Thank you for choosing the Herpstat
Intro+
digital proportional thermostat. This
product offers the following features:
Proportional heating constantly monitors and adjusts amount of heat necessary to maintain a target
temperature (usable range from 40˚F to 150˚F or 4˚C to 65˚C). Can also be used in non-
proportional (on/off) mode.
Built in Safety Relay on Herpstat Intro+ models to help protect against solid state failures causing
"run away" heating.
User selectable temperature ramping.
Sensor Matching allows the user to digitally calibrate the sensor output to match other equipment.
Auto Power Matching constantly adjusts the power output curve to match the enclosures efficiency.
Selectable day/night schedules with nighttime temperature setting.
High/Low temperature tracking helps monitor heating system and enclosure efficiency.
High/Low temperature threshold alarms.
Precision temperature sensor with an internal resolution of .1125 ˚F and are accurate to ± .9 ˚F
Display and setting in tenths of a degree.
Settings are retained in memory even if power is lost. *
Power Outage detection/tracking.
Temperature can be set/displayed in Fahrenheit or Celsius.
Easy to read backlit LCD display.
12ft removable sensor allow for easy replacement if necessary.
Audible alarm system.
Internal error detection shuts off heat if sensor fails or is disconnected.
Dual mounting options as a desktop or flanged mount.
Handles up to 350 watts of heating equipment.
Replaceable fuse.
5.5ft input electrical cord. 6" two prong (non-grounded) output cord.
1 year limited warranty
* Software clock is reset and features requiring the clock are disabled on power loss.
Hardware Installation
WARNING: FIRE OR ELECTRICAL SHOCK MAY RESULT FROM MISUSE. FOR INDOOR USE ONLY!
Do not exceed 350 watts.
1.
Insert the temperature probe plug into jack on the back of the Herpstat Intro+.
2.
Attach the Herpstat's power cable to a standard 120V electrical outlet.
3.
Attach the heating device to the Herpstat's AC outlet. 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. Not compatible with metal
rack systems or other setups that require grounded 3 prong cords.
Installation Tips:
Do not use aluminum tape on the probe tip.
This can cause false readings and poor regulation.
If possible, route the probe wires so that they are not in direct contact with the 120vac cables going to the
heating devices. Preferably leave at least a few inches between the probe wires and the AC lines to avoid cross
talk/electrical interference issues.
The vent holes on the back of the Herpstat provide proper cooling. Mount the Herpstat in a dry location. During
operation it is normal for the Herpstat's enclosure to be warm to the touch.
Electrical surges can often damage a thermostat. Use a good quality surge suppressor connected to the wall
outlet and plug the Herpstat into it when possible.
Setup Procedure
Note: The Enter button is used to select options while the Plus and Minus buttons are used to alter
the options or navigate the menu. If no selection is made after a period of time the unit will return
to operation automatically. While in the menu system the AC power to the output is turned off for
safety.
Press the Enter button to display the initial menu screen. This menu allows you to select the daytime
temperature, the alarm setup, optional nighttime settings, and the system setup.
Day Temp:
The Daytime Temperature setting is the temperature the device will try to maintain during the Day Cycle. If the
Nite Cycle is disabled then the Daytime Temperature setting will be used for the full 24hrs.
Alarm Setup:
Enter this menu to enable the safety alarms.
HL Alarm=OFF/ON
To Enable/Disable the High/Low Alarms press the Enter button while on this display.
HighTemp Alarm:
This setting is the highest temperature at which the audible alarm triggers if breached.
LowTemp Alarm:
This setting is the lowest temperature at which the audible alarm triggers if breached for the selected output.
Timeout=OFF/ON
(HL Alarm must be ON for this option to be enabled)
To Enable/Disable the Low Alarm Safety Timeout press the Enter button while on this display. This option is
used to add an additional safety measure should the temperature probe be dislodged from its normal position
which typically results in a "run away" heating scenario.
During initial power or after exiting the menu:
If enabled the timeout waits a 30 minute period. During this time any low alarms will not be triggered. At the
end of the timeout if the temperature has not exceeded the LowTemp Alarm setting the Herpstat will shut power
off to the heating device and display an alert message as well as beep. Pressing the Plus button will reset the
timeout for another 30 minutes. If the temperature exceeds the LowTemp Alarm setting the timeout will
automatically disable and the LowTemp alarm will function as normal.
During normal operation:
If the temperature drops below the LowTemp Alarm setting the timeout is triggered. The LowTemp alert is still
active during this scenario. Pressing the Plus button while on the temperature readout display will temporarily
mute the alarm. After the 30 minutes if the temp has not returned and exceeded the LowTemp Alarm setting
the Herpstat will shut power off to the heating device and display an alert message as well as beep. Pressing
the Plus button will reset the timeout for another 30 minutes.
