PROGRAMiNG
The ERC-2 control initially powers up displaying 12:00 AM otherwise
it will show the last configured selection (time or temperature).
If a power outage occurs during normal operation, the control will
maintain the correct time-of-day using a capacitor (batteries are not
required). The time will be maintained for up to 100 hours when the
capacitor is fully charged.
To initiate a
Manual Defrost
, press and hold the MAN DEF key for
3 seconds.
There are two levels of programming in the ERC-2. The first level of
security will enable the user to set two parameters: Time-of-day (
CloC
)
and Setpoint temperature (
SEt
). The other level allows access to the
other parameters.
Three buttons are used for the programming: SET, UP and DOwN
Figure. 13 – Display layout
To change Time-Of-Day and Setpoint temperature (First level) follow these steps:
Step 1
Press and hold set for 5 seconds. The display will show
CloC.
Step 2
Press SET again to change the time-of-day.
Step 3
or
Press UP or DOwN until the correct time-of-day is displayed.
Step 4
Press SET to accept the new time.
Step 5
Press DOwN to go to the next parameter – Setpoint Temperature -
SEt
(cut out).
Step 6
Press SET to change the setpoint temperature.
Step 7
or
Press UP or DOwN to go to the desired setpoint. The range is – 40° to 60°F or –40° to 16°C.
Step 8
Press SET to accept the change.
Step 9
Press DOwN to exit the first level of programming.
Note 1:
During programming, if no button is pushed during 30 seconds, the control will go back to the normal operating mode.
This is valid for both programming levels.
Note 2:
when changing the time, press and hold the MAN DEF button for 3 seconds to change the AM/PM mode.
To change the other parameters (Second level) follow these steps:
Step 1
or
Press and hold SET and DOwN for 10 seconds. The display will show
dSPl.
Step 2
Press SET to change the parameter.
Step 3
or
Press UP or DOwN to change the options, time or temperature for the current parameter.
Step 4
Press SET to accept the new value.
Step 5
Press DOwN to go to the next parameter, then go back to Step 2. After the last parameter
is displayed (
Alhi
), the display will go back to the normal operating condition.
Note:
To scroll down the parameters without changing them, press the DOwN button.
