ation was measured. Next, enter this deviation for RT1. If the
offset was determined only for one temperature, it is neces-
sary to enter for T2 and RT2 the identical values as for T1
and RT1. RT1(2) is then added to the display.
If the deviation of the set temperature was determined for a
value different to T1, this can be defined as RT2 for T2. Then,
in addition to an additive offset, the increase of the character-
istic is also changed. The value correction on the display
takes place automatically for the entire range of values. If an
offset is shown between the analog output actual tempera-
ture and the actual temperature shown in the display, the dif-
ference between the two values can be entered as the
correction value with the function ”RAT output”. The entered
value is added via the interface to the analog box output ac-
tual value.
These two RTA values are effective only for the connected
analog box.
24.6 Reaction in the event of alarm
Following activation of the analog interface, the new function
”E--action” appears in the display. Pressing the function key
several times enables you to select how the thermostat
should behave when the analog box shows a malfunction or
if the connection is interrupted.
If ”ALARM” is selected, the thermostat goes into the alarm
state, i.e. the pump and heating are switched off.
In the case of ”Last value”, the thermostat continues to run
with the last set value defined via the analog interface.
With ”S4”, the set value S4 is used as the new set tempera-
ture in the event of an alarm.
24.7 Stopping the input via the I/O plug
In order to end the entry via the analog connection, you deac-
tivate the analog interface in the „Settings“ / „Interfaces“
menu.
