The B2 Magic Eye Thermostat allows precise control of any non light emitting heat source upto 600w by using advanced microprocessor technology. The Night time drop facility allows the unit to provide a different temperature to the vivarium during the hours of darkness, this provides a more natural environment for your pet. The light level sensitivity can be adjusted to suit room lighting. The B2 Magic Eye is a pulse proportional thermostat that pulses the power supplied to the heat source, for an accurate change in temperature inside the vivarium. A pulse thermostat is not suitable for light emitting heat sources as the power delivery to the heat sources would cause the bulb to flash. Recessed control adjusters are used to prevent accidental temperature changes if the unit were to be knocked, which would be easily done if the dial protruded from the casing. A yellow LED provides real time feedback as to how much power is being supplied to the heater. The Red LED alerts the user that the thermostats light sensor has detected that it is night time and has switched to night operation. Long cable lengths ensure the unit can be fitted easily into most vivarium setups.
