Rot. Exch
The heat exchanger unit can be set to one of the following alternatives:
•
Plate exchanger
•
Rotating exchanger
•
Liquid connected exchanger
•
Mixing dampers
•
Not connected
•
Damper limiting for minimum outdoor air percentage is settable 0…100%.
In the submenu parameters for outdoor temperature control of exchanger can be set.
Outd. temp control of
exch: Off
Outd. temp start: 10°C
Diff. stop: 0.2°C
For detailed description of exchanger alternatives, see section 5.1.3 Heat exchanger.
16.9 Chiller
Cooling
Water
Select chiller type: "Water", "DX", "DX with exchanger control" or "Not used".
For detailed description of DX-cooling, se section 5.1.4 Step controllers.
If DX cooling has been configured, there are submenus for setting of certain operation parameters.
Min limit lowering
If DX cooling is used in combination with room or extract air control, the supply air temperature
minimum limit value can be lowered to give smoother (more continuous) running of the chillers.
The set lowering of the limit value is activated when the DX cooling is running.
Lowering of min
limit for supply air
control on active
DX cooling: 5.0°C
This parameter is also used for setting the lowering of the cooling setpoint when running "DX
cooling with exchanger control".
