The IS-ZW-TSTAT-300 programmable communicating thermostat operates via a high-quality, easy-to-use touch screen. To program or adjust your thermostat, simply touch your finger firmly to the screen. The screen will automatically light up and you will hear a “beep”. The screen will respond differently to different types of touches, so you may want to experiment by touching it in different ways, finger, fingernail, etc. Do not use a sharp or metallic device; it will scratch the screen.


Control screens

Before you operate the thermostat, you should get familiar with these basic control screens. All the thermostat functions are accessed through these screens: Home, Menu, Program, and Manual. The touch screen technology allows you to select (by touching) an item and change it using the +/- arrows or the time arrows.

Home screen

The Home screen is displayed when the unit is operating. This screen shows you the current settings and conditions.


To set a mode, press the MODE button on the side of the thermostat. The thermostat will step through the HEAT, OFF, and COOL modes in order. The LCD display indicates the mode you are in.

Menu screen

To display the Menu screen, press the Menu button.


Use the Menu screen to access the following thermostat functions and settings:

Time of day Touch the left (down) or right (up) arrows next to the time display to set the current time (1 minute per touch). Touch and hold the arrow for a fast time set (15-minute jumps).
Day of week Touch the Day area to select the present day.
FILTER The thermostat can be programmed to remind you when the HVAC system’s air filter needs changing.

Touch FILTER. The display will show the usage to date.

Touch FILTER for over 3 seconds and the display will change to LIMIT. Touch arrows to set the desired usage limit before the filter alert comes on the Home screen. When this limit is reached, FILTER will display on the Home screen.

You can set the limit from 0 to 999 days (the default is 90 days). To reset the usage back to 0, touch the usage number; touching it again restores the displayed usage.

SWING This feature allows you to set the desired variance in temperature between the thermostat setting and the room temperature required before the heating or cooling system will turn on – from 0.5 to 2.0°F (0.25 to 1°C). For example, if SWING is set to 2.0°F and the thermostat is set to 70°F target temperature, the heat cycle will start when room temperature drops to 68°F. Similarly, the cooling system will start when the room temperature increases to 72°F. The HVAC then runs and will shut off at the target temperature.

To set the feature, touch SWING. Touch the left/right arrows to set the SWING from 0.5 to 2.0°F. The HVAC will run more frequently at 0.5°F and less at 2.0°F. The default is 1.0°F. Touch the Home icon to return to the MENU screen.

DIFF (differential) (This feature is used for two-stage normal or heat pump with aux only, the feature is not on screen for single stage.)

The differential is the number of degrees between the room temperature and the target temperature at which the second stage will be used. The default is 2°F.

Touch DIFF. Use the arrows to set the differential. We recommend 2°F for very cold climates and 4°F for warm climates.

CALIBRATE Your thermostat was accurately calibrated at the factory to ± 1°F of actual ambient temperature. You do have the option, however, to change the display temperature to match that of a previous thermostat, or to match another thermostat already in your home. The rage of change is from -6F to

+ 6°F or -3 C to +3°C.

To change your thermostat calibration, touch CALIBRATE. Use the +/- to adjust the displayed temperature up or down as desired. The Delta Factor that appears on the screen will also automatically increase or decrease for each 0.5°(F or C) adjustment so you can see your change. The large display will show the modified temperature reading that will be displayed on the Home screen and used as the new room temperature.

HVAC setup Touch to configure the unit to work with your HVAC system.
Chirp icon Touch to turn the audible chirp sound on or off.
°F/°C Touch to toggle the temperature display scale between °F and °C.
Unlock/Lock icon The thermostat has two lock modes. Touch the Unlock icon for 3 seconds; the unit will go into the Partial Lock mode (Lock icon with one bar). You can temporarily override the thermostat target temperature with the +/- buttons.
For full lock, touch the Lock icon again for 5 seconds to go to Full Lock mode (Lock icon with two bars). No changes can be made. Once locked, the thermostat will respond just to the mode and menu. To unlock, press the Menu button. Touch and hold the Lock icon for 5 seconds for two bars (if not there already). Then touch and hold the Lock icon for another 5 seconds. Each 5-second touch and hold must be separate.
Home icon Return to the Home screen.

