T1 to T3 Displays the value measured at the sensor (S1 - T1, S2 - T2, S3 – T3).
E1 to E6 Displays the values from external sensors which are read via the DL-bus. Only
activated inputs are displayed.
ERR means that no valid value has been read. In this case the external value is
set to 0.
SPS Speed stage (only ESR31-D), indicates the current speed stage. This menu
item is only displayed if the speed control is activated.
Display range: 0 = output is off
30 = speed control is running at the highest stage
ANL Analogue level indicates the current analogue level of the 0-10V output - only
displayed if the 0-10V output control system has been activated.
Display range: 0 = output voltage = 0V or 0% (PWM)
100 = output voltage = 10V or 100% (PWM)
l/h The volume flow, indicates the flow rate of the volume flow encoder (only possi-
ble to input 3), or the volume flow rate of an external sensor via DL, or the fixed
volume flow in litres per hour.
kW The current output of the heat counter indicated in kW.
MWh Megawatt hours, indicates the megawatt hours of the heat counter.
kWh Kilowatt-hours, indicates the kilowatt-hours of the heat counter.
When 1000 kWh have been reached the counter restarts at 0 and the MWh are
increased by 1.
Menu items l/h, kW, MWh, and kWh are only displayed if the heat counter has been activat-
ed.
Status: Display of the system’s status. Depending on the program selected, various
system statuses are monitored. If any problems have occurred, this menu con-
tains all of the information.
PAR: The navigation keys on the parameter level (, ) allow you to select the icons
under the temperature display and the text line. The parameter selected can
now be released for selection with the down key (enter). The parameter
blinks to indicate release. Press one of the navigation keys to change the value
by one increment. Keep the key pressed to keep the value running. The
changed value is adopted when the UP key (return) is pressed. To prevent
unintended changes in parameters, entry in PAR is only possible using the
code 32.
MEN: The menu contains basic settings to determine additional functions such as the
sensor type, language, the system protection functions, etc. Use the keys for
navigation and to make changes as usual. The dialogue is only set up via the
text line. As the settings in the menu change the basic features of the control
unit, entry is only possible with a code that only the technician knows.
The settings of the parameters and menu functions ex works can be restored at any
time using the down key (entry) when plugging the unit in. If this occurs, WELOAD will
appear in the display for three seconds.
Warning! All parameters and menu points already set will be deleted.
