ENSTO ECO900 Frost Protection System
ENG
Installation and Operating Instructions
1. Introduction
The ECO900 is a device for the control of frost protection in outdoor areas, ramps, roofs and rainwater systems.
The device is intended for installation in panel boards. The device complies with the standard EN 60730.
The device accepts sensors of various kinds depending on the application.
Components for frost protection of outdoor areas (figure 1):
• ECO900 frost protection control unit (figure 3)
• ECOA901 snow and ice sensor with a heating resistor for ground installation (figure 4)
• ECOA902 humidity and temperature sensor for ground installation (figure 5)
Components for frost protection of rainwater systems (figure 2)
• ECO900 frost protection control unit (figure 3)
• ECOA903 snow and ice sensor with a heating resistor for installation in rainwater gutters (figure 6)
• ECOA904 temperature sensor for temperature measurement in rainwater gutters (figure 7)
The ECO900 frost protection control unit is supplied with an 82 kΩ resistor. An air temperature sensor ECOA904
can be installed instead of the resistor (figure 1 and 2).
To ensure proper operation the system should be taken in use before there is frost and snow. We recommend
to keep the system on for the entire heating period.
