Get Started

Make sure you have the following items:

Tools

•  Phillips or flathead screwdriver
• Small screwdriver for terminals

Optional Tools

• Smartphone or digital camera to take pictures of wiring for later reference
• Screwdriver to disconnect wires from old thermostat
• Pencil

Turn Off the Power to the Fan Coil System
This is usually accomplished by turning off the circuit breaker in the breaker panel.

Determine Wiring Configuration

• Remove the old thermostat from the wall to expose the wiring terminals.
• Take a picture of the wiring for future reference.
• Note the terminals attached to each wire and attach the matching label to the ends of the wires.

Use the following table as reference: 

Terminal Name	Function
	4 pipe system	2 pipe system
R	24VAC input
C	Common of AC input
WY	Hot water valve output	Pipe valve output
YA	Chilled water valve output	Auxiliary Heat (A)
Gl	Fan coil low speed control
Gm	Fan coil medium speed control
Gh	Fan coil high speed control
Ac	Accessory output (relay contact)
Ac	Accessory output (other side of relay)
Tp	Pipe temperature sensor input
Tx	External temperature sensor input
Ts	Setback contact input
Tc	Tx/Tp/Ts common

Remove Old Thermostat Terminals

After all wires have been labeled, carefully remove the wiring and any mounting or back plate from the old thermostat.
Tip: Wrap the wires around a pencil to prevent them from falling into the wall space
Note: If you intend to paint the mounting surface, now is the best time to do so to insure complete wall coverage behind and around the thermostat without the use of a back plate.

Install Wiring Mount

Remove the wiring mount from the packaging, and use the included wall screws and/or anchors to attach the wiring mount to the wall, making sure the wires run through the center opening. If alternate mounting holes are required, use a wall plate (sold separately).

Attach Wiring

Connect the labeled wires to their matching terminals based on the fan coil configuration as follows:

Note: If using more than one T terminal (Tp,Tx,Ts), it may be necessary to splice for Tc.

Attach Thermostat to Wiring Mount

Attach the thermostat to the wiring mount by aligning the connector pins and the plastic retention posts and pushing the thermostat onto the wiring mount.
Make sure the connector pins are not bent and that the thermostat is fully seated on the wiring mount.

Turn On Power to the Fan Coil System
Turn on the circuit breaker at the breaker panel to power up the fan coil system and thermostat.

Pair Thermostat
After powering up and initializing, the thermostat will display the pairing screen.
Consult the pairing guide for your home automation system to determine how to add the Low Voltage Fan Coil Thermostat to your system.
After pairing, the device will automatically enter Installer Mode to allow configuration of the device.
To skip the pairing process and enter Installer Mode immediately, press SETTINGS ( ).

Configuring the Thermostat

In Installer Mode, the buttons have the following function:

Button	Function
SELECT short press long press (~2s)	Save displayed value for parameter and, go to next parameter (wrap around at end back to 0) go to previous parameter (wrap at 0 to end of parameters)
	Up or down selection of value options for parameter
SETTINGS	Exit Installer Mode and go to Home screen

For the purposes of this Quick Start Guide, only the minimum essential parameters are covered. To view the full list of parameters, please consult the User Manual at www.salusinc.com.

Parameter	Name	Values (default in bold)
P00	Thermostat Type	0 = Non-Programmable (for home automation systems with schedules) 1 = Programmable
P01	Fan Coil Type	0 = 2 Pipe 1 = 4 pipe

Parameter	Name	Values (default in bold)
P02	Heat/Cool Configuration	For 2 Pipe: 0 = Heat Only 1 = Cool Only 2 = Heat or Cool Manual changeover 3 = Heat or Cool Seasonal changeover (Pipe sensor required) 4 = Heat or Cool with Auxiliary Heat (Pipe sensor required)	For 4 Pipe:
			2 = Heat or Cool Manual changeover 3 = Heat, Cool or Auto changeover 4 = Auto changeover only
P03	Pipe Valve Type	0 = Normally closed 1 = Normally open
P12	External Sensor Type	0 = External sensor 1 = Zigbee remote sensor
P13	Pipe Sensor Type	0 = Analog input 1 = Normal open, default mode is Heat 2 = Normal open, default mode is Cool 3 = Normal close, default mode is Heat 4 = Normal close, default mode is Cool

Normal Operation

After exiting Installer Mode, the device will go to the Home Screen with the following button functions.

Button	Function
