14.1.3 Target Water Temperature Setting
14.1.3.1 Target Water Temperature Control of Standard System (Optional PCB not
connected)
There are 2 types of temperature control selection which are Compensation and Direct.
Temperature control type selection by installer:
1. Compensation : Wlo, WHi, ODLo, ODHi can be set at installer menu.
2. Direct
: Direct Water Temperature Set
Remote control setting by user:
1. Compensation
: Shift value ±5°C from the compensation curve
2. Direct
: Direct water temperature set change
*This setting only able to set when room sensor select as Water Temperature.
*Instead of water temperature, user will set target room temperature when room sensor select as Room Thermistor
OR Internal Room Thermostat.
Target water temperature is calculated as below condition.
o
Target 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
o
B (shift temperature) value is depend on the room sensor selection at remote controller as below table:
B (Shift Temp.)
B shift value depend on the room sensor selection at remocon as table below
Sensor selection
Water temperature
B = 0
External Room thermostat
B = 0
Internal Room thermostat &
Room Thermistor
Heat Mode:
B = 0 ; when Zone OFF or Zone Room Thermo OFF
B = follow Heating Room Temperature PI control logic
Maximum/minimum regulation of Target Water Temperature
Heating
Max
55°C
Min
20°C
Compensation Type: (Operation under Heat Mode)
The set temperature defines the parameters for the ambient (Outdoor temperature) dependent operation of the
unit. The water temperature is determined automatically depending on the outdoor temperature. Default setting is
the colder outdoor temperature will result in warmer water and vice versa. The user has the possibility to shift up
and shift down the target water by remote control setting.
