3. Wire Remote Controller (See Fig.3.1.)
The wire remote controller comprises two major
parts. The upper part is LCD screen and the lower
part includes functional keys.
Fig.3.1 indicates the LCD displays and operation
keys of water module.
Press keys only by finger and use of other objects
may damage the keys. Do not touch “CHECK” key
because it is only intended for technical service
personnel. If press this key by accident, press
again to recover.
For convenience of understanding, Fig.3.1
shows anything that can be displayed. In normal
running, only part of icons will display on th
LCD screen.
Although the LCD display includes the icons of
swimming pool water, fan coil, boiler and solar
energy etc., this water module does not have
these functions.
Ɣ 7HPSHUDWXUHVHWWLQJ
Press “Temperature Adjustment” key once, the set
outlet water temperature will increase or decrease
1°C. During floor heating, the lowest set
temperature is 20°C and the highest set
temperature is 55°C; during domestic hot water
running, the lowest set temperature is 35°C and
the highest set temperature is 75°C.
Ɣ 6HWWHPSHUDWXUHDQGDFWXDOWHPSHUDWXUH
“Set Temperature” is the target outlet water
temperature of water module. Due to error of
outlet water temperature sensor, the measured
temperature may have a deviation from the
actual temperature.
Ɣ &RQWDFWNH\V
The keys on the remote controller are contact type
which only needs being pressed by finger. The
running status may be confirmed on the LCD
screen.
Ɣ /&'LQGLFDWLRQVGLVDSSHDU
If all indications disappear during system running,
this is because of communication signal distortion
by electromagnetic interference. In this case, cut
of the power and energize again, the
communication failure may be eliminated.
Ɣ ([WHUQDOPRXQWLQJRIZLUHUHPRWHFRQWUROOHU
If water module is installed at a position
inconvenient for operation, remove the wire
remote controller, power off and then use the
shielded twisted pair to lead out and mount. The
wiring path should not cause short circuit or circuit
break of communication lines. The longest
leading-out line is 500 meters long.
