FAQ:
Q: What is the difference between a rheostat and a thermostat?
A: 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.
Q: Can I use the rheostat/thermostat with a Reptisun, Avian Sun or Power Sun UV?
A: These lamps need specific line voltages; they cannot be used with dimmers/rheostats.
Q: How many heating devices can be controled with this device?
A: You can plug up to two heating devices into this temperature controller. Make sure the maximum wattage capability is not exceeded.
Q: I am using a thermostat/rheostat and the temperature is not rising.
A: 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.
