The terminals in the middle are used to change the
voltage of the unit. Refer to the wiring diagram
(Figs. 7 and 8) to see how to connect the jumpers
for 120 VAC or 208-240 VAC
For the models supplied with a metal case, connect the
ground wire to the grounding lug on the bottom of the
case.

PROGRAMMING
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
Fig. 12
To change time-of-day and setpoint temperature (First
Level) follow these steps:
Step 1
SET
Press and hold SET for 5 seconds.
The display will show CLoC
Step 2
SET
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
SET
Press SET to accept the new time
Step 5
Press DOWN to go to the next
parameter – Setpoint Temperature -
SEt (cut out)
Step 6
SET
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
SET
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
SET
and
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
SET
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
