Main page.
It displays the battery voltage (V
BAT
), the charge program currently selected (either
SEAL or FLOOD), the night/day status detected by the PV module. The load icon, if ON,
indicates that the load is power supplied.
button
It displays the current (I
PAN
) of the PV module. We remember that the current
delivered by the PV module depends on its state of sun-lighting and on battery charge
status. With charged battery (Vbatt>14,4V @12V or Vbatt>28,8V @24V) and even
with a good lighting of the PV module, you have low charge currents since the
regulator limits such current so to avoid the battery overcharge.

button
It displays the power in watt actually delivered by the PV module.
button
It displays the counter of energy that is delivered by the PV module in KWh. It is
possible to reset this measure by pressing simultaneously the buttons
for 2
seconds.
button
It displays the charge current inside the battery (I
BAT
).
button
It displays the battery temperature that is currently measured by the temperature
sensor connected to WRM-15.
button
Visualization of parameters of the output load. With Leonardo System 3000, the
output load is managed by the DC/AC inverter. For this reason the values in the WRM-
15 charge controllers remain zero.

System Configuration
On each charge controller code WRM-15 you have to set the correct type of used battery. You go to the
configuration pages of WRM-15 by pressing simultaneously the buttons
for at least 2 seconds.
Charge program configuration page
It sets the charge voltage for battery.
We recommend to set the SEAL program for gel or sealed batteries and the FLOOD
program for the charge of flooded lead acid batteries.

Float voltage
It is possible to modify
the charge voltage of float phase (VFlt at 25°C). When
battery voltage is equal to the end-charge voltage (Vch) for a time equal to T
Absorption (configurable) you enter in float phase. VFlt is compensated in
temperature (-24mV/°C at 12V and -48mV/°C at 24V).
