4. Usage
2.Heating / Cooling circuit 2
2.01
Set whether the system has the second circuit .
2.02 Set Temp For Cooling
Set the set temperature for cooling operation of circuit 2.
2.03 Set Temp For Heating
If heating curve function is disabled for circuit 2, a fixed value of set water temperature in heating
mode can be set here.
2.04 With/Without Mixing Valve 2
Set whether circuit2 has a mixing valve connected. For more details, please refers to chapter 2.1.5
2.05 Heating Curve
Turns ON/OFF of heating curve function for circuit 2.
2.06 Water Temp. A/Ambient Temp. 1
2.07 Water Temp. B/Ambient Temp. 2
2.08 Water Temp. C/Ambient Temp. 3
2.09 Water Temp. D/Ambient Temp. 4
2.10 Water Temp. E/Ambient Temp. 5
Temperature set here is water temperature, it is based on the same ambient temperature settings for
circuit 1, parameters 1.06~1.10.
Temperature settings of the heating operation for circuit 2 VS ambient temperatures. Controller will
create a heating curve for secondary heating system according to these settings. If parameter 2.05 is
OFF, only 2.03 needs setting, and unit will take this set value as fixed set water temperature for
secondary heating system.
2.11 High Temperature Limit
2.12 Low Temperature Limit
These two parameters are used by the installer, to set the set temperature range for circuit 2 for safety
purpose.
