Thank you for choosing the Herpstat 4 digital proportional thermostat.  This product 

offers the following features: 

 

 

Four output 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).  

 

 

Outputs 1 & 2 configurable for Heating/Cooling/Lighting.  Outputs 3 & 4 can be configured for 

Heating /Cooling/Humidity/Lighting with simulated sunrise/sunset and moonlight features. 

 

 

User selectable temperature and light 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. 

 

 

Basking assist feature supports basking lights as a heat source. 

 

 

Individually selectable day/night schedules with nighttime temperature settings for each output. 

 

 

High/Low temperature tracking helps monitor heating system and enclosure efficiency. 

 

 

Individually selectable High/Low temperature threshold alarms. 

 

 

Precision temperature sensors with an internal resolution of .1125 ˚F and are accurate to ± .9 ˚F 

 

 

Display and setting in tenths of a degree. 

 

 

Security Passcode option deters vandals.   

 

 

All 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. 

 

 

Removable sensors allow for easy replacement if necessary. 

 

 

Each output is fused separately keeping an outage on one output from affecting the other. 

 

 

Audible alarm system 

 

 

Internal error detection shuts off heat if sensor fails or is disconnected. 

 

 

Internal safety relay can be configured to disable power to all outputs if user settable conditions are 

met. 

 

 

External input can be used to trigger events such as turning off a mist pump when the water supply 

is low. 

 

 

400 watt rating for each output (1600 watts total output) is sufficient for most incubators, rack 

systems, enclosures, and vivariums. 

 

 

1 year limited warranty
