SST-W100 Wi-Fi Thermostat

Quick Reference Guide

The Savant Wireless Thermostat (SST-W100) is a Wi-Fi® enabled digital thermostat designed to control a Heating, Ventilation and Air

Conditioning (HVAC) system. Use this document as a reference when opening, installing, powering, and connecting to a local wireless network. Once connected, the SST-W100 can join the Savant Control system. For more information on configuring the thermostat, refer to the SST-W100 Deployment Guide (009-0802-xx) and SST-W100

** Note: When connecting power to the thermostat, if there are separate transformers for cooling and heating, the transformer from the cooling system is wired to the 24RC terminal and the transformer from the heating system is wired to the 24RH terminal. In this scenario, jumper JP1 located on the

PCB circuit board must be cut to separate the 24RH and 24RC terminals. Failure to cut this jumper could result is damage to the circuit board when powering the system.

Install Thermostat

The SST-W100 can be mounted to an existing wall. Position the thermostat on an interior wall that is away from direct sunlight or any heating ducts or radiators. If replacing an existing thermostat, prior to removing the old thermostat, switch off power to the heating and/or cooling system. During the removal process, it is good practice to label each wire removed with the reference designator marked on the old thermostat being removed. Follow the instructions below to install the SST-W100 thermostat.

1.

Separate the thermostat from its rear mounting plate by grasping the top and bottom of the rear mounting plate in one hand and top and bottom of the thermostat in the other hand. Pull halves apart by rocking the top and bottom of each half until they separate.

2.

Position the rear mounting plate onto the wall where the thermostat will be located. Verify that writing next to each 8-position terminal block can be read. If not, the rear panel is upside down.

3.

With a pencil, mark the two slots in the rear mounting plate onto the wall.

4.

Drill a ¼ inch hole on each mark.

5.

Insert the wall anchor into the holes drilled and using a #2 screwdriver rotate the anchor into the wall using a gentle forward pressure until the anchor is flush with wall.

6.

Place the thermostat base onto the wall. Pull the wires out through the center cutout located between the two terminal blocks. Screw the rear mounting plate to the wall using the #6 x ¾ in self tapping screws supplied.

Remote Sensors

The SST-W100 supports connecting up to two remote temperature sensors (SST-TEMP1 and/or SST-OTEMP1). These sensors are wired to the SST-W100 using #24 AWG cable. The table below displays the configurations supported through software. Refer to the SST-W100 Wireless Thermostat

Deployment Guide (009-0802-xx) when connecting each of the sensors.

Sensor Descriptions

Internal Sensor - The thermostat has an internal temperature sensor mounted on the PCB circuit board.

RS1 (Remote Sensor 1) - RS1 is hardwired to the terminal block on back panel and is typically mounted in a location away from the thermostat. The

RS1 connection is for internal/indoor (SST-TEMP1) use only and when attached, this disables the internal sensor. RS1 cannot be configured for outdoor use.

RS2 (Remote Sensor 2) - This sensor is hardwired to the terminal block on back panel of the SST-W100 and can be used as either an internal/indoor

(SST-TEMP1) or external/outdoor (SST-OTEMP1) sensor.

Connect to a Local Wireless Network

The SST-W100 integrates into the Savant Control system through the local wireless network. The SST-W100 can connect to a wireless network using a few different methods. The information below describes how to join a wireless network using the SSID of the network. The remaining methods are described in the SST-W100 Wireless Thermostat Deployment Guide (009-0802-xx).
