Hardware Installation

WARNING – FIRE OR ELECTRICAL SHOCK MAY RESULT FROM MISUSE. For INDOOR USE ONLY!

1.

Insert the connector on the temperature probe into the jack on the top left side of the Herpstat ND.

2. Attach the Herpstat ND power plug to a standard wall outlet.

3. Attach heating device to any of the three outlets on the Herpstat ND. These devices may include heat

tape, heat coils, mats or other resistive load heating devices. Not recommended for use with rock
heating devices or other devices that come in direct contact with the animal. In cooling mode the
outlets can be used for emergency fans. Do not exceed 600 Watts (400 Watt on 240V models).

Configure Menu

Adjustments: Display Type, Mode, Coil Warmer, Power Matching, Sen sor Matching,
NiteDrop Start Time, NightDrop End Time, SetClock, Alarm Clock

When first powered on the Herpstat ND will display the temperature probe status. To enter the Configure Menu
press the + Menu button (this menu only is available from the probe status screen. Use the – Display button to
navigate to it if necessary). The display will show two options:

+ Setup

- Config

Press the - button to enter the Configure Menu. While in the Configure Menu the Herpstat ND will toggle to the
next option after 5 seconds of inactivity and will return to normal operation once all options have been displayed.
While in the Configure Menu the output is disabled.

Display Type

Options: Celsius/Fahrenheit
The default setting is to display temperature in Fahrenheit. After changing display modes the target temperature,
night drop amount, temperature thresholds, and the sensor matching setting will be reset to the default setting.

Mode

Options: Proportional / Non-Proportional / Cooling

The default setting is for Proportional. Proportional mode varies the power output to the heating device as
necessary to maintain the target temperature. Non-proportional works as a standard ON/OFF style thermostat.
Cooling function allows the attachment of emergency fans and functions as a non-proportional output.

Coil Warmer

Options: ON / OFF

This option is used for incubators that have a coil heating element and is only available in proportional mode. In
testing one of the biggest problems with coil heat elements is the startup time it takes to warm the coil during
regulation. Turning this feature on will keep a small amount of power applied to the coil for a few tenths of a
degree over the target temperature. This limited amount of power usually is not enough to raise the temperature
of the environment but keeps the coil warm so that it can regulate faster once the temperature drops.

Power Matching

Options: Normal / High1 / High 2 / High 3 / Low1 / Low2 / Low 3 / Auto

This option is only available if the output is set to Proportional Mode. The default setting is Auto. This mode
allows you to adjust the power curve of the Herpstat ND to match the enclosures efficiency and better maintain
the target temperature. Auto will adjust the power curve automatically.

Sensor Matching

This option allows users to match the Herpstat ND to other temperature sensing equipment. Use the + and –
buttons to adjust the offset.

Note: The Herpstat ND sensor is very accurate in its default setting. Modifications in this menu are not typically
necessary.

NiteDrop Start Time

This is the time the day cycle will end and the night time cycle will begin.

NiteDrop End Time

This is the time the night cycle will end and the day cycle will begin.

SetClock

Adjusts the internal clock’s time.

Alarm Clock

The alarm clock feature allows the Herpstat ND to give an audible beep sequence just like a standard alarm clock.
Pushing either button will stop the alarm.

Setup Menu

Adjustments: Temperature, Night Drop Temp, High / Low Th reshold Alarms

When first powered on the Herpstat ND will display the temperature probe status. To enter the Setup Menu press
the + button (this menu only is available from the probe status screen. Use the – Display button to navigate to it
if necessary). The display will show two options:

+ Setup

- Config

Press the + button again to enter the Setup Menu. While in the Setup Menu the Herpstat ND will toggle to the
next setting after 5 seconds of inactivity and will return to normal operation. While in the Setup Menu the output
is disabled.

Day Temp

This is the desired temperature during daytime hours. Default setting is 85˚F or 30˚C.

NiteDrop

This is the amount of degrees you would like to drop during night time hours. For incubators or other
environments that do not require this feature set it to DISABLED. This option is adjustable in tenths of a degree
up to 50.0˚F or 20.0˚C. If set to PWR OFF the output will be completely turned off during the night cycle.

Example: If your day time temperature is set to 88˚F and at night you would like it to drop to 82˚F then you
would set the NiteDrop to 6.0 (88˚F – 6˚F = 82˚F).

H-Alarm L-Alarm

The temperature threshold alarm feature of the Herpstat ND is adjustable from .5 to 10 degrees in tenths of a
degree increments. This feature should not be set until the environment has reached its standard operating
temperature. Once set, if the temperature exceeds or drops below the threshold the Herpstat ND will sound an
audible alarm and will display a + or – next to the temperature depending on which alarm was breached.
Pressing either button will mute the alarm for 5 minutes. The alarm will still display on the screen.

Example: An incubator set with a standard temperature of 88 degrees, H-Alarm set for .5 degrees and L-Alarm
set for 1 Degree. If the heating coil fails and the temperature reaches 87.5 or below an audible alarm will sound.
Also, should the heat raise to 88.5 or above the audible alert will sound.

If the night drop option is activated there will be a between time when the environment is changing from the day
temperature to the night temperature or night to day. From the time the NiteDrop is activated or deactivated the
H-Alarm and L-Alarm will be disabled for 15 minutes to allow the environment to stabilize. At that point they will
return to normal operation. If the night drop is set to PWR OFF the alarms will be disabled during the night cycle.

Tip: Most environments have a degree sway unless it’s a well insulated incubator with a properly set Power
Matching setting. Monitor your environment before using this feature to determine the most realistic setting.

The Display

Options: Temperature Probe Status & Power Output / High Low Status / Power Outage Monitor

Internal Clock

Use the – button to toggle between displays. Use the + button to enter a menu or set options.

Temperature Probe Status & Power Output

Shows the current temperature from the attached probe and the amount of power being applied to the output.

High Low Status

Displays the highest and lowest temperature recorded. Pressing the + button will reset the
High / Low temperatures to the current temperature.

Power Outage Monitor

Each time the Herpstat ND is powered on it increments this monitor. To reset the monitor to zero press the +
button.

Internal Clock

Displays the current time and also displays the current day / night cycle determined by the Night Drop
Start / End times.

APM (Auto Power Matching)

When the Power Matching mode is set to Auto this screen will be available. Shows the current power matching
mode that the thermostat has switched to. Every three minutes the thermostat will check and adjust this setting
as necessary.

Getting the most out of your Herpstat ND

When setting up a new environment allow a minimum of one hour for the temperature to stabilize. Keep in mind
that all items in the enclosure are warming up including the enclosure walls. Probe placement may require
experimentation to achieve proper temperature regulation.
