21.5 MAINTENANCE OF THE CIRCULATOR PUMP
For removing and/or working on the circulator pump you don’t need necessarily to
evacuate the plant circuit, just stop the fluid to flow from both upstream and
downstream sides by closing the ball valve (1) (by rotating the knob clockwise) and
closing the flow regulator valve (2) (horizontal calibration pin).
21.6 FACTORY SETTINGS OF THE CIRCULATOR PUMP
The circulator pump is already factory set for optimal operation.
The factory setting requires rotating the slot of the red knob at the blue symbol position
showing the indication of the floor plant (rotating the knob completely counter
clockwise).
It is not recommended to change this setting.

OPTIONAL DHW TECHNICAL SIDE BOILER KIT
The indoor unit in all its versions can be coupled to other external energy source in addition to the solar energy source, such as:
gas boiler, pellet boiler and any other energy source that it is implementable in the control with the characteristics of having a
proper circulator and working with a variable
∆
T without exceeding 20-25°C. The kit provides the internal pipes of connection
between the DHW technical side puffer tank and attacks disposed for the installation. The installer must provide the required
hydraulic connections for connecting the indoor unit with the auxiliary energy source as described in Paragraph 7.4.2, and control
setting as described in the manual cod. 9120523.XX.
