Move right to a lower menu level

(Move the curser to the right in the para-

meter)

LEFT:

Move left to a higher menu level.

(Move

the curser to the left in the parameter)

OK/ENTER: Open/activate a selected

menu/setting

(Conrm a parameter value)

ALARM: Press for alarm list

CLEAR: Abort a parameter setting and

restore the original value, if ”OK/EN-

TER”not yet has been pressed.

ALARM LED: Red light is ashing for

unacknowledged alarm. Permanent red

light for acknowledged alarm, but the

alarm is still active, because the reason is

not yet eliminated.

"WRITE ENABLE" LED: Yellow light – slow

ashing indicates that a parameter can be

selected for changes, when the OK/EN-

TER button is pressed.Yellow light – fast

ashing indicates that the parameter is

activated for changes. Permanent yellow

light indicates that the changes are going

on.

for the alarm has been solved. The Class A

alarm can be triggered by the temperature

sensor inside the water heating coil if the

temperature falls below the set point value,

or the class A alarm can be triggered by the

re thermostats when the temperature rises

above the set point values, indicating risk of
