Operation manual
8.4.16 General error
The parametrised input for the general error is continuously monitored and
"A15" appears in the display if the input is activated to indicate that there is a
general error. In addition, the fan is switched off and the heating and cooling
valve closed.
8.5 Outputs
"Output 1" and "Output 2" functions can be assigned in the respective sub-
menus in the "Outputs" menu. The polarity of the outputs can be individually
changed. The outputs are assigned with the following functions:
•
Heating valve
•
Cooling valve
•
Collective fault (set as soon as one of the error messages A11 – A18 is
enabled)
•
Condensation/dewpoint
•
Motor fault
•
Frost protection fault
•
Unit frost protection fault
The following parameters can be set in addition to the functions of the outputs:
Max. heating load:
Max. cooling load:
Valve protection:
Manual mode:
This parameter is used to optimise compensation of inherent heating
when there is a switched load. The maximum possible load produced
by the heating valve and fan speed must be taken into account when
selecting the value.
see maximum heating load
The Climate Controller features a valve protection function to ensure
that the valves remain functional even when not used for an extended
period of time. Valve protection is only started if the corresponding
valve has not been activated for more than 96 hours.
Valve protection for the heating valve is fixed at Fridays 11:00, and
11:15 for the cooling valve. The valves are each actuated for 5
minutes.
This feature can be disabled.
The digital outputs and the analogue output can be manually actuated
to check that they are working correctly in the Manual mode menu. If
an output is set to manual mode, it is indicated by an icon () in the
header of the Home screen.
