Thermostat gets a warm reception

Using a trace heater with integral frost thermostat from ATC Semitec can help eliminate problems associated with freezing temperatures in water and boiler condensate pipes. Matsuo MQT frost thermostats are said to be simple to integrate and give 10 times the life of conventional disc thermostats. They can be calibrated as low as -10°C and the differential, or hysteresis, can be as small as 3K. Thus the MQT thermostat is designed to provide long-term accurate frost protection and minimal energy consumption.
