Settings
This menu contains various settings that are normally only set at the comissioning of
the C
ORRIGO
.
Which alternatives are shown depends on the model and the configuration settings.
1. K-factor HS1-Room
Sets the ratio between a change in supply water temperature and the resulting
change in room temperature. A K-factor of 3, for example, means that a 3K
change in water temperature will give a 1K change in room temperature.
2. Outdoor temperature compensated night reduction HS1
When using outdoor temperature compensated night reduction, full reduction
will be obtained for outdoor temperatures down to +10°C. At lower outdoor
temperatures the reduction is gradually reduced to become zero at -10°C and
lower.
3. K-factor HS2-Room, As for HS1 above.
4. Outdoor temperature compensated night reduction HS2, As for HS1 above.
5. Pump stop HS1. Minimum outdoor temperature and delay time.
Exercising 5 minutes per day.
6. Pump stop HS2. Minimum outdoor temperature and delay time.
Exercising 5 minutes per day.
7. Show Min/Max-temperatures for AI-inputs.
The lowest and highest values encountered since the last activation of the
function are stored and will be displayed for each input under the menu
Analogue in.
LEDs
The LEDs are connected to the functions of certain in- and outputs. Normal running
indication is yellow. A red LED signifies an error. The text strip can easily be changed
to reflect various configurations
Diode Text Function yellow Function red
1 HS1 Pump monitor Pump error
2 HS1-CV Control valve HS1 Control error
3 Exp vess --- Pressure loss
4 THW Control valve THW Control error
5 THW-P Pump monitor Pump error
6 HS2-P Pump monitor Pump error
7 HS2-CV Control valve HS2 Control error
Alarm -- --- Alarm active
For LEDs 2 and 7 the following applies:
If the output is configured for 0...10V the LED will light up when the output goes
above 2%.
If the output is configured for 3-position control LED will be yellow for a signal to
increase the output and orange for a signal to decrease the output.
Storage of programmed parameters
All settings are stored in non-volatile memory so the unit does not need
reprogramming after a long power failiure.
The clock has a power reserve of at least 24 hours.
After longer power failiures the clock will need resetting but not the programmed
scheduler parameters.
The alarm list will be erased in the event of a power failiure.
