What is the difference between a rheostat and a thermostat?
A rheostat is basically a dimmer. It allows you to manually reduce the amount of power reaching a heater. A thermostat like the 500R senses the temperature and turns the heater on and off accordingly.
Can I use the rheostat/thermostat with a ReptiSun®, AvianSun™, or PowerSun™ UV?
These lamps need specific line voltages; they cannot be used with dimmers/rheostats.
How many heating devices can be controlled with this device?
You can plug up to two heating devices into this temperature controller. Make sure the maximum wattage capability is not exceeded.
What is the lowest temperature the thermostat can be set for?
Because of the applications for which this product was designed, it can not regulate or sense temperatures below about 70 degrees.
I am using a thermostat/rheostat and the temperature is not rising.
Thermostats and rheostats cannot increase the temperature a heat source is capable of putting out. Setting the thermostat/rheostat to the maximum temperature/level will be as hot as the heat source itself will get.
Can the thermostat be used in an aquarium?
While the probe is water resistant, it is designed to measure the temperature of air and may not be safe or effective for use in water.
