Microclimate Dimmer B1 Thermostat Black 600w

The Microclimate Dimmer B1 Black is a 600W dimming thermostat designed for reptile keepers who need reliable, accurate temperature control in their vivarium. Rather than switching heat on and off, it gradually varies the power supplied to the heat source, delivering smooth, stable temperatures that better reflect natural conditions.

How It Controls Temperature

Using microprocessor-based dimming technology, the B1 continuously adjusts power output rather than cycling the heater on and off. This gradual approach reduces temperature fluctuation inside the vivarium and is gentler on heat sources over time.

Designed to Prevent Accidental Changes

The temperature control adjuster is recessed into the casing rather than protruding outward. This deliberate design choice means the dial is protected from accidental knocks — an important consideration when the thermostat is positioned in or around an active vivarium setup.

At-a-Glance Power Feedback

A yellow LED indicator provides real-time visual feedback on how much power is currently being delivered to the heat source. At a glance, you can see whether the thermostat is working hard or barely running — useful for monitoring seasonal changes or identifying issues early.
