Therm-Control is an electronic device for adjusting Eltrace heating tape.

Power Regulator

The maintained temperature required at the heating tape can be chosen, and therefore the surface area of the pipes, within a range of 35 to 59°C (Hb 60), 35 to 72°C (Hb 70) and 35 to 58°C (Hb 55) (factory adjustment Hb 60, 59°C).

Disinfection

Once each week for 6 hours, it may be necessary to set the heating tape to maximum temperature.  The day of the week is set on the switching clock at the "disinfection" level.  Disinfection will then begin automatically on night service changeover.

Switching clock

The clock integrated into the regulator makes it possible to interrupt the operation of the heating tape once every 24 hours.  If this function is not used, leave the setting on 00.00, both for starting and stopping times.The clock has an operating capability of 12 h.

Starting current limiter

The consumption of current by heating tape depends essentially on the surface temperature of the pipe and on ambient temperature.  When the tapes are cold, in order not to draw excessively on the network, DHB 330, for a maximum of 8 minutes after each startup, limits the quantity of current consumed.  Adjustment is then free.

The performance of al the connecting and maintenance works will be entrusted exclusively to an authorized electrician.Before working on live equipment, be sure to connect the power outlet from the mains. Connection to mains by terminals L1, N and by grounding.Heating tape across terminals NN, LL and ground. 

Display

The display shows setpoint values and effective values while LEDs indicate the functions to which they refer.
