Microclimate Dimmer B1 HT Black 600W HiTemp Thermostat

The Microclimate Dimmer B1 HT Black 600W (HiTemp) is an analogue dimming thermostat built for reptile and exotic pet keepers who need reliable, smooth temperature regulation of high-output heat sources in the vivarium. Rated to 600W, it handles demanding heating setups where a simple on/off thermostat would fall short, using microprocessor-controlled dimming to gradually adjust power output rather than cutting in and out abruptly.

Dimming Control

Rather than switching the heat source on and off, the Microclimate Dimmer B1 HT varies the power supplied continuously, producing a stable, consistent temperature inside the terrarium. This smooth regulation reduces thermal stress on both the heating element and the animal, and avoids the temperature spikes and drops associated with basic on/off thermostats.

Temperature Range

Practical Design Details

• Recessed temperature control adjuster prevents accidental setting changes if the unit is knocked
• Yellow LED provides real-time feedback on how much power is currently being delivered to the heater
• 2.5m sensor cable included, giving flexibility in sensor placement within the vivarium
• External fuse socket allows quick fuse replacement without tools or disassembly
• Spare fuses included as standard

Installation and Compatibility

The long cable lengths make routing the sensor straightforward in most vivarium configurations. The unit is compatible with Microclimate's dedicated mounting bracket, sold separately, for a clean and secure installation on or near the enclosure.

For keepers running heat mats, heat cables, or other resistive heating at higher power levels, the Microclimate Dimmer B1 HT Black offers the kind of controlled, consistent performance that both the keeper and the animal can depend on.
