The LRTC Pro II is the classic in the terrarium and still cheaper to get than in local "pet shops" where he loosely times 80 costs. Have him now for over 6 weeks at my boa constrictor imperator in conjunction with a 60W Elstein in use and am very satisfied. From an unwanted adjustment of the time I have so far can not see anything. Some old models had earlier this problem. The temperature can also be easily adjusted as all the other parameters and it can be set for 2 units both arrival and out. Thus, no other switches are no longer necessary in a terrarium with a maximum of 2 electrically controlled lamps or heaters. The temperature is maintained well and by switching delay can be as much as possible natural fluctuations insert because in nature is the temperature also not always the same. Switching delay means that eg the heater is based on reaching 28 degrees (set day temperature) and the terrarium thus cools. It has now been 2 degrees switching delay can set the thermostat, the temperature drop only to 26 degrees before the heater comes back on. So you get back I mentioned the temperature fluctuations. If there is something colder in the winter in the room, it is advisable to downsize or to set the day and night value or 2 degrees higher the switching delay. Note: The thermostat is of course on the temperature of the sensor (sensor) measures. If this so sits directly under the lamp, the temperature is reached very quickly and the heater goes off. Thus, the temperature in the remaining part of the terrarium is no longer correct. I have placed the sensor in my approximately centrally on the floor. Thus do I control the minimum temperature in this area. The terrarium should not be equally warm everywhere. Take definitely time for voting and measures the temperature by hand thermometer (better by infrared laser thermometer), and describes it as a that it fits.
