Product description
The flush panel control TRT252-30.34, designed as ready to plug-in unit, is specifically intended for
refrigerators with complex control functions. It has two inputs for temperature sensors, five relays
and an adjustable tension exit (ventilator). The LON interface FTT10 permits communication with
super-ordinate systems.
The integrated real-time clock, however, is a special feature of this control. It is possible to adapt
the general functions and thus the gradient of the temperature in the refrigerator to the currently
needed times.
Various parameters and an additional current- and/or switching input and a external satellite tem-
perature display permit employment of the most various tasks.
Contacts of all inputs and outputs are special plug-in connectors. They are unmistakably marked
with coloured and mechanical coding, strain-free and have a lock. Complex installations and wi-
ring, therefore become redundant. Various possibilities in the organisation of the front design and
a flexible control concept create options for customer-optimised solutions which hardly set any
limits to wishes regarding service and installation comfort.
