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. Setpoint, frost protection function.
Only when water heating with frost protection has been configured.See also
pages 27 and 29.
Factory setting 7°C.
Range 0...60°C.
2. Setpoint shutdown control.
Only when water heating with frost protection has been configured.See also
pages 27 and 29.
Factory setting 25°C.
Range 0...60°C.
3. Pump stop.
Only when water heating has been configured. Outside temperature above
which the pump is permitted to stop with no heating requirement, i.e. output heat
is less than 1%. Delay time for the pump can also be set.
Factory setting 6°C. and 15 minutes.
Range 0...20°C. and 0...60 min.
4. Supply air fan run on time for cooling electric heater.
Only if electric heating has been configured.
Factory setting 120 sec.
Range 0...180 sec.
5. Supply air fan delay at normal start up. Period for which heat exchanger is to run
at 100% at start up.
Startup is normally done with only the exhaust-air fan running. With C20 and
C40 the fan will be running at reduced flow. With C10 and C30 the fan will be
running at low speed it two-speed running has been configured, otherwise at
normal speed. After the set time the supply-air fan is started at reduced flow
level(C20 and C40)/ low speed (C10 and C30) if two-speed running has been
configured. If the fans shall run at normal speed the exhaust-air fan will now
switch to normal speed and 5 seconds later also the supply-air fan.
If any of the temperature control outputs has been configured as heat
exchanger, this output will at startup be set to 100%, that is to maximum heat
exchange, for the set time. The other outputs will be held at 0 % output until the
supply-air fan is started. If a cooling demand is at hand, the cooling output will
not be activated until the exchanger startup period has run out.
Factory setting 60 sec. and 90 sec.
Range 0...180 sec. and 0...600 sec.
6. Extended running. When set for DI7/DI8 using pushbutton. See page 30.
Sets required running time after using push button. The function is not additive
i.e. multiple pressings of the button will not give longer running time.
Factory setting 0 min.
Range 0...180 min.
7. P-band Y2,Y3. Factor of P-band for Y1.
Multiplication factor compared to the proportional band set for output Y1.
Does not normally need setting. Option available for plants where control
enhancement for respective devices are different.
Factory setting 0.5 / 0.5.
Range 0...10 and 0...10
8. Minimum fresh air percentage when using mixing dampers on Y1 or Y2.
See page 30.
Factory setting 0%.
Range 0...100%.
9. Free cooling. Lowest outdoor temperature and differential between room and
outside temperature. See page 30.
Factory setting 10°C. and 3K.
Range 0...30°C and 0...10K.
10.Free cooling. Setpoint for room temperature. See page 30.
Factory setting 21°C. Range 0...30°C.
11.Cooling recovery. Differential outdoor temperature/room temperature.
See page 30.
Factory setting 2K.
Range 0...60K.
