Does anyone know how a reptile thermostat works? I gather that you plug different heating sources into it, but does it just randomly turn on and off different lights at various times to maintain the preselected temperature? Can they work in conjuction with a timer to maintain both day and night temperatures? Will it know to only turn on daytime lights during the day and nighttime lights during the night? I am only curious because my house was built by a solar engineer and it sucks in a lot of heat during sunny days, which makes it hard to maintain a given temp. Sometimes, at night my cages will be only 80 and sometimes 90, it just depends on how hot that day has been. Any advice? Thanks!
