Freeze Protection Thermostats
The patented and patent pending GPT–3 Freeze
Protection Thermostat is engineered to fit in between
electromechanical thermostats and high-end general
purpose single and multiple channel temperature controls.
It offers performance features that cannot be provided by
simple electromechanical thermostats while providing lower
cost and operational simplicity when compared to the highend
products. The GPT–3 is ideally suited for cost sensitive
applications that would otherwise go unmonitored.
The computerized GPT–3 has a calibrated adjustment for
setting the control temperature between 41° and 77°F (5° and
25°C). This range is ideal for freeze protection applications
without being so wide that accidental maladjustment could
prevent freeze protection.
GPT–3 features enhance heating system safety and
reliability without sacrifi cing either operational simplicity or
energy effi ciency. For example, the GPT–3 monitors heating
cables continuously so damage occurring during the summer
months is alarmed when it happens rather than waiting until
heat is needed. Both constant wattage and self-limiting
heaters are accommodated.
