Auxiliary Heating
The system is supported with a default program which can
be customized to meet your individual needs. You can
create a timer program with up to three time periods to
heat the water to a desired value. During the three preset
time periods, auxiliary heater starts working, when the
water temp. in top part of tank (T3) is below preset
turning-on temp.. When it is not in these three periods,
even the tank temp. is lower than the preset temp., the
auxiliary heater won’t work.
Note: In the system diagram, “RH” stands for the auxiliary
heater device: Electric element, Gas stove, boiler, or other
heating source.
Calorimetry
This function is suitable for all the systems. It calculates
four values on saved heat: the current day, the current
month, the current year and the total saved value. By
measuring the temp. (T6&T7) and flow rate of medium,
transfer them to heat amount through the formula:
Q=CMδt
Take system 1 as example: The temp. sensor T7 andflow
sensor have been installed inside the working station . The
user needs to install the sensor T ( the gray NTC sensor
with screw) in the position located in the left system
diagram.
Heat bypass
This function can lower the system temp. by connecting a
radiator when the tank temps. is too high. The install
position is located in the left system diagram.
Leakage protect
The working station checks the voltage and current on the
system working statue automatically.
“
Load is leakage,shut off power and check it.
”
When there is leakage for loadings, the system stops
working immediately. The words (as the left side) shows
on the System Statue page. Meanwhile, all the output
stops. The user must check it and solve the problem as
soon as possible, to prevent the system overheated.
