CHARACTERISTICS OF THE E8 SERIES CONTROLLER:

• Boiler (boilers) temperature regulation is relative to external temperature through activation of the burner.
• Boiler inlet temperature is regulated relative to the external temperature controlled by the mixing valve actuator.
• Ability to enter two separate heating programs for each circuit (shift operation).
• Only one external sensor for up to six control levs.
• Ability to choose heating circuit functions with a classical heating circuit, a hot air heating circuit with heat exchangers, a swimming pool heating circuit, an additional sanitary water heating circuit and boiler outlet protection circuit by means of a mixing cock.
• Free choice of sensors 1k PTC or 5k NTC.
• Illuminated display of all parameters, language free choice.
• Simple programming and operation through one single button leaded by functional menu groups.
• A 4 channel weekly digital timer with 3 different periods daily per channel.
