1.3.1| ERC 211
ERC 211 has one relay output and two inputs
(1 analogue, 1 analogue/digital).
This controller can be used for either cooling or heating
applications.
Outputs:
– Relay 1: compressor/solenoid valve control or simple
heater in case of heating application Inputs.
Inputs:
– Input1: cabinet/control sensor (Sair).
– Input 2: condenser sensor or digital inputs which can
be configured for various functions as mentioned under
menu code o02.
1.3.2| ERC 213
ERC 213 has three relays outputs and four inputs
(2 analogues, 1 analogue/digital, 1 digital) for cooling
applications.
Outputs:
– Relay 1: compressor/solenoid valve control.
– Relay 2: can be configured either defrost or external alarm.
– Relay 3: fan control.
Inputs:
– Input 1: cabinet/control sensor (Sair).
– Input 2: defrost sensor (S5).
– Input 3 : condenser sensor (Sc) or digital input which can
be configured to various functions as mentioned under
menu code “o02”.
– Input 4: digital input which can be configured to various
functions as mentioned under menu code “o37”
1.3.3| ERC 214
ERC 214 has four relays outputs and four inputs (2 analogue,
1 analogue/digital, 1 digital) for cooling applications.
Outputs:
