IS-ZW-TSTAT-100 Basic Thermostat Operation Guide

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 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.

Heating

To set the thermostat to control your heating system, press the Heat/Cool Mode button so the word “Heat” displays. Press again to turn off. The word “Heat” will flash when the thermostat is calling for heat.
2. Press the Temp Up (+) or Temp Down (-) buttons to set the Save Energy temperature for heating (default temperature is 70°F).
After 5 seconds, the display shows the room temperature and the words “Save Heat”.

Cooling

To set the thermostat to control your cooling system, press the Heat/Cool Mode button so the word “Cool” displays. Press again to turn off. The word “Cool” will flash when the thermostat is calling for cooling.

Configuration switch

The Gas/Elec configuration switch for heat control is located under the top cover.
Fan
Press the Fan button to Auto to automatically run the system’s fan during heating and cooling. Press the Fan button to On to run the fan continuously, even without heating and cooling.
The Fan icon comes on when the manual button turns the fan on in Auto (there is no Fan icon with the mode in Off).
If the Gas/Elec configuration switch is set to Elec, the thermostat controls the fan with heat. The Fan icon comes on when the thermostat turns on the fan in heat.
If the Gas/Elec configuration switch is set to Gas, the thermostat does not control the fan in heat. The Fan icon does not come on because the HVAC is controlling the fan.
The thermostat always controls the fan with cool. The Fan icon comes on when the thermostat turns on the fan in cool.
When the thermostat is controlling the fan, it runs 1 minute after shutting off the heat or cool (purging).

Displaying Fahrenheit or Celsius

To set the temperature display to Fahrenheit or Celsius, use the F/C switch located under the top cover. Set the switch to F for Fahrenheit or C for Celsius.

Reset

The Reset button (located under the top cover) defaults all programming to target temperatures (heat 70°F, cool 75°F)

Using the Save Energy button

The Normal and Save Energy buttons allow you to quickly switch from the normal programmed target temperature to a predetermined setback temperature, called the Save Energy temperature.
In cool mode:
1. Press the Save Energy button.
The words “Save” and “Target” appear.
2. Press the Temp Up (+) or Temp Down (-) buttons to set the Save Energy temperature for cooling (default temperature is 75°F).
After 5 seconds, the display shows the room temperature and the words “Save Cool”.
To return to the programmed target heat or cool temperature (depending on which mode you are in), press the Temp Up (+) or Temp Down (-) buttons to change the target temperature. After 5 seconds, the display shows the room temperature. Alternatively, to cancel save energy mode, press the Save Energy button to go back to your previous non-setback temperature.
The Save Energy button sets back the temperature up to 4 degrees.

Joining a Z-Wave network

To join a Z-Wave network, remove the top cover and press and release the Mate button. You will also use the Mate button when excluding the thermostat from a Z-Wave network.

Battery operation

The thermostat batteries are not for operation, but provide battery backup for your settings. The thermostat requires 24 VAC for operation, and the HVAC system will stop functioning if the thermostat loses power. Replace the batteries once per year.
To replace the batteries:
1. Change the Heat/Cool Mode button to Off and change the Fan button to Auto.
2. Remove the bottom cover section to access the battery compartment.
3. Remove the old batteries and insert three new AA Alkaline batteries according to the polarity noted in the battery compartment. (Do not use rechargeable batteries).
4. Replace the bottom cover section.
In heat mode:
1. Press the Save Energy button.
The words “Save” and “Target” appear.
