Circulation pump
When programming the operating mode of the circulation pumps is not necessary to
connect any special congurators: it will be sucient to use the temperature central
unit. Through the “Pump” item, inside the “Maintenance” menu, select the zones that
must be served by a circulation pump. Using the programming procedure, set a logic
link between the zones, and the pump that hydraulically supplies them. To complete
the programming procedure, the pump management mode must also be selected, thus
dening if the pump supplies a heating, a cooling, or a combined system. Depending on
the needs of the hydraulic system, one “circulation pump” or “several circulation pumps”
may be installed, to supply one or more zone groups. If necessary, it is also possible to set
a “pump switch-on delay”, in relation to the opening of the zone valves.
In the following cases, pump control is not necessary:
- in systems where the pump is always in operation (thanks to water recirculation
hydraulic systems, or the presence of three-way valves);
- in systems where the pump is managed automatically (it comes on by itself when
water is required, and turns o again when all valves are closed);
- in systems where the pump has simply not been installed (for example for air
conditioning units or electric heating control).
Probe calibration
Probes don’t normally require calibration; however, in particular installation situations
(perimeter walls, north or south facing walls, when close to heat sources, etc.), the
temperature value measured may be corrected using the appropriate calibration
function, which can be found in the central unit menu.
Before performing the calibration operation, ensure the following:
• leave the probes connected and powered with the hydraulic system o for at least 2
hours. During this time, avoid any changes in the room temperature (e.g. by opening
or closing windows, doors, etc.), and avoid standing near them;
• for the calibration use a calibrated sample thermometer, correctly positioned inside
the room.
Note: For more details on the calibration procedure and the programming operations
using the central unit, refer to the installation manual of the central unit.
