If
LIGHT
is selected, the next prompt displays a light intensity set point:
LIGHT TRIP: 0.7%
The Light Probe is connected to the Sensor #2 input and is calibrated to produce a reading of 100% in direct
sunlight on a clear summer day at mid latitudes. There is generally sufficient light to wash cars down to about
0.5% of full sunlight intensity. See the application note later in this document for more lighting information.
When light levels fall below the Light Trip value, the Aux #1 Output relay will be energized. About 100%
hysteresis is provided on this Light Trip value to prevent the Aux #1 Output relay from being energized and
de-energized as moving clouds and other factors vary near sunrise and sunset. You can change the temperature
trip set point by using the
+/Yes
and
-/No
keys. The
Next
key will save the new value and advance the menu
to the next item.

If
TIME
is selected, the next two prompts display the time at which Zolar will energize the Aux #1 relay.
ON TIME: '08:00
(note the PM indicator just before the numerical digits)
OFF TIME: 06:00
Times can span midnight. For example, if you wish to have lights come on at 8:00 PM and go off at 6:00 AM,
set On Time and Off Times as shown in the example above. The
+/Yes
and
-/No
keys will modify this time
set point if desired and the
Next
key will save the values and advance to the menu to the next parameter.
After the Weep and Aux outputs are configured, Zolar presents information for the Foam Blower output set point.
FOAM BLOWER TEMP: °F 34
The Foam Blower output is controlled by the lower of temperature sensor #1 or temperature sensor #3 (if installed). At
temperatures above the set point, the Foam Blower output will be active low. At temperatures below the set point, the
Foam Blower output will be inactive. Once the Foam Blower becomes active, the temperature must rise 2°F above the
set point before the output will switch to inactive (2° hysteresis). The
+/Yes
and
-/No
keys will modify the set point
and the
Next
key will save the values and advance to the menu to the alarm parameters.
TEMP #1 ALARM LOW: °F 55
The last set of parameters presented in the Configuration Menu is for Zolar’s Auto Dialer Alarm capability, which may
be triggered by either a temperature extreme or a power outage. If the power fails for any reason, the Auto Dialer will
be triggered as soon as power is restored. Zolar will only prompt you for Alarm set points for those Sensor Inputs
having attached Temperature Probes. Since Sensors #1 and #3 are each associated with a Weep Output they will trigger
an Alarm for a low temperature only. Since Sensors #2 and #4 can be used to sense temperatures that are too low, or too
high, they can trigger an Alarm Output if the temperature gets either too cold or too hot. This output is designed to be
used with an Auto Dialer to provide a phone call to an off-site location but could also provide some local alarm
annunciation if desired. Each temperature set point can be individually adjusted using the
+/Yes
and
-/No
keys.
To avoid repeated “nuisance” calls for the same problem, once triggered, the alarm output will not re-trigger until all
trigger sources have maintained a clear state for at least one continuous hour. As there are no more parameters to
configure, the
Next
key will now return to the Status display.
LOWEST TEMPERATURE: F 12.5 RESET? Y/N
Zolar will keep track of the lowest temperature recorded since last time the value was reset. A Yes response to the
prompt above would reset the lowest temperature to the current temperature.
