BULLDOG SideWinder – Installation, Operation, and Maintenance Manual
e. If during compressor operation the condenser leaving temperature rises above
140
°
F, compressor operation will be disabled. After 10 minutes an auto reset
occurs and the compressor will be enabled as soon as the temperature drops
below 120
°
F. The outgoing system fluid sensor is mounted on the leaving fluid
pipe. Actual compressor restart will be delayed a minimum of 5 minutes by the
anti-recycle timer. A flash code of 3 will be initiated upon a high outgoing system
fluid temperature shutdown.
f. If the discharge air temperature drops below 40
°
F, compressor operation will
be disabled. After 10 minutes an auto reset occurs and the compressor will be
enabled as soon as the temperature rises above 55
°
F. The discharge air
temperature sensor is mounted on the fan housing. Actual compressor restart
will be delayed a minimum of 5 minutes by the anti-recycle timer. A flash code
of 4 will be initiated upon a low discharge air temperature shutdown.
g. The condensate level sensor is a 100 ohm thermistor that is heated for 15
seconds every 4 minutes. Its temperature is measured at the beginning of the
heat cycle, and again at the end of the heating cycle. If the condensate level
rises above the sensor it will not warm up during the warm up cycle, and the
temperature change will be insignificant. It is this lack of temperature change
that the controller sees as an impending condensate overflow. When high
condensate level is detected, compressor operation is immediately terminated,
and at the same time the fan is stopped for 30 seconds, and then restarted. At
this time a flash code of 7 will be initiated. The 4 minute cycle will continue until
the cooling call is no longer in place. If the condensate level drops below the
sensor, compressor operation will be returned to normal. However, if the
condensate level stays above the sensor for more than 15 minutes, the fault
alarm will be triggered. This fault signal will automatically reset once the
condensate level goes below the sensor.
Note: The last flash code will be maintained in memory for 1 week or until the unit controls are
powered down. The flash code will continue until the problem has cleared and the compressor has
been put into operation. If a cooling call is in place, it must be disengaged before the cause of the
last alarm shutdown can be identified.
