AT1-5
Refrigeration Controller Positive Cooling / OEM
The AT1-5 series comprises cost-effective refrigeration controllers with heating or cooling functions and a high-power relay up to max. 16A (heating) and 8A (inductive compressor switching capacity).
Its strengths lie in its simple configuration, self-explanatory membrane keypad, an INFO menu with essential information, and a door contact switch.
The second output’s function can be freely selected and triggered, for example, via the I/O button or, for lighting control, via the M button.
