Functions
Voltage protection
The voltage protection ensures that the compressor motor is operating within
safe voltage ranges. If the power supply voltage gets outside the specified
high/low voltage cut-out ranges, the compressor is cut-out or restricted from
starting. Normal compressor operation is resumed when the power supply voltage
is back in the area between the high voltage cut-out limit and the low voltage
cut-in limit. Figure 4: Voltage protection
High voltage limit
Low voltage cut-in limit (compressor start)
Low voltage cut-out limit (alarm and compressor stop)
Compressor protection
Compressor protection feature protects compressor from short ON and OFF cycles
by securing minimum run and stop time. This would allow the refrigeration
system to stabilize before starting the compressor again and also avoid the
chances of too many compressor cycles. Figure 5: Compressor protection
min run time ON
OFF min stop time time
CUT-IN
CUT-OFF time
Compressor protection against high condensing temperature
If the condenser is blocking up with dirt and thereby reaches a too high
condensing temperature, the controller will give the user early warning
through condenser alarm and if temperature rises further, it will switch the
compressor OFF. If the temperature measured by the condenser sensor (Sc) is
reaching the set “pre-alarm limit” an alarm is raised, but no further action
is taken. This is used to indicate to the user that something is wrong with
the condenser. Often the reason is that that the air flow to the condenser is
restricted (dirt) or because the condenser fan is broken. The alarm will reset
if the condenser temperature drops back by 5 °C. If the measured condenser
temperature continues to increase and reaches the set “Block limit” the
compressor is stopped, and it is restricted from starting again until the
alarm is reset manually. The alarm can be reset manually by setting the
parameter r12 Main switch to OFF position and back to ON position or by
powering the controller down.

Reference displacement
This feature enable user to toggle between two different set-points quickly by
activating a switch on digital input. This provides facility to switch between
two storage temperatures without getting in to the menu. For example meat
requires different set points than vegetables. The reference displacement
signal changes the normal thermostat set-point and the alarm limits by a
predefined reference displacement offset value (r40).

Night mode helps to reduce cooling load and thereby power consumption during
non-business hours i.e., Night time. The thermostat set point will be offset
by a fixed value during night mode keeping alarm limits same.

Defrost on Demand
This feature records the evaporator temperature when it is clean and
constantly monitors the compares that at every compressor cut outs. If the
evaporator temperature goes below the recorded temperature by the value set in
parameter d30 before the configured defrost interval, it will trigger defrost
immediately.
· This function can only be used in 1:1 systems. · This function is disabled
when the parameter “d30” is set to 20. · Defrost on demand is triggered only
if the time since the last defrost session has ended is greater than ¼ of the
defrost interval or 2 hours whichever is lesser. · Defrost doesn’t start by
this method during the following scenarios. Pull down mode Night mode Main
switch in DI or main switch in Menu is in OFF position Manual control mode
Evaporator temperature greater than 0 °C.

Applications
Pre-defined applications
The purpose of the pre-defined applications is to give the user an easy and fast way to configure the controller to a specific application based on storage temperature (LT, MT, HT), defrost type (none, natural, electrical) and defrost method (terminated on time or temperature).
When user select specific application based on their requirements, the controller will load a specific set of parameter values and will hide parameters that are not relevant for the selected application. Adjustment of the set of parameters value will be still possible at any time.
In addition to pre-defined applications, all controller versions have two standard applications, one with full list of parameters and another with simplified list of parameters, that allows the user to make their own customized parameter settings (AP0 and AP5 in case of ERC 211 and AP0 and AP6 in case of ERC 213 / ERC 214).

d02 Defrost stop temperature
0.0
This parameter defines at what temperature the defrost cycle will stop. Defrost can be stoped based on either evaporator
sensor or by the cabinet temperature sensor as defined in menu code d10.
d03 Defrost interval
0
Defines the maximum time period between the start of two defrost cycles. In case of power failure elapsed time is stored in
the memory and next defrost will happen considering the stored time interval.
d04 Maximum defrost time
0
This parameter defines the maximum time defrost will be performed. In case of temperature based defrost this is treated as
safety time to stop the defrost if it is not terminated based on the temperature.
d05 Defrost delay at power up or DI signal
0
This parameter decides the time offset when the defrost is triggered by digital inputs or during power up. This function is
only relevant if you have several refrigeration appliances or groups where you want the defrost to be staggered in relation to
one another.

Drip-off time
0
This parameter defines the time delay to start the compressor after defrost heater being switched OFF. This delay is generally
provided to ensure all water droplets on the evaporator drips off before starting the refrigeration cycle.
Fan delay after defrost
0
Defines how long the delay is between the start of the compressor and the fan after defrost cycle. This would help to avoid
hot air circulation in the cabinet imedietely after defrost.
Fan start temperature after defrost This only applies if an evaporator temperature sensor is fitted. This parameter determines at what evaporator temperature the fan will start after a defrost cycle is complete. If the time set in d07 occurs before the temperature set in d08, the fan will start in line with d07. If the temperature set in d08 occurs first, then the fan will start in line with d08.

This parameter is to define whether fan is to operate during defrost or not.
Defrost Stop Sensor
non
This parameter is to define which sensor has to be used to exit / terminate the defrost
non = none, defrost is based on time
Air = Sair sensor
dEF = S5 defrost sensor
Compressor accumulated runtime to start defrost
0
When the accumulated compressor runtime is equal to the value set in this Parameter, defrost will be triggered. If the accu-
mulated compressor runtime is less than the set value during the defined defrost interval (d03), defrost will be triggered
based on the defrost interval (d03). This feature is disabled when this parameter is set to zero.
Defrost on demand
0.0
The controller will record S5 temperature during each defrost interval when the evaporator is clean and continue to monitor
S5 temperature. Controller triggers defrost if the S5 temperature becomes less than recorded temperature by this value it will
initiate the defrost on demand. This feature is disabled when this parameter is set to 20. This function can only be used in 1:1
systems.
Defrost delay after pull down
0
This parameter defines the time delay to start the defrost after pull down cycle. This has to ensure defrost doesnot happen
immedietely after pull down cycle.
