Connection Of An External Ac-Reheating; Operation - fothermo PVB-30-AC Bedienungsanleitung

CONNECTION OF AN EXTERNAL
AC REHEATING:
IMPORTANT! Only use certified connection plugs
(IEC-320 - C13 plugs) recommended by the manufac-
turer. Non-compliance will invalidate the warranty
and may damage the water heater.
The external reheating feature extended use of the
photovoltaic boilers. For example, long periods of
bad weather can be bridged by connected AC power.

OPERATION

to the water heater.
Operation
Switch On:
Press the - b utton for three seconds.
Display:
The present water temperature is shown on the
display.
• POWER IN: Input power of the PV modules
• VOLTAGE: Input voltage of the PV modules
• USED PV ENERGY: Total PV energy utilised
Menu Navigation:
Press the - button briefly. By pressing the
button again, you jump to the next page in the
menu.
Settings:
Press the - button repeatedly. This allows
individual adjustments on the unit to be made.
Please note: The adjustments are only active
when an external energy supply is connected to
the photovoltaic water heater.
• CHANGE SYSTEM MODE:

Quick guide: System modes
Mode 1 (photovoltaic)
For the direct connection of photovoltaic modules.
If desired plus a fothermo AC-reheating via mains
current.
Mode 2 to 3
For the connection of other energy sources such
as a battery. A battery cable is needed to plug in
the battery via MC4-connectors. The battery is not
included. More detailed information can be found
in the respective product description.
Switch off:
Press the - button for three seconds.
Set reheating temperature
If external mains voltage is connected. The garanted
teperature which the water heater holds all time can
be adjusted with the rotary knob.
In summertime when the sun is shining proberly and
the water heater is able to ensure reliable heating
with PV alone, the recommendation is to set the
rotary knob to the lowest temperature.
If the solar radiaton is not enough, set the rotary
know to the requested temperature (recommen-
dation 35°C to 40°C).
Further important notes:
Leakage of water
The pressure relief valve can drip during the opera-
tion of the water heater due to the expansion of the
water while heating. Ensure that the leaking water
is directed to a collection container or a drain. The
dripping of water does not indicate a defect. The
side valve opening must not be closed under any
circumstances.
The installation of a drainpipe facilitates future main-
tenance and servicing operations, as the water can
be drained from the water heater easily.
Noise emission
Noise may be generated inside the device during
the heating process, which is caused by lime
deposits on the heating element. An increased
formation of limescale can be observed at water
temperatures above 60°C. This may cause impair-
