Description

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 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.

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

P/N 1069511 • REV B • ISS 12FEB13 3

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 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 (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.
