7.3.2 Use of adjustment devices
The use of an adjustment device is not permitted for the
Easy controllers. Depending on the delivery period and
factory preparation, the values displayed on the control
component cannot be clearly assigned as for the orig-
inal equipment or for substitute controllers.
7.3.3 Adjustments sticker
The adjustments sticker documents the factory testing,
the settings and the most important order data of the
VAV terminal unit and the control component.
Fig. 24: Adjustments sticker
The information is required as part of the technical sup-
port provided by the TROX service or for the ordering of
replacement parts.
7.3.4 Ordering replacement controllers
The device type and nominal width/dimensions are
required to order an Easy replacement controller. Cus-
tomer-specific operating values for Easy controllers are
not set at the factory. The information can be found, for
example, on the adjustments sticker described in the
previous chapter.
Example of order information: replacement Easy type
controller for VAV terminal unit TZ-SILENZIO in dimen-
sion 200: TZ-SILENZIO 200 / Easy
Note:
for some VAV terminal unit types, Easy replace-
ment controllers can be used regardless of the dimen-
sions of the basic units.
This only applies to types TVR, TVJ, TVT, TVZ.
Examples:
a replacement controller for the TVJ/Easy
type can be used both on the nominal width of 300x100
and on all other dimensions of the TVJ. A TVR/Easy
type replacement controller can be used on the 250
nominal width, as well as all other dimensions of the
TVR.
