DFM
NON;
TIM;

RTC
Defrost start mode (NON)
NON : defrost function is disabled (the following parameter will be FCM).
TIM : regular time defrost.
FRO : the defrost time count is only increased when the conditions occur for frost to form on the evaporator (optimised
time increase). If the evaporator works at 0°C, defrost frequency depends on the thermal load and climatic conditions. With
setpoints much lower than 0°C, defrost frequency mainly depends on the refrigerator operating time.
RTC : the defrost time is scheduled by parameters DH1, DH2, ...DH6.
DFT
0...99 hours
Time interval among defrosts. When this time has elapsed since the last defrost, a new defrost cycle is started.
For example, with =TIM and =06, a defrost will take place every 6 hours .DFM DFT (06)
DFB
NO/YES
Defrost timer backup. With DFB=YES, after a power interruption, the timer resumes the count from where it was left off with
±30 min. approximation. With DFB=NO, after a power interruption, the defrost timer will re-start to count from zero ( .NO)
DH1
...

differential. (Te = Evaporator temperature, Ta = Air
temperature);
TIM : Timed-based control. The fans are ON when
the compressor is ON. When the compressor is
OFF, the fans switch ON and OFF according to
parameteres FT1, FT2, FT3 (See Fig.2).

1. INSTALLATION
■The BR1-28 controller, size mm (WxHxD), is to be secured to a DIN rail in such a position as to ensure that no liquid infiltrates causing serious 107x95x47
damage and compromising safety.
■Make sure that electrical connections comply with the paragraph “wiring diagrams”. To reduce the effects of electromagnetic disturbance, keep the
sensor and signal cables well separate from the power wires.
■Place the probe T1 inside the room in a point that truly represents the temperature of the stored product.
■Place the probe T2 on the evaporator where there is the maximum formation of frost.
■The function of probe T3 is determined by the parameter T3. With =DSP the probe measures the temperature to be displayed. With =CND the probe T3 T3
measures the condenser temperature, it must therefore be placed between the fins of the condensing unit. With =2EU the probe measures the temperature T3
of the second evaporator and it must therefore be placed where there is the maximum formation of frost. With =NON, the third probe is disabled.T3
■At the first power-up or after a long power failure, the display might show “TIM”: press any of the buttons to mute the buzzer, then check if the real time
clock is correct (MIN, HRS).

Resuming thermostatic cycle. When defrost is over, if is greater than 0, all outputs will remain off for minutes, in order for the ice to melt DRN DRN
completely and the resulting water to drain. Moreover, if probe T2 is active (T2=YES), the fans will re-start when the evaporator gets to a temperature lower
than FDD; Vice versa, if probe T2 is not active ( =NO) or after defrost has come to an end, such condition does not occur by end of the time , after T2 FTO FTO
minutes have elapsed the fans will be switched on anyway.
Caution: if =NON or =HEA all defrost functions are inhibited; if =0, automatic defrost functions are excluded. During defrost, high temperature DFM C-H DFT
alarm is bypassed.
