Heating compensation curve setting
The control temperature for heating mode has two methods: fixed and changeable
temperature. The fixed temperature is a fixed value and directly set by the user from
the set area. The changeable temperature is determined by values of ST05, ST06 and
the actual outdoor temperature measured by the OT sensor probe.
This function is selected by SF04:
when SF04:ENABLE COMPENSATION=NO, it is fixed temperature;
when SF04:ENABLE COMPENSATION=YES, it is changeable temperature.
When SF04:ENABLE COMPENSATION=NO, the set temperature at heating is
ST02;
When SF04:ENABLE COMPENSATION=YES, the set temperature at heating will
be controlled by ambient temperature (OT), ST05 and ST06 according to the
following formula:
Set temperature at heating =ST05+ST06 *(ST05-OT).
 ST05 is indoor temperature that the user feel comfortable
 ST06 is the heating compensation coefficient curve factor you select for the heat
pump to work with. Increasing ST06 will increase compensation temperature and
RT will increase relatively.
 OT is the outside temperature.
The calculated temperature can be used for the control reference, but the maximum
data will not exceed ST14
For example:
Set the heating compensation coefficient ST06 =0.7, ST05=20
When outdoor temperature is 0
℃
, the control temperature is
ST05+ST06*(ST05-OT)=20+0.7*(20-0)=34 ℃ ;
When outdoor temperature is -10
℃
, the control temperature is
ST05+ST06*(ST05-OT)=20+0.7*(20-(-10))=41
℃
;
When outdoor temperature is –20 ℃ , the control temperature is
ST05+ST06*(ST05-OT)=20+0.7*(20-(-20))=48
℃
;
User does not need to calculate it .Just check from below curves.
There are three curves with ST05 from 18 to 22 and ST06 from 0.3 to 2.
Calculated result as above can not check from curve below.
