  • Page 12: Operation Of The Pump With Adjustable Speed

    Instruction Manual The heating process for domestic water: When the water temperature sensor of the hot water tank detects that the temperature is 5°C lower than the set value (see section 5.5.2), the process of pumping water to the central heating system is stopped. The process for heating domestic water with a boiler connected to the domestic hot water tank starts as follows: •...
  • Page 13 Instruction Manual For conventional PWM pump operation (parameter P15=0) The PWM pump (activated by parameter P12) works with a modulated speed in the C.H. system activated by the signal from the room temperature regulator (RT). The rotational speed is adjusted in such a way in cooperation with the modulator to achieve the value of delta T defined by parameter P13 (the difference between outgoing and return temperature of the central heating system).
  • Page 14: Boiler Installation

    Instruction Manual 3. BOILER INSTALLATION The boiler must be installed by an authorised service company and according to local regulations. Installation of the boiler must be done so that its position is unaffected by any tension arising from increased work volumes (noise, vibrations, and stresses).
  • Page 15: Preliminary Check Activities

    Instruction Manual In case of an incorrect connection, change cords “L” and “N” in the socket. When the correct connection is detected, the boiler unlocks automatically. The X Boiler has a degree of electrical protection provided by the housing - IPX4D. In situations where the boiler is permanently connected to the power supply, the electrical installation should be equipped with a means of disconnecting the boiler from the power source, in the form of a junction box.
