HabiStat Digital Dimming Thermostat – Day/Night Precision Temperature Control

HabiStat Digital Dimming Thermostat with Day/Night Timer (600W) provides precise, continuous control of basking lamps and other dimmable heat sources. Instead of switching fully on and off, it constantly adjusts the power to maintain a stable temperature, helping you create a safe and consistent environment for your reptiles.

This model allows separate day and night temperature settings and includes a built-in timer circuit, making it ideal for more natural 24-hour temperature and lighting cycles.

Key Features:

• Digital dimming control – supplies a continuously variable output to the heater for smooth, stable temperature control, rather than simple on/off cycling.
• Separate day and night temperatures – set independent target temperatures for daytime and night-time periods.
• Built-in timer circuit – second timed socket allows two on/off events in each 24-hour period for lighting, fans or compatible systems.
• Clear digital readout – display shows current temperature and time, plus a power meter indicating the percentage of power sent to the heater.
• Waterproof, low-voltage probe – 3 metre sensor cable for flexible, safe positioning within the enclosure.
• Adjustable temperature alarm – visual and audible alarm if the temperature moves outside your chosen high/low limits, with the option to disable the alarm if preferred.
• Memory retention – retains settings if power is disconnected.
• Maximum load 600W – suitable for one or more compatible heaters up to a combined 600 watts.

Suitable For:

The HabiStat Digital Dimming Thermostat is designed for use with dimmable heat sources, including:

• Incandescent and halogen basking lamps
• Many ceramic heaters (where the manufacturer confirms dimming control is suitable)
• Other compatible dimmable heaters within the 600W total load

Always check the heater manufacturer’s guidance and ensure the total wattage of all connected devices does not exceed 600W.

How It Works:

The thermostat measures the temperature at the probe and then adjusts the power supplied to the heater to keep the temperature close to your set point. Because it uses dimming control, it can gently increase or decrease the output rather than simply switching the heater fully on or off. This helps reduce temperature swings and can extend heater life.

The built-in Day/Night function allows you to program different target temperatures for daytime and night-time periods. In addition, the timed auxiliary socket can be used to control compatible equipment such as lighting, fans or spray systems with up to two on/off events in each 24-hour period.

Safety & Thermostat Guidance:

• Always position the probe at the correct height inside the enclosure to measure the temperature where the animal will bask or rest.
• Test and monitor temperatures for 24–48 hours before introducing animals.
• Use only good-quality, appropriately rated heaters and electrical components.
• Ensure the total connected load does not exceed 600W.
• Regularly check the probe position and cable for damage or displacement.

Frequently Asked Questions:

Is this thermostat suitable for basking lamps?
Yes. The HabiStat Digital Dimming Thermostat is ideal for controlling incandescent and halogen basking lamps, as it can smoothly increase or decrease power to maintain a stable basking temperature.

Can I set different temperatures for day and night?
Yes. You can program separate daytime and night-time temperature settings so the enclosure can run warmer during the day and cooler at night.

What is the maximum load this thermostat can control?
The maximum combined load for all connected devices is 600W. Always check the wattage of your heaters and do not exceed this limit.

Does it include a timer for lights or other equipment?
Yes. The unit includes a timed auxiliary socket that can switch compatible equipment, such as lights or fans, on and off twice within each 24-hour period.

Is the sensor waterproof?
Yes. The probe is low-voltage and waterproof with a 3 metre cable, making it suitable for typical vivarium and terrarium environments.
