3.2.30 Improved Comfort in Cooling by Te Control
You can increase the comfort feeling for the customer by limiting the lower Te value.
With higher Te values, the latent capacity will drop (and eventually the sensible capacity).
The EER should increase => Similar as high sensible mode in VRV
Current setting Te lower limit:
Currently it is possible to modify the lower limit of the Te value with field setting (especially used
for EDP application).
TeS Lower Limit Value
However these values are not high enough for high sensible mode.
New higher setting Te lower limit:
Change field setting 33 (in Mode 2) with following values for "TeS Lower Limit value".
TeS Lower Limit Value
The highest value has priority (if 2-33- is activated => most likely these values). However
protection control of unit has highest priority.
The highest value between setting 11 and 33 will overrule.
Do not change the value of setting 33 when EDP setting is set.
For WHC: See "Weather Depending Control".
3.2.31 Improved COP in Heating by Tc Control
The COP could be increased (with reduction of capacity) by lowering the "TcS Upper Limit
values".
Upper limit Tc control:
Change field setting 34 to change the (TcS Upper Limit value). Now this value is controlled by
Pe and no field settings.
TcS Upper Limit Value
The normal protection control has a higher priority than the new TcS upper limits.
For WHH: See "Weather Depending Control".
3.2.32 Weather Depending Control
When the TeS and TcS values are changed depending on the ambient outdoor temperature the
COP and EER can be increased.
In cooling mode: If ambient temperatures are low, the requirement for quick cooling is small.
This way the EER can be improved by increasing the "TeS Lower limit values".
In heating mode: If ambient temperatures are high, the requirement for quick heating is small.
This way the COP can be improved by decreasing the "TcS Upper Limit values".
