7.1 Switch Settings
SWX 1 - Lock
This switch is used to lock the
controller. When it is on, the user may
change settings such as target
temperature and minimum speed/timer
percentages but they can not change the
settings in program mode. If the switch
is set to ON the program settings are
locked.
SWX 2 - Fahrenheit/Celsius
This switch toggles between Fahrenheit
and Celsius operation. If the switch is
set to ON, the controller will read the
sensors as Fahrenheit. (Note: If you
change this switch, you will have to
reset your tunnel on points and off
points and your Target Temperature.)
SWX 3 - 5/10 minute timer
This switch selects between a 5 and 10 minute system timer. If the switch is ON, the timer is
10 minutes.
SWX 4 - Curtains independent
This switch is used to choose whether the curtain machines operate off the same sensor or if
they operate independently. If the switch is ON, the curtains are independent with curtain 1
running on sensor 1, and curtain 2 running on sensor 2.
SWX 5 - Tunnel On/Off
This switch is used to enable or disable the tunnel mode of the controller. When this switch is
in the OFF position, the controller will not go into tunnel for any reason.
SWX 6 - Tunnel On Stage
This switch tells the controller whether it is tunneling off of the lowest programmed tunnel
stage or if it is tunneling off of outside temperature. If this switch is set to the ON position,
the controller will switch to tunnel mode whenever the first programmed tunnel stage comes
on. If this switch is OFF, the controller will use the “Tunnel On Point” setting for entry into
tunnel.
SWX 7 - Power Ventilate
This switch indicates whether this is a power ventilated house or a natural ventilated house.
If it is a power ventilated house the controller will leave the inlet curtain closed until tunnel
mode is entered. This switch must be set to ON if you have a Power Ventilated house.
SWX 8 - Program ‘A’ or ‘B’
This switch is used to toggle between 2 preset programs. This could be used to store separate
summer/winter programs for instance. The ON position is for Program A, and the OFF
position is for Program B.
