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

Sensor type
This parameter denes 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 denes the desired cabinet temperature at which compressor cuts out. The set point can be locked to a range
within r02 and r03 settings.

r01
Dierential
This denes the dierence between the cut-out and the cut-in of compressor relay. Compressor relay will cut-in when the
cabinet temperature reaches the set point+ dieretial. In case of heating application, heater will cut-in when the temperature
reaches the set point-dierential.

oset
Correction value in display temperature. If the temperature of the products / cabinet and the temperature received by the
controller are not identical, an oset 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.

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.

Night setback value
The thermostat’s reference can be oset by this value during night or when there is no usage. Oset 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.
