Operation; W8665E Single And Multi-Stage Operation - Honeywell W8665A Manual

SETUP
Setting Up W8665A,E to Receive Signals
from the T8665A Thermostat(s)
The T8665A Thermostat(s) require(s) setup to send
signals to the W8665 Receiver Module to operate:
• The W8665A Receiver is used for single-zone
applications.
• The W8665E RF Zone™ Panel is used for up to three
T8665A Thermostats for multi-zone applications.
IMPORTANT
Be sure the thermostat is at least five feet away
from the W8665 during setup. Maximum dis-
tance is 200 feet.
Single Zone Applications (1 W8665A/1 T8665A)
1. Power up the W8665A and install the batteries in
the T8665A Thermostat.
2. Place the W8665A Zone 1 DIP switch to the On
position.
NOTE: The W8665A Zone 1 LED will flash.
3. Press the thermostat Fan key to On:
a. The receiver accepts the message and stores
the identity.
b. The zone 1 LED stops flashing.
c. The thermostat is now set to send signals to

NOTE: The word, On, and a fan blade
thermostat display to indicate the thermostat is
calling for the fan to turn on.
d. Use Fan key to turn off fan.
4. Set System and Fan keys to the desired locations.
NOTE: At any time, if you want to stop the thermostat
from sending signals to the W8665 Receiver,
turn the DIP switch to Off. Then repeat steps 1-
3 to set up the thermostat to send signals to the
W8665 Receiver.
Multizone Applications (1 W8665E/Up to 3
T8665A)
1. Power up the W8665 and install the batteries in the
T8665 Thermostats.
2. Set the thermostats so no zones are calling for sys-
tem or fan.
3. Set up each zone separately to ensure that a
unique address is used for each zone.
4. Place the zone 1 DIP switch on the W8665E
Receiver to the On position.
NOTE: The W8665E zone 1 LED will flash.
5. Press the thermostat Fan key to On:
a. The receiver accepts the message and stores
the zone identity.
b. The zone 1 LED stops flashing.
c. The thermostat is now set to send signals to
the W8665E Receiver.
NOTE: The word, On, and a fan blade
thermostat display to indicate the thermostat is
calling for the fan to turn on.
NOTE: At any time, if you want to stop the thermostat

8. Attach the zone number sticker, included with the

OPERATION

W8665A Sequence of Operation
appear in the
On a call for heating or cooling, the thermostat sends a
signal to the W8665A to bring on the heating or cooling
until the call is satisfied. The Comm LED flashes when
the W8665A receives a signal from the thermostat to turn
on the system or approximately every ten minutes as a
status update. On a call for heating, cooling or fan, the
zone LED lights red.
W8665E Sequence of Operation
On a call for heating or cooling from any zone, the
thermostat sends a signal to the W8665E to bring on the
heating or cooling in that zone until the call is satisfied.
The Comm LED flashes when the W8665E receives a
signal from the thermostat in any zone to turn on the
system or approximately every ten minutes as a status
update. On a call for heating, cooling or fan, the zone
LED lights red.
W8665E Single and Multi-Stage
Operation
The first stage is energized by the thermostat.
To control multistage conventional and heat pump
systems, the W8665 must be wired to a zone control
panel that is able to control multiple stages of heat and/or
cool (such as the EMM-3U Universal Electronic MiniZone
Control Panel or TZ-4 TotalZone® Zone Control Panel).
The zone panel (not the RF panel) controls these stages
based on the number of zones calling or with a timer. See
the Zone Control Panel Instructions for more details on
how to control up to three stages of heat and two stages
of cool.
