It is possible to set an offset (local trim) between the centre and end zone controllers.
This can be either a positive or negative difference from the centre zone temperature.
Once entered, this offset will always be added to, or subtracted from, the retransmitted
setpoint temperature.
For products with the CC-T1 controller, please refer to the separate CC-T1 controller
manual for details on how to set an offset trim.
To make this adjustment on other controllers, enter thelevel 2 menu of the end zone
controllers (see controller operating instruction), scroll to LOC.T (local trim) and use the
up down buttons to enter the desired positive or negative value. This will then be
added to, or subtract from, the end zone set temperature. There is no need to alter the
centre zone controller.
C. Independent Control
The three controllers are completely independent. Note that it is not possible to
maintain very different temperatures in the three zones because of heat transfer
between the zones. The models listed in this manual are designed to achieve an
extended uniform temperature zone by the use of three control zones rather than
achieving different temperatures in each zone.

General Operating Advice

Heating element life is shortened by overheating. Do not leave the
product at high temperature when it is not required. The maximum
temperature is shown on the product rating label and in section 10.0
towards the back of this manual.
Lightweight ceramic fibre insulation can easily be marked by accidental
contact. Some fine cracks may develop in the surface of the insulation
due to the progressive shrinkage of the insulation materials. Cracks are
not usually detrimental to the functioning or the safety of the product.
Clean up any spillages in the insulation, as these can increase the rate of degradation of
the insulation material.
4.5

Operator Safety

The ceramic materials used in the product manufacture become
electrically conductive to some extent at high temperatures. DO NOT
use any conductive tools within the product without isolating it. If a
metal work tube is used, it must be earthed (grounded).
