Multifunctional Thermostat URZ4055 230V Socket with External Waterproof Temperature Probe

Multifunctional Thermostat URZ4055 230V Socket with External Waterproof Temperature Probe is a plug-in temperature controller designed for automatic switching of electrical devices according to measured temperatures. The unit accepts mains 230V power and connects directly to heaters, fans, chillers or other appliances. An external waterproof probe provides reliable readings in humid or wet environments, enabling stable temperature control in aquariums, terrariums, greenhouses, utility rooms and similar applications.

Advantages

The thermostat delivers accurate temperature monitoring with straightforward setpoint adjustment and automatic ON/OFF switching, reducing manual intervention. Plug-and-play design allows for immediate installation without complex wiring, while the external waterproof probe extends measurement capability to wet or submerged locations. Built-in relay switching is suitable for many common 230V devices and helps protect connected equipment from temperature extremes.

Suitable for

• Aquariums and fish tanks
• Terrariums and reptile enclosures
• Greenhouses and seedling cabinets
• Basement, garage and utility-room temperature control
• Heating or cooling equipment such as space heaters, fans and chillers

Key specifications

• Supply voltage: 230 V AC
• Control type: ON/OFF thermostat with adjustable temperature thresholds
• Sensor: external waterproof temperature probe for wet environments
• Output: relay switch for mains-powered devices
• Installation: plug-in socket controller for easy mounting
• Operating environment: suitable for humid and indoor applications

How to use

Plug the thermostat into a standard 230V socket, connect the appliance to the thermostat output, and position the external waterproof probe where accurate temperature measurement is required. Set the desired temperature threshold according to whether you need heating or cooling control; the device will switch the connected appliance on or off when the measured temperature crosses the setpoint. Verify correct operation by observing at least one cycle of switching and adjust the setpoint if necessary.

Usage recommendations

Place the external probe away from direct contact with heating elements to avoid false readings, and secure it in the location representative of the controlled volume. For submerged or highly humid applications, ensure the probe’s waterproof sheath remains intact. Do not exceed the maximum current rating of the connected appliances; use appropriately rated devices or add an external contactor for high-power loads.
