    Learn about the product

    EFIT 850 microprocessor controller is fully automatic, digital electronic device. Its operation is based on complex digital measurements provided by temperature and humidity measuring sensors. Simultaneous moisture and temperature measuring allows controller to save up to 75% energy comparing with systems that provide temperature measurements only.

    Digital sensors provide much higher accuracy than analog ones. As a result frost protection system operated by EFIT 850 provides higher level of functionality and lower operating costs. Therefore we recommend using this type of thermostat for installations with output capacity exceeding 5 kW or for any smaller installations where optimum power use is a preference.

    Configuration options

    EFIT 850 can control two independent installations with maximum 4 sensors connected in various configurations, i.e. two independent systems or two zones in one system with separate outputs.

    In addition, priority setting for both zones is possible. You can set one zone for the higher priority and another for the lower priority.

    The zone with lower priority will be activated following switching off the zone with higher priority. In this way you can reduce demand of the available power for the frost protection system.

    Intuitive menu of the thermostat allows simple settings. For detailed instructions and data specifications please refer to the safety data catalog and installation manuals for corresponding sensors and controllers.

    Note: When connecting more than two sensors additional power supply is required.

    Energy consumption

    Сontrol of several parameters has an effect on energy consumption. No energy is consumed in cold dry weather – usage of moisture sensors is important and enables switching the system off in cold dry days, so no excessive energy is consumed.

    Less energy consumption in case of system splitting into zones with different weather impact – splitting area into 2 zones, e.g. North and South, allows saving energy when the southern side is free of ice and snow melting runs faster by the sun heat.
