Test and Balance Switch (S1)
NORM: Sensor operates normally
LOW: Sets the sensor value low
HIGH: Sets the sensor value high
On the Test and Balance Switch, the NORM position allows the real sensor to be monitored. The HIGH position forces the
output to a very hot reading and the LOW position forces a very cold reading (see Table below).

The unit is available with
optional Fan Speed and
System Mode Control.
The resistive outputs for
the various options is
shown in the table at right.
The option is selected at
the time of order and the
resistive value is output to
the FAN terminal.
