Thermostat Installation Sheet 

Description 

The IS-ZW-TSTAT-100 is a digital thermostat that you can control 
wirelessly. The IS-ZW-TSTAT-100 operates as a simple thermostat 
with buttons to set target temperatures for heat and cool modes.  

The thermostat is compatible with standard 24 VAC heating and 
cooling systems, up to single-stage heat, one-stage cool. The 
thermostat is designed for indoor use only.

The thermostat CANNOT be used with a line-voltage system. Line 
voltage or high voltage thermostat systems run off your home’s 
120 V or 240 VAC power and are not particularly common as they 
are used primarily for electric resistance heating systems. The 
wires on a line-voltage system will be thicker electrical wires like 
those used for a light switch or outlet. Low voltage wiring looks like 
telephone or speaker wire. If you are not certain of the type of 
system, call an electrician or HVAC service. 

The thermostat features include: 

• 

Two-way communication as part of a Z-wave network can be 
controlled both locally and remotely. 

• 

A Save Energy button adds two more modes for target 
temperatures to provide a single button setback mode for 
easy operation. 

• 

The digital thermostat allows you to easily set your desired 
heat or cool temperatures on the large screen with the Temp 
Up (+) and Temp Down (-) buttons.

Installation 

Caution: 

To avoid electrical shock and to prevent damage to the 

furnace, air conditioner, and thermostat, disconnect the power 
supply before beginning work. You can do this at the circuit 
breaker, or at the HVAC system. 

Note: 

Verify the current system is operating properly before tuning 

off the power. 

• 

Do not turn electricity back on until work is completed. 

• 

Do not short (jumper) across electric terminals at the control 
on the furnace or air conditioner to test the system. This may 
damage the thermostat. 

• 

All wiring must conform to local codes and ordinances. 

• 

The thermostat relay load should be limited to 1.0 amp; 
higher amperage may cause damage to the thermostat. 

Tools 

You will need a small Phillips screwdriver. 

New construction installations 

For new installations (new construction), contact your local HVAC 
or electrician to wire and mount the thermostat. 

For new installations and for relocating an existing thermostat, 
follow these guidelines: 

• 

Determine what type of HVAC system you have. 

• 

Locate the thermostat on an inside wall, about 5 ft. (1.5 m) 
above the floor. 

• 

Do not locate the thermostat in unusual heating conditions.  

• 

Do not locate in unusual cooling conditions. 

• 

Do not locate the thermostat in a damp area. This can lead to 
corrosion that will shorten the thermostat life. 

• 

Do not locate the thermostat where air circulation is poor.  

• 

Do not install the thermostat until all construction and 
painting is completed. 

The thermostat does not require leveling.
