HabiStat Pulse Thermostat 600W HabiStat Pulse Thermostat 600W – The Habistat Pulse Thermostat, ideal for controlling higher power ceramic heaters and for heat mats. A normal thermostat switches a heater on full power until you achieve the set temperature. 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 hysteresis. It is between these points that accesses accuracy of the controller. The pulse proportional thermostat pulses electricity to the heater all the time. This results in constant and very accurately managed warmth. Available in standard and day/night versions in either black or white. All Habistat thermostats also come with a 5 year guarantee.
