WIRELESS TYPE SELECTION
This Wireless Zoning System contains selectable wireless communication. Each component has a jumper switch
labeled FSK and ASK. Default setting: FSK
• All components must be set to the same position for wireless communication.
• Both modes utilize a 916 MHz frequency.
• FSK: frequency-shift keying, this mode improves the signal transmission through dense materials.
• ASK: amplitude-shift keying, set all components to this mode in applications requiring use of the
W150W Wireless Repeater. All components are compatible with the Wireless Repeater in this mode.
(*The Wireless Repeater is an optional accessory to achieve exceptionally long wireless range. Most
installations will not require the Wireless Repeater.)

Step 1.
Step 2.
Press and hold the Base Module button for 3
seconds. The Blue LED will ash when ready to
recieve initial signal from the Master Thermostat.
(Base Module must be powered by 24V. Blue LED
will be continuously on when 24V power is present.
Hold the Light key (shown here) of the Master
Thermostat for 10 seconds, the Blue LED on the
base module will stop ashing after communication
has been established between base module and
the Master Thermostat.
The Blue LED on the base module will be on
when power is present. The Blue LED will
ash 3 times every time it recieves a signal
from Master Thermostat. When a relay is on the
corresponding LED relay indicator will be on.
If the base module does not recieve a signal
from the Master Thermostat for 15 minutes it
will turn o all relays until communication is
reestablished. The Blue LED on the base module
will also turn o to show communication has
been lost.
If communication has been lost for 1 hour and
if freeze protection is enabled, heat and
emergency heat relays will be turned on. The
heat and emergency heat relays will turn on for
10 minutes every hour if there has been a call for
heat in the last 24 hours.
DO NOT hold the light button
on the Master Thermostat for
more than10 seconds after Step
2 above has been completed.
Holding the light button down
will break the communication
link and the base module button
will need to be pressed again to
reestablish communication.

compressor to run for
at least 4 minutes
every time the
compressor turns on,
regardless of the room
temperature.
The heating swing
setting is adjustable
from ±0.2°F to
±2°F. For Example:
A swing setting of
0.5°F will turn the
heating on at
approximately 0.5°F
below the setpoint
and turn the heating
off at approximately
0.5°F above the
setpoint.
Pick PA or FU
PA = partial keypad
lockout, which locks
all the keys except the
or keys.
FU = Full keypad
lockout, which locks
out all the keys.
Note: Keypad lockout
instructions are below.
The cooling swing
setting is adjustable
from ±0.2°F to
±2°F. For Example:
A swing setting of
0.5°F will turn the
cooling on at
approximately 0.5°F
above the setpoint
and turn the cooling
off at approximately
0.5°F below the
setpoint.

All programmable thermostats are shipped with an energy saving pre-program. You can customize
this default program by following the Set Program Schedule.
Your thermostat can be programmed to have each day of the week programmed uniquely (7days), all the
weekdays the same with a separate program for Saturday and a separate program for Sunday (5+1+1),
or nonprogrammable. There are four time periods for each day ( WAKE, LEAVE, RETURN , SLEEP ).
This thermostat has a programmable fan feature, which allows you to run the fan continuously during any
time period. Programmable fan is available for Local Zone 1.

Note: The scheduled programming for ALL zones is done by and kept in the memory of the
Z955W Mater Thermostat. Although CONTROL of an independent zone can be given to that
zone’s thermostat, its programming is done by the Master Thermostat.
