Predefined applications
Predefined applications is to give the user an easy and fast way to configure the controller. Users can set appropriate applica-
tion that meets their requirements under this menu (please refer predefined applications table under section 2.4 for more
details). Predefined application is protected by main switch.

Sensor type
This parameter defines the type of temperature sensors connected to the controller. Below sensor types can be used in
ERC21x
n5=NTC 5K (5000 Ohm at 25 °C, Beta value=3980 @25/100 °C)
n10= NTC 10 (10000 Ohm at 25 °C, Beta value = 3435 @ 25/100 °C)
pt1= PT1000
ptc= PTC
All the mounted sensors (Sair, S5 and Sc)must be of same type.

SetPoint
This parameter defines the desired cabinet temperature at which compressor cuts out. The set point can be locked to a range
within r02 and r03 settings.

r01
Differential
This defines the difference between the cut-out and the cut-in of compressor relay. Compressor relay will cut-in when the
cabinet temperature reaches the set point+ differetial. In case of heating application, heater will cut-in when the temperature
reaches the set point-differential.

Display offset
Correction value in display temperature. If the temperature of the products / cabinet and the temperature received by the
controller are not identical, an offset adjustment of the display temperature can be carried out using this parameter.

Display Unit
Set here if the controller is to show temperature values in °C or in °F. Switching from one to the other will cause all tempera-
ture settings to be automatically updated to respective unit.

r09
Calibration of Sair
This parameter is a relative value and allows adjustment of the Sair sensor temperature. For instance, at a measured tempera-
ture of 7 °C and r09 set to 2K, the input from the Sair sensor will be 9 °C instead.

Main Switch
With this setting refrigeration can be started, stopped or a manual override of the outputs can be allowed. Stopped refrigera-
tion will give a “OFF” signal on the display.

Night setback value
The thermostat’s reference can be offset by this value during night or when there is no usage. Offset can be set both possitive
and negative sides (Select a negative value if there is to be cold accumulation). Activation can take place via digital input.