Program screen

Press the Prog button to display the Program screen. Use the Program screen to program thermostat control for your home HVAC system.Interlogix-IS-ZW-TSTAT-300-Wireless-Thermostat-FIG.4

Day Touch to set the day of the week for which you want to program target temperatures.
Time slot Touch to set the time slot (MORN, DAY, EVEN, or NITE) you want to program.
Program time Touch to set the time of day you want the time period to start. The left arrow goes back, and the right arrow goes forward (touch and hold for the fast set).
Temperature up/down arrows Touch these to raise or lower the target temperature for the time slot (touch and hold for the fast set).
COPY DAY Touch to copy the current day’s program to the next day.
Home icon When programming is complete, touch the Home icon to run your program and return to the Home screen.

Manual screen

Touch the large current temperature display in the middle of the Home screen to access the Manual screen.
You can use the Manual screen to make temporary changes to your thermostat’s operation.
Note: The mode must be HEAT or COOL to access the Manual screen.Interlogix-IS-ZW-TSTAT-300-Wireless-Thermostat-FIG.5

Temperature up/down arrows Touch to raise and lower the manual override target temperature.
Manual override indicator Touch the +/- arrows to select your desired temporary target temperature. Touch the Home icon to return to operation. The TEMPORY icon will display indicating you have modified the target temperature for the current time slot only. It goes back to the program target in the next period. Also, when in TEMPORARY, if the target is set the same as the programmed target for that period, the word TEMPORARY will not display.
HOLD Touch to operate the thermostat as a manual thermostat. This will hold the target temperature you set indefinitely until you turn to HOLD off. Use care when using the HOLD function as the program is now bypassed. To set a hold target temperature, touch HOLD and use the +/- icons to select your hold temperature. The HOLD icon will display on the Home screen indicating you have changed the target temperature. The system will hold this temperature until you return to the Manual screen and deselect HOLD by touching it. HOLD is also canceled when you set the mode to OFF
HOLIDAY Touch to invoke a single program that repeats day after day until you turn it off. It supersedes the weekly program. To use it, touch HOLIDAY. The default holiday program is shown (HEAT 70°F all day and 62°F at night; COOL 78°F all day and 82°F at night). To modify this program, touch the PROG button and then touch the Day area until HOLIDAY appears (after SAT).

(heat pump only)

If you set your thermostat for HEAT PUMP with auxiliary heat, the EMER function is available on the Manual screen. If you touch EMER, it displays EMER|ON. You heat pump is disabled and auxiliary heat is your sole source of heat. This manual override stays active until you toggle EMER off.

Auxiliary heat is more expensive than the heat pump, so use EMER only if the heat pump cannot keep up or is defective.

Hold down the Prog button for 10 seconds to access the limited display screen. Hold down the Prog button for 10 seconds to leave the limited display screen.
  • Compressor protection
    The thermostat has a minimum cycle time of 4 minutes to protect your compressor in cool and in heat pump (if you have one). The Home screen will show a small clock and A/C during this time and the compressor will not come on until the 4-minute delay is over.

Communicating thermostat

The thermostat has two RTM-1 radio ports. These allow your thermostat to communicate with other systems. Depending on your area power company, programs may be available to connect your thermostat to power grid status information. This can make it easy for you to moderate your energy use at peak hours and use power when it is less expensive.Interlogix-IS-ZW-TSTAT-300-Wireless-Thermostat-FIG.6

The USNAP ports allow you to connect your Thermostat to your home Z-Wave network. This can give you access to your home’s HVAC system even when you are away (with additional web service). It can also give you access to web-based efficient energy management sites that can help you save money and protect the environment. You can connect your thermostat to an AMI network for an in-home display of electric grid status or connect to a home automation network for HA functionality with remote access to your HVAC system and home conditions.
To insert a USNAP radio module, power off the thermostat, insert the radio module in either slot on the back of the thermostat, and then power up the thermostat.
To connect to a network, follow the instructions that come with the USNAP module.
Caution: Do not insert or remove USNAP radio modules if power is on. This can damage the thermostat or radio modules.
