The second stage will turn on at 2x the swing setting. The second stage will turn off when 1x the
swing is reached. For example, if the swing setting is .8 degrees for heating and the thermostat is
set at 70ºF, the first stage will turn on at approximately 69.2ºF. The second stage will turn on at
68.4ºF. The second stage will turn off at 69.2ºF and the first will turn off at 70.8ºF. If third stage is
used, it will turn on at 3x the swing and turn off at approximately 2x the swing.

When turned on the
thermostat will
operate a heat pump.
1.
EM.Heat will show
as an option in the
system switch.
2.
Y will be first stage
of heat & cool, W/E
will be emergency heat
relay & W2 will be
auxiliary heat relay.

Heat - Off - Cool
You can configure the
system switch for the
particular application:
Heat - Off - Cool,
Heat - Off,
Cool - Off,

You can configure the
thermostat to operate
a 3 stage heat pump
system.
2H = 2 heat, 2 cool
3H = 3 heat, 2 cool
The cooling fan delay
setting will delay the
fan from coming on in
cool mode and keep
running after the
compressor shuts off for
a short time to save
energy in some systems.
You can select the
Cooling Fan Delay from
"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.
Use the or
key to change between
2 heat and 3 heat.
2 heat will use Y1 as
first stage and W2 as
auxiliary.
3 heat will use Y1 as
first stage, Y2 as
second stage and W2
as auxiliary.
This option will turn
the heat pump off 45
seconds after the
auxiliary heat relay
turns on.
For 2 heat applications,
the first stage will turn
off 45 seconds after the
auxiliary stage turns
on.
For 3 heat applications,
the first and second
stage will turn off 45
seconds after the
auxiliary stage turns
on.
For heat pump systems
that are “dual fuel”
(use a gas furnace for
auxiliary stage heat)
you can turn this
feature on to turn off
the heat pump when
the auxiliary stage of
heating has been
called for.
