1 - DESCRIPTION B4U
1.1 - GENERAL DESCRIPTION
The B4U model is an intuitive control panel that combines the Display
B4U (Display) plus the Power Unit B4U (power unit). It has a digital
microprocessor that can be used for temperature control in
refrigeration applications. It is prepared for the ON / OFF control and
defrost control, at intervals of time, to reach the temperature or for
the continuous operation of the compressor through the compressor
stop, electrical resistance or gas inversion / hot cycle.
The B4U has special functions to optimize defrost and functions that
can be used to achieve energy savings in the system.
The B4U has up to 4 relay outputs and 5 configurable inputs, of which
3 are for NTC temperature probes and 2 are digital for voltage-free
contacts.

Going from the Stand-By state to the ON state is exactly the same as turning on the B4U with the power supply. In case of power failure, the B4U returns to the function that was just before the power supply interruption. - Page 6 - Exiting ECONOMIC mode (only if "HC" = C3) increase (parameter "du") and for the decrease (parameter "dd") and - Every time the B4U is started (only if "HC" = C3 and Pr1 greater thus avoid showing a rapid change in temperature.
