HT 20 – Directions for Use

The regulator HT 20 is an electronic PD-regulator with a 7-pole flange socket with integrated

temperature sensor socket. This is important, when the heating must often be separated from the

regulator, especially by non-professionals. The HT 20 is incapsulated hermetically in a plastic

case. An integrated mains switch make it possible to connect the regulator directly to the mains.

To guarantee a safe switching-off, the regulator has a double-pole switching relay with contact

clearance >= 3 mm.

Types for thermo-couple have an integrated cold junction compensation.
