Herpstat ... how do they work?

[Somed00d]

Ummm....I'm a noob.

Do those Herpstat Thermostats actually regulate the energy output to a UTH based on the reading from their probes? and can they do multiple temp settings for multiple devices (ie: power manage hot and cool side) or do you need one per target location?

Anyone? Anyone? Bueller?

Yeah they regulate the energy based on the probe temperature. Once up to temperature they hardly use any power. The only time they are at full power is when the heat tape is first warming up. They can be set for On/Off mode but why bother?

The basic Herpstat and Herpstat ND only have one probe thus temperature. The Herpstat II has 2 probes 2 outputs, herpstat pro has 4 probes 4 outputs..
