Thermostat timer heater 600 W day/night with dual socket Exo Terra EX-4635

The Exo Terra Thermostat Timer Heater 600 W day/night with dual socket (model EX-4635) is a plug-in control unit designed to manage heating devices in terrariums and small animal enclosures. It provides pulse control to regulate a connected heater up to 600 watts and includes separate day and night timing cycles via dual switched sockets. The unit enables automated temperature scheduling by alternating on/off cycles appropriate for daytime and nighttime conditions, helping maintain stable thermal environments for reptiles, amphibians and other temperature-sensitive species.

Advantages

This thermostat timer offers integrated pulse-width control for smooth regulation of heating elements without continuous on/off cycling. The dual socket design allows two separate outputs for day and night settings, simplifying installation and reducing the need for additional timers. The plug-in form factor is compact and easy to position, and the unit is compatible with a wide range of small terrarium heaters rated up to 600 W, enabling straightforward temperature management and reduced manual intervention.

Suitable for

• Reptile terrariums requiring day/night temperature differentials
• Amphibian enclosures with scheduled heating needs
• Small mammal or invertebrate habitats where controlled heat cycles are necessary
• Use with 600 W or lower terrarium heating elements and heat mats

Key specifications

• Maximum heater power: 600 W
• Control method: pulse control for smooth output regulation
• Outputs: dual sockets for separate day and night operation
• Mounting style: plug-in, compact housing for indoor enclosure use
• Intended use: temperature scheduling for terrariums and small animal habitats

How to use

Plug the thermostat timer into a wall socket and connect the heater(s) to the appropriate day and night outputs. Configure day and night on/off cycles according to the animal species’ light and temperature requirements, ensuring the combined heater wattage does not exceed 600 W. Position the temperature probe or sensor (if provided or used separately) near the animal’s primary activity area but protected from direct contact with heating elements. Regularly verify that scheduled cycles match the enclosure’s thermal needs and adjust timing as necessary for seasonal changes or animal lifecycle stages.

Usage recommendations

Use with heaters and mats rated at or below 600 W; avoid exposure to moisture and place the unit outside of direct enclosure humidity. For accurate temperature control, pair the timer with a suitable temperature probe or thermostat probe and check enclosure temperatures with an independent thermometer. Follow manufacturer safety instructions for electrical devices and ensure cables and sockets are installed to minimize risk to animals.
