7. Rarely Changed Settings
Settings which are rarely or never changed are found on a bank of switches located inside the front
panel of the controller. The upper position is ON, the lower position is OFF. Switches number from
left to right. The functions of the switches are as follows:
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 tunnelling off of the lowest
programmed tunnel stage or if it is tunnelling off of outside temperature. If this
switch is set to the ON position, the controller will switch to tunnel mode whenever
