Electrical connections
Note: Do not use the ecoSTER room panel and room thermostat at the same time!
The regulator is designed to be fed with 230V~, 50Hz voltage. The electrical system should be
three core (with protective wire), and in accordance with applicable regulations. The grounding
cable should be connected to the terminals marked with the symbol
.
The connection wires should not have contact with hot surfaces (with temperature exceeding
the nominal temperature of their operation). Terminals 1–10 are intended for connection with
low voltage (<15V) devices.
Connecting mains supply 230V~ to terminals 1–10 will damage the regulator
and creates risk of an electric shock!
