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 the
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.
●
Temperature setting
Press “Temperature Adjustment” key once, the set
water outlet 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.
●
Set temperature and actual temperature
“Set Temperature” is the target water outlet
temperature of water module. Due to error of
wate routlet temperature sensor, the measured
temperature may have a deviation from the
actual temperature.
● Contact keys
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.
● LCD indications disappear
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.
● External mounting of wire remote controller
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.
● For simultaneous running of air conditioner heating
and floor heating, or air conditioner heating and
domestic hot water tank heating, the air conditioner
heating and water module heating have balanced
performance(default setting). The air conditioner
heating can take precedence in system by option
setting on the outdoor unit (refering to technical
catalog for outdooor unit).
● During simultaneous running, if the heating capacity
by domestic hot water tank or floor heating is
insufficient, the electric heating of water tank or
water module will be automatically started to
generate additional heat (when the electric heating
setting is active in the in-situ settings), but this may
cause increase of energy consumption, and all
indoor units of air conditioner may be shut down to
reduce energy consumption.
2.6 Precautions for Test Run
● During cooling test run, the unit will not proceed to
heat recovery running.
● If the hot water heating by water module is started
when indoor unit of air conditioner is heating test
run, it will turn to simultaneous heating by indoor
unit and water module, so do not start water module
for heating hot water during heating test run.
2.7 Other Precautions
● If machine is stopped for a long period of time in
winter, drain out water in water module and water
pipes to prevent freezing.
●
If outdoor unit fails, wire controller is used to set
emergent mode (5.1.7 In-situ Settings “G4”). At the
floor heating mode, the electric heating only by
water module can provide heat; at the domestic hot
water mode, the electric heating by water tank may
heat the water.
● Keep the water module power on and water system
unblocked to prevent water freezing, otherwise
an alarm may occur.
