13.1.5 Target Water Temperature at Extension System (Optional PCB is connected)
Target water temperature is calculated as below.
Heat Mode:
o
When buffer tank selection is “YES:”
Target water temperature = Target buffer tank tempe [2°C]
o
When buffer tank selection is “NO”
If both zone 1 and zone 2 is active
Target Water Temperature = Higher zone target water temperature of Zone 1 and Zone 2.
If only one zone is active
Target Water Temperature = Zone target water temperature of active zone.
Cool mode:
o
When buffer tank selection is “YES”
If both zone 1 and zone 2 is active
Target Water Temperature = Lower Zone Target Water Temperature of Zone 1 and Zone 2 + [-3°C]
If only one zone is active
Target Water Temperature = Zone Target Water Temperature of active zone + [-3°C]
o
When buffer tank selection is “NO”
If both zone 1 and zone 2 active
Target Water Temperature = Lower Zone Target Water Temperature of Zone 1 and Zone 2
o If only one zone is active
Target Water Temperature = Zone Target Water Temperature of active zone
13.1.6 Target Zone Water Temperature Control
Purpose:- To control zone mixing and zone pump according to the zone sensor temperature
13.1.6.1 Target Zone 1 water temperature setting control
Start condition
o
Heating zone 1 is ON by remote control or Timer or Auto Mode
OR
o
Cooling zone 1 is ON by remote control or Timer or Auto Mode.
Cancel condition
o
Heating zone 1 is OFF by remote control or Timer or Auto mode
AND
o
Cooling zone 1 is OFF by remote control or Timer or Auto mode.
Target Zone 1 water temperature is calculated as below condition.
o
Target Zone 1 water temperature = A (Base temperature) + B (shift temperature)
A (Base Temperature)
Compensation
Direct
Value from the curve + User shift value set
Direct value from user setting
* During heat mode and compensation select, if powerful mode is activated, higher value of WLo or WHi will be use
as curve value.
