Herpstat Digital Proportional Thermostat

Herpstat Digital Proportional Thermostat
Setting the Temperature / Night Drop
The default setting for the Herpstat is to display in Fahrenheit and is preset to 85 degrees (30˚C). To
adjust the temperature follow these steps:
Herpstat Digital Proportional Thermostat
1.
Press and hold the Adjust Temperature button until you see the progress bar indicating
that you are entering a menu. The target temperature will then be displayed.
2.
Press the + or – until the desired temperature is indicated.
3.
After 5 seconds of inactivity the progress bar will appear.
4.
The Herpstat will then display the night drop setting. This is adjustable in tenths of a degree
to a maximum of 20˚F (10˚C). If a night drop cable is not attached these settings will not
affect the operation of the Herpstat.
5.
After 5 seconds of inactivity the progress bar will appear indicating it is leaving the menu.
During this time it also saves your new settings into memory.
Checking the High / Low Temperatures
Thank you for choosing the Herpstat digital proportional thermostat. This product offers
the following features:
Herpstat will monitor the highest and lowest temperature recorded. To view these temperatures press
and hold the Display High/Low button until the progress bar is displayed and then release. Continuing
to hold the Display High/Low button after the progress bar for 5 seconds will reset the High/Low to the
current temperature.
•
Proportional heating constantly monitors and adjusts amount of heat necessary to maintain a
target temperature (Usable range from 50˚F to 140˚F or 10˚C to 60˚C). Can also be used
in non-proportional (on / off) mode

Hardware Installation
WARNING – FIRE OR ELECTRICAL SHOCK MAY RESULT FROM MISUSE.
1.
Insert the connector on the temperature probe into the jack on the top left side of the
Herpstat. If using the optional night drop cable plug it into the jack below the temperature
probe.
2.
Attach the Herpstat power plug to a standard wall outlet.
3.
Attach heating device to any of the three outlets on the Herpstat. 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 500 watts.

3.
4.
Remove power from wall outlet.
Press and Hold the – button.
Reinsert power into wall outlet with the – button depressed.
Once the display shows release the button.
Heating / Cooling
The second option is the Heating / Cooling Mode. The default setting is set for heat operations. The
cooling mode feature allows fan units or cooling devices to be used with the Herpstat instead of heating
devices. In cooling mode Herpstat uses a non-proportional ON/OFF functionality. This mode may not be
compatible with all cooling devices and is intended to be used in conjunction with emergency backup fans
for enclosures.
Proportional / Nonproportional
The third option is the Proportional / Nonproportional Mode. The default setting is for Proportional. This
option is only available if the Herpstat is set to Heat Mode. Proportional mode gives a smooth increase
or decrease in power output to the heating devices for variable heat. Nonproportional works as a
standard ON/OFF style thermostat.
Power Matching Mode (options: LOW2 LOW1 Std HI1 HI2)
The fourth option is the Power Matching Mode. The default setting is Std (standard) mode. This option
is only available if the Herpstat is set to Proportional Mode. This mode allows you to adjust the power
curve of the Herpstat to match the enclosures efficiency and better maintain the target temperature.
Sensor Matching
The Sensor Matching Menu allows users to match the Herpstat to other temperature sensing equipment.
If no change is necessary simply wait 10 seconds and the setting will be saved automatically before
Herpstat begins normal operation.
Note: The Herpstat sensor is very accurate in its default setting. Modifications in this menu are not
typically necessary.
Start by selecting the direction in which to change using the – button to toggle between R for raise or L
for lower temperature or “ 0.0” for no change. Once you have selected the direction use the + button to
set the offset adjustment. The number indicated is in tenths of a degree and will allow a maximum of 2
degrees offset. When finished, wait 10 seconds and the setting will be saved automatically before
Herpstat begins normal operation.
Understanding the Heat Output Indicator
The LED next to the display indicates the output condition of the Herpstat.
Red indicates 100% power is being applied.
Yellow indicates the temperature is close to the target temperature. Slightly less than full power is
applied to the output. (Proportional Mode Only)
Green indicates the temperature is at or very close to the target temperature. A small to medium
amount of power is applied to maintain temperature. (Proportional Mode Only)
OFF indicates no power is currently applied.

If the target temperature is set to 88 degrees Fahrenheit the Heat Output Indicator would display the
following:
Proportional Mode (Heating)
87.2˚F
Red LED
Full power.
87.3˚F
Red LED
Power is slightly reduced.
87.4˚F
Red LED
Power is slightly reduced.
87.5˚F
Yellow LED Power is slightly reduced.
87.6˚F
Yellow LED Power is slightly reduced.
87.7˚F
Yellow LED Power is slightly reduced.
87.8˚F
Green LED Power is slightly reduced.
87.9˚F
Green LED Power is slightly reduced.
88.0˚F
Green LED Power is slightly reduced.
88.1˚F
Not Lit
Power is completely off.
Nonproportional Mode (Heating)
Heat is applied until the temperature exceeds 88.5˚F.
Temperature is allowed to drop to 88.0˚F before heat is reapplied. This floating method avoids
unnecessary wear on the heating system.
Nonproportional Mode (Cooling)
If the temperature reaches 88˚F power is applied to the cooling device until the temperature drops below
87.5˚F.
Operation Tips
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.
Use the Heat Output Indicator to evaluate your enclosure’s efficiency. After an enclosure has been
operating for an hour monitor the color of the LED. If the LED is green then the enclosure is typically
well matched to the heating system. If the LED often remains or fluctuates between red and orange
then the enclosure requires additional heat to meet the target temperature. This can be done by
adjusting the Power Matching Mode.
Adjusting the Power Matching Mode to match an enclosure’s efficiency is especially important for
incubators. This setting adjusts the power output curve of the Herpstat. The settings from lowest to
highest power output are LO2 LO1 Nor HI1 HI2. Once an enclosure has stabilized watch the tenths of a
degree.
If the temperature is set for 92.5 degrees and the power output is set to Std (standard) the following
would be true:
If the temperature increases to 92.3 but never reaches the target temperature then increase the power
output to HI1 or HI2 if necessary.
If the temperature gets to the target temperature and overshoots watch the tenths of a degree closely.
When the temperature starts to drop, if it stays within that last tenth (92.4 or 92.3) and then increases
and overshoots again the power needs to be decreased. Try Lo1 or Lo2 if necessary.
If the temperature gets to the target temperature and overshoots then drops to 92.2 or lower then the
power output most likely needs to be increased. Try Hi1 or Hi2 if necessary.
Each time a change is made to the power matching mode allow another 30 minutes to regulate.
