The cooling fan delay setting will
delay the fan from coming on in
cool mode and keep it running
after the compressor shuts off
for a short time to save energy in
some systems.

You can set the cooling fan
delay to OFF, 15, 30, 60 or 90
seconds. If 15, 30, 60, or 90 is
selected the fan will not turn
on for that many seconds
when there is a call for cool
and will run for that many
seconds after satisfying a call
for cool.

the thermostat is able to
connect to up to four indoor

Use or to select the
zone you wish to connect.
The zone setting on the
master and the indoor

Note:
When the dehumidify terminal is configured as normally-closed,
the base module D terminal LED indicator will be lit when the relay is
closed. When the thermostat calls for dehumidification, the D terminal
LED indicator will turn off.
Note:
Up to four indoor temperature sensors can be connected to one
thermostat. This allows for 5 sensing points (zones). For example: the
local (thermostat) plus four indoor sensors enables 5 sensing points.
To connect an indoor sensor to a thermostat, select 1 on the FINDING
SENSOR technician setup step. Then hold down the light button on the
indoor sensor until it beeps, while in ZONE technician setup step on the
indoor sensor. To connect a second indoor sensor change the
thermostat to read 2 and change the indoor sensor to zone 2. The zone
setting must match between the thermostat and the indoor sensor to
connect. When the connection is established the thermostat will show
FOUND + NAME of the indoor sensor in the system information area of
display.
Balance Point:
The system operates differently when a balance point is used. On a dual
fuel system, the balance point outdoor temperature setting will be the
outdoor temperature at which the thermostat chooses either the heat
pump or gas furnace. For example: A balance point setting of 30°F will
turn on only the heat pump above 30°F and only the gas furnace below
30°F. Y1 will be stage one above 30°F and W2 will be stage one below
30°F. A heat pump with electric auciliary will energize the heat pump
above and below balance point. The electric auxiliary will only energize
below balance point. For Example: A balance point setting of 40°F, will
turn on the heat pump above 40°F and turn on the heat pump and
electric auxiliary below 40°F.
