TEMP UNITS:
°
F
This prompt indicates that Zolar is currently configured to display all temperatures degrees Fahrenheit. Use the
+/Yes
or
-/No
keys to toggle between the °F and °C format. Once the desired units are displayed, press the
Next
key to save
the temperature format and proceed to the next item in Configuration Menu.
START WEEP #1:
°
F 34
This prompt indicates that the Weep #1 Output will start cycling at 34°F. This output is controlled by the lower of the
temperatures indicated by Sensor #1 and Sensor #2 (if configured for Dual-Temp Weep). Fail-Safe reasons the Weep
Output relays are normally energized when it is warm and de-energized when it is cold. Also, for Fail-Safe reasons, we
recommend using the N.O. relay contacts to drive a N.O. solenoid valve for the weep system. In this manner, if power
fails or a wire is broken, the weep water will flow and prevent freezing of the high pressure hoses and wands. The Start
Weep set point controls the temperature at which "weep cycling" of the output begins. The Start Weep set point can be
adjusted in one-degree steps by using the
+/Yes
and
-/No
keys. The
Next
key will save the new value and advance the
menu to the Full Weep message.
FULL WEEP #1:
°
F 15
This prompt indicates the temperature at which "weep cycling" becomes 100%. At this temperature and below, the
associated Weep Output relay will always be turned off so that the N.O. solenoid valve will be open providing weep
water to prevent freezing of the high pressure hoses and wands. At temperatures between Start Weep and Full Weep,
the Weep Output relay will energize for only a percentage of each minute in proportion to the proximity of the sensed
temperature to the Start Weep and Full Weep set points as detailed in the diagram on page 2. In the example using Start
Weep = 34°F and Full Weep = 15°F, if the sensed temperature is 20°F then we would be 5° from Full Weep out of a
total of 19° between Start Weep and Full Weep. Since at Start Weep the relay is On 100% of the time, then at 20°F the
relay would be On 5/19 = 26.3% of the time during each minute, for a period of 16 seconds each minute. As with the
Start Weep set point, this set point can be adjusted in one-degree steps by using the
+/Yes
and
-/No
keys. The
Next
key will save the new value and advance to the next item in Configuration Menu.
AUX #1 TYPE: TEMP
The equipment connected to the Aux #1 output can be controlled based on time, temperature or ambient light intensity.
The above message indicates that Zolar is currently configured to control the Aux #1 Output based on having a
Temperature Probe connected to the Sensor #2 terminals. If this is not the desired configuration, use the
+/Yes
or
-/No
key to select either LIGHT or TIME.
¾
If
TEMP
is selected, the next prompt displays a temperature set point:
TEMP TRIP: °F 34
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.
AUX #1 ON IF COLD
This prompt indicates that the Aux #1 Output relay will be energized on temperatures below the Temp Trip
setting This example setting would be useful to control a pump circulate antifreeze solution in pipes embedded
in a concrete slab. When controlling Aux Outputs by temperature, Zolar uses 2°F of hysteresis to prevent
indecisive behavior near the set point. In this example Aux #1 Output will turn Off when the temperature rises
to 36°F. You can change the setting to On If Hot by using the
+/Yes
and
-/No
keys. The
Next
key will save
the new value and advance the menu to the next item.
