We are often asked about a solution for room heating or cooling control. In the past we have recommended other brand industrial relay based controllers for this solution. One of the complaints was the lack of features with those controllers and their reliability. Our answer to this is the new Herpstat HP (High Power). This non-proportional relay based thermostat was designed primarily for oil filled space heater control. What sets this unit apart from other brands? We included our safety relay feature so there is a backup component that can cut power should the primary power relay stick in the ON position. Previously people had to use two thermostats inline for this type of protection. We also have added additional sense circuitry that helps limit the electrical arc that wears relay contacts often resulting in 2 to 3 times longer relay contact life than other brand thermsotats. This unit can be used for heating, or cooling, or humidity control(with the optional humidity probe). We have built in many of the typical Herpstat features such as High/Low tracking, built in adjustable night time temperature, ramping of temperature over time, audible alerts, and more. The Herpstat HP comes in a wall mountable enclosure and includes a temperature probe with a 12 ft cord making it easy to find the right location to monitor your room temperature. Power control is rated at 12.5 amps or 1500 watts.
This unit is specifically designed for room heating (oil filled heaters), cooling (box fans), or humidity. This unit is not recommended for rack or cage temperature control.
