Correct mode of installation

for 4 zone control unit, probes and magnetic contacts

THE 4 ZONE CONTROL UNIT AND

THE PROBES

must be installed at a height of

approximately 1.5 m, away from areas

that may affect the reading of the

room temperature, such as nearby

windows, fan-coils, or radiators.

The probes may be installed both

inside standard flush-mounting, or

MAGNETIC CONTACTS

are generally installed in the upper

part of the window frames and in

the point furthest away from the

hinges. In this way small openings

cause the magnet to move away

from the contact reed and the

contact itself consequently opens.

The models in the catalogue

are of NC type and also have a

protection line generally not used

in temperature control. It is mainly

useful for preventing tampering

such as cutting the wires in burglar-

alarm systems. If the same MY HOME

system has temperature control and

burglar-alarm applications the same

magnetic contacts can be used for

both functions at the same time.

If the contact interface is correctly

congured it can support both

applications. When the temperature

control system is being installed the

protection line should be installed

and wired as well, so that the burglar-

alarm can be installed as well.

CALIBRATION OF THE 4 ZONE

CENTRAL UNIT AND THE

PROBES

The probes and the 4 zone central

unit do not normally need 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

off for at least two 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

placed inside the room.

For more details on the calibration

procedure, refer to the central unit

installation manuals.
