Security Setup
From the initial menu screen select Security using the Plus and Minus button and press Enter.
This setting creates a 4-digit Passcode that is required to be entered before menu access is granted. Use the
Plus and Minus buttons to toggle the individual digit and the Enter button to advance to the next digit. Entering
all zero's will disable the Passcode. If the menu timeout expires while in this setting the Passcode will be
disabled automatically. If you forget this Passcode in order to regain access to the menu requires the device to
be reset to factory defaults. This can be done by holding down the Plus button while plugging the Herpstat 4
into power. All settings are lost in this process.
Hardware Setup
(menu option)
From the initial menu screen select Hardware using the Plus and Minus button and press Enter.
Test HW:
This option will run through a hardware test. Incandescent lamps should be plugged into the outputs to verify
power is being turned on and off. The unit will briefly turn on and off each output while displaying which output
its working with on the lcd. Check to make sure the corresponding lamp turns on and off. The next test will
check to make sure the internal clock is advancing properly. Should it fail any of these, contact support and
stop using the device.
ExtInp Menu:
Enter this menu to Enable/Disable the External Input and select the action to take place. The External Input is
designed to attach to a non-powered switch wired by the user. It uses a standard 3.5mm mono plug.
Trigger:
This setting determines what type of trigger will activate the External Input event. In OPEN Contact mode the
event will trigger if a switch is in its open state (not conducting). In Closed Contact mode the event will trigger
if a switch is in its closed state (conducting). While in this setting the Herpstat 4 will display the current status
of the External Input to help you choose.
Action:
This setting determines what action will take place when the External Input event gets triggered.
Options:
Audible Alarm
This option will provide a audible alarm every few seconds during an External Input event.
Alarm & Shutdown
This option will provide a audible alarm every few seconds and power off all outputs and activate the safety
relay during a External Input event.
Power OFF Output 3 Only
Power OFF Output 4 Only
Power OFF Output 3&4 Only
Power ON Output 3 Only
Power ON Output 4 Only
Power ON Output 3&4 Only
These options turn ON/OFF the #3 & #4 outputs which can be used to keep misting pumps from running dry,
powering an alarm, etc.

Safety:
This setting determines what course of action will take place during an error condition. This also controls the
built in safety relay. Once the error condition is corrected the device will return to normal operations.
Options:
INDIVIDUAL OUTPUTS: Excludes High / Low
This option is the default setting and does not enable the built in safety relay. During an error condition it turns
off the output that has the error. High/Low alarms will not shut off the output.
INDIVIDUAL OUTPUTS: Includes High / Low
This option does not enable the built in safety relay. During an error condition it turns off the output that has
the error. High/Low alarms will shut off the output.
ALL OUTPUTS IF: Any Error
This option enables the built in safety relay. If any error condition occurs all outputs will be turned off and the
safety relay is triggered, which cuts the main power to all the outputs.
ALL OUTPUTS IF: High/Low Error
This option enables the built in safety relay. If any High/Low alarm condition is set and is breached all outputs
will be turned off and the safety relay is triggered, which cuts the main power to all the outputs.
ALL OUTPUTS IF: Low Alarm Error
This option enables the built in safety relay. If any Low alarm condition is set and is breached all outputs will be
turned off and the safety relay is triggered, which cuts the main power to all the outputs.
ALL OUTPUTS IF: High Alarm Error
This option enables the built in safety relay. If any High alarm condition is set and is breached all outputs will
be turned off and the safety relay is triggered, which cuts the main power to all the outputs.
The Display
In normal operation the Minus button will toggle between the available display while the Plus button will activate
special features of that display. Then the Enter button will activate the menu system.
Temperature / Humidity Probe Status & Power Output
This display shows the current temperatures and humidity levels from attached probes. It will also indicate if an
output is disabled or set to lighting mode. For each output it will show the amount of power being applied. If
an error occurs a description will be shown instead of the output information. The setting the device is trying to
achieve is in parentheses. When ramping is enabled for temperature the value in parentheses will change
according to the time based curve.
Special Symbols:
Next to the number of the output an arrow symbol will appear if that output is currently in a ramping session. A
right arrow (
→
) will appear if the ramp is increasing. A left arrow (
←
)
will appear if the ramp is decreasing.
Next to the number of the output a minus sign (
-
) will appear if a Low Alarm has been breached. A plus sign
(
+
) will appear if a High Alarm has been breached.
High Low Status
This display indicates the highest and lowest temperature/humidity level recorded for the probe and the time at
which it was recorded. Pressing the + button will reset the High/Low to the current reading.
