Panasonic AQUAREA WH-ADC0912K6E5AN Service Manual page 131

Time from start (minutes)
Coefficient
The operating frequency will gradually increase when the capacity is deemed insufficient by referring to dRange
value:-

dRange = Current water outlet temperature - Water outlet set temperature
dRange value is checked every 10 minutes.

If current dRange < previous dRange, the new coefficient value will increase by 0.1.
Maximum frequency after change is limited by Zone limit maximum Hz.
Stop condition
When any one of below conditions achieved

Remote control setting = Comfort

It is test mode

Compressor run time ≥ 1 hour

Present water outlet temperature - Water outlet set temperature < -10°C

Outdoor ambient < -10°C
14.1.3 Cooling Operation
14.1.3.1 Thermostat Control

Compressor is OFF when Water Outlet Temperature – Internal Water Setting Temperature > -1.5°C for
continuously 3 minutes.

Compressor is ON after waiting for 3 minutes, if the Water Outlet Temperature – Water Inlet Temperature
(temperature at thermostat OFF is triggered) >3°C.
14.1.3.2 Cool Mode Operation
1. ways valve control:
3 ways valve switch and fix to cooling side.
o
2. Heat pump operates follow normal cooling operation.
3. Room heater DOES NOT operate during cool mode.
4. 2 ways valve control:
2 ways valve is closed.

14.1.4 Target Water Temperature Setting
14.1.4.1 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
2 Direct

Remote control setting by user:
1 Compensation
2 Direct
*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.
Target water temperature = A (Base temperature) + B (shift temperature)
o
