Intelligent Water Temperature Control Switch Advantages
Adjustable Temperature Setting

The WHD-H3 uses a manual rotary knob for temperature setting. The required temperature can be adjusted directly on the unit without a digital interface.

Wide Temperature Range

The 0–320°C range provides adjustable temperature control for a broad range of heating equipment.

Automatic Reset

The standard configuration uses auto-reset. When the sensed temperature falls by the specified 2–12°C differential, the switch closes again.

Flexible Capillary Length

Capillary lengths from 300 mm to 2000 mm allow the sensing bulb to sit at the heating point while the switch housing is mounted elsewhere.

Spade Terminal Connection

The switch uses spade terminals for connection with compatible spade connectors.

Intelligent Water Temperature Control Switch Applications

The WHD-H3 is used in heating equipment that requires adjustable temperature control by a rotary knob.

Sealing machines
PPR pipe welding machines
Melting machines
Heating equipment with manual temperature adjustment
Other heating equipment requiring capillary temperature control

The final application depends on the equipment design, required temperature range, electrical rating, and installation conditions.
