This device complies with Part 15 of the FCC Rules and it
contains licence exempt transmitter(s) / receiver(s) that
comply with Innovation, Science and Economic
Development Canada's licence-exempt RSS(s).
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference;
(2) This device must acceptany interference, including
interference that may cause undesired operation of the
device.
Only operate the device in accordance with the instructions
supplied.
Changes or modifications to this unit not expressly
approved by the party responsible for compliance could
void the user's authority to operate the equipment.
This device complies with FCC radiation exposure limits
set forth for an uncontrolled environment. In order to avoid
the possibility of exceeding the FCC radio frequency
exposure limits, human proximity to the antenna shall not
be less than 20cm (8 inches) during normal operation.

Le présent appareil est conforme aux CNR Innovation,
Sciences et Développement économique Canada
applicables aux appareils radio exempts de licence.
L'exploitation est autorisée aux deux conditions suivantes:
(1) il ne doit pas produire de brouillage et (2) l' utilisateur du
dispositif doit étre prêt à accepter tout brouillage
radioélectrique reçu, même si ce brouillage est susceptible
de compromettre le fomctionnement du dispositif.
Cet émetteur ne doit pas être Co-placé ou ne fonctionnant
en même temps qu'aucune autre antenne ou émetteur.
Cet équipement devrait être installé et actionné avec une
distance minimum de 20 millimètres entre le radiateur
et votre corps.
NOTE
This equipment has been tested and found
to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide
reasonable protection against harmful
interference in a residential installation. This
equipment generates, uses and can radiate
radio frequency energy and, if not installed
and used in accordance with the instructions,
may cause harmful interference to radio
communications. However, there is no
guarantee that interference will not occur
in a particular installation. If this equipment
does cause harmful interference to radio or
television reception, which can be
determined by turning the equipment off and
on, the user is encouraged to try to correct
the interference by one or more of the
following measures:
· Reorient or relocate the receiving antenna.
· Connect the equipment into an outlet on
a circuit different from that to which the
receiver is connected.
· Consult the dealer or an experienced radio/
TV technician for help.
5.6 Auto-restart
If electricity power failed, unit can memorize all setting parameters,
unit will be back to the previous setting when power recover.
5.7 Button Auto Lock
When there is no operation of button for 1 minute, button will be
locked except Unlock button
5.8 Screen Auto Lock
If there is no operation of button for 60s, screen will be locked
(extinguished) except for error code and alarm icon.Press any
button will unlock the screen(lighten). Enter engineering mode 35
channel enable this function.
6. TROUBLE SHOOTING
6.1 Non-error tips
Q: Why compressor can't start immediately after setting?
A: Unit will wait for 3 minutes to balance the pressure of system
before starting compressor again, it's a self protection logic of unit.
Q: Why sometimes the temperature shown on the display panel
decreased while unit is running?
A: When the upper tank temperature is much higher than the bottom
part, upper part hot water will be mixed by the bottom cold water
which is continually flow from inlet tap water so that will decrease
the upper part temperature.
Q:Why sometimes the temperature shown on the display decreased
but unit still keep closed?
A: To avoid unit ON/OFF frequently, unit will activate heat source
only when bottom tank temperature is lower than setting
temperature or max. temperature for at least 6 ºC.
Q:Why sometimes the temperature shown on the display will
decreased dramatically?
A: Because tank is pressure-bearable type, if there is massive hot
demand, hot water will quickly tapped out from upper part of tank
as well as cold water will quickly tapped into bottom part of bank
if the cold water surface emerge the upper temperature sensor,
temperature shown on the display will decreased dramatically.
Q: Why sometimes the temperature shown on the display is
decreased a lot, but there is still a mount of hot water can be
tapped?
A: Because the upper water sensor is located on the upper 1/4 tank,
when display temperature starts falling down quickly, it means
there is at least 1/4 tank of hot water available.
