A cleverly designed Pulse Proportional Thermostat, this Habistat Thermostat is perfect for managing the heat created by non-light-emitting reptile heat sources, such as Ceramic Heaters and Heat Mats.
Rather than simply turning on/off, or varying the intensity of your heating equipment, the Habistat Pulse Proportional sends pulses of varying frequency to your ceramic heating equipment or heat mat to gradually and gently increase the temperature your reptile experiences.
Because it sends pulses, it isn't suitable for glass heat bulbs, but is perfect for non-light emitting heaters, and is one of the most popular thermostats.
Capable of handling equipment up to 600w through a single output, it features and accurate sensor to monitor your vivarium or terrarium temperature and adjusts accordingly with speed.

Sophisticated pulse proportional thermostat, ideal for controlling higher power ceramic heaters. The function of this thermostat is far more sopisticated than the simpler on/Off switching devices. It will very accurately control heaters and has a maximum load of 600 Watts. A normal thermostatswitches a heater on full power until the set temperature is achieved. It then switches the heater off completely until the temperature drops below the set value, when the cycle starts over again. The gap between the heater being switched on and then off is called hyseresis. It is between these points that the accuracy of the controller is assessed. The pulse proportional thermostat pulses electricity to the heater.
The sequence of events are as follows: The temperature is set on the dial. The cage and heater are cold so the heater are cold so the heater is on full power. As the temperature in the cage nears the set temperature the unit cuts the power down to pulses. The degree of pulse (i.e. the ammount of time the heater is on and the ammount of time it is off) is dependent on the cage temperature. In the early stages of approaching the set temperature the 'on' pulses will be long and the 'off' time will be short. In a correctly set up cage, as the desired temperature is neared, the 'on' pulses become shorter until the cycle levels at approximately 50% on and 50% off. In a cage where the only powered enough to maintain the temperature set. It does not have to continually the animals as the heater rarely, if ever, need to run at full power.
