The HELI EST electronic control thermostat from Helios is a highly advanced control system specifically designed for the operation of KTR type climate controllers. It offers a variety of control parameters and functions that enable precise regulation of room climate conditions. The dirt-resistant membrane keypad ensures user-friendly operation, while the temperature-dependent five-stage fan control guarantees optimal adjustment to current conditions. The device allows for the regulation of ventilation flaps and the control of a frequency converter as well as a heating thermostat. Additionally, it is equipped with a temperature monitor that detects under- and over-temperatures and provides outdoor temperature compensation. This control thermostat is therefore a reliable solution for the efficient regulation of air conditioning systems, ensuring a comfortable indoor climate.
