you set the heater’s power at appropriate value (always
consider the capacity of your home’s electrical system).
Notice: Conguration must be performed before initial
start-up when power supply is switched off. Set 2 (two)
switches at proper position to congure a heater. The
switches are located on electronic board. Each switch has
4 (four) positions, they are described as
P
(power settings)
and
F
(other settings). Switch on a power supply to upgrade
conguration. After you supply power to PPE2 or PPVE
a display will show: (PW...) - software version of control
panel, (MSP...) - software version of controller and the
value of rated power that has been set for the heater
(PPE2; PPVE).
P
switches settings (for PPE2, KDE2, PPVE):
• 1, 2 - rated power of heater,
• 3, 4 - type of heating box,
Do not reset P switches for KDE - keep factory
settings intact.
