3. Commissioning of station
Attention: Risk of scalding!
In order to prevent the boiling of solar fluid in the collectors, the system should not be
flushed or filled during periods of strong sunshine.
Attention: Risk of frost!
Solar thermal system cannot be completely emptied after flushing. There is a danger of
frost damage if water is used for flushing. Only use solar fluid to flush and fill the solar
thermal system. Use water –propylene glycol mixture as solar fluid (Maximum 50%
propylene glycol).
3.1 Flushing and filling the solar system
Flushing and filling unit is the optional
component, it can be installed horizontally
at the lowest point of the solar circuit (see
figure). A filter must be installed between
the store and solar pump in order to
prevent the flushed-out scale from store
re-entering the solar circuit.
Flushing and filling steps:
Disconnect the expansion vessel from
the solar thermal system.
Connect the pressure hose of a flushing and filling station to the fill ball valve (1) of
flushing and filling unit.
Connect the flushing hose of a flushing and filling station to the drain ball valve (3) of

will use the signal of sensor T2 automatically to control the auxiliary heating or the
circulation pump.
1 collector array –1 storage tank –1 pump and auxiliary heating
Description:
The solar circuit pump (P1) is switched on as soon as the switch-on temperature difference
(△Ton) between the collector array (T1) and the storage tank (T2) is reached. If the
temperature difference between the collector array (T1) and storage tank (T2) drops below
the switch-off temperature difference (△Toff), or the temperature of storage tank (T3)
reaches the preset maximum storage temperature, then the solar circuit pump (P1) is
switched off.
Back-up heating by auxiliary boiler (detailed see paragraph 3.2):
Within the preset schedule of back-up heating, if the temperature T3 is below the preset
switch-on temperature, then the back-up heating（H1）is triggered, when T3 is heated to
the preset switch-off temperature, back-up heating H1 is ceased.

3.2 tHET Timing heating
Description:
Electrical heater, gas boiler or oil boiler can be integrated into solar system used as back-up
of system, and they can be triggered automatically at preset schedule by preset
temperature. Within a preset schedule, when the temperature (T3) of top part of tank
drops below the preset switching-on temperature of this function, back-up heating starts to
work, when T3 rises up to the preset turning off temperature, back-up heating is stopped.
Within 24 hours, three time sections can be set with this controller.
Factory set:
The first schedule: back-up heating function starts at 4:00 and ends at 5:00 am. Within
this time section, switch-on temperature is 40oC; switch-off temperature is 45oC.

The second schedule: from 10:00 to 10:00 am, it means there is no back-up heating in this
time.
The third schedule: back-up heating function starts at 17:00 and ends at 22:00 pm.
Within this time section, the switch-on temperature is 50oC; switch-off temperature is 55oC.
The switch-on temperature adjustable range: 10 oC ~ (OFF-2oC)
The switch-off temperature adjustable range: (ON+2 oC) ~ 80oC
If you want to shut off one timing heating, then you can set the turning on time and turning
off time with a same value ( for example, no this function during the second time section,
then you can set turning on/off time is 10:00 ~ 10:00)
When time is outside of the preset schedule, back-up heating doesn’t work automatically
even when the tank temperature reaches the switch –on temperature of heating.
Note:
When there is no sensor installed in the top part of tank (no T3 sensor), controller will
take the signal of T2 (sensor in bottom of tank) automatically to control this function.
The time in this controlled is 24 hours mode, when you set schedule, the switch-off
time of heating should be larger than the switch-on time. For example: if you set the
switch-on time of heating is at 17:00, but switch-off time of heating is 6:00, then this
setting doesn’t take effect, that means within this time section, heating function doesn’t
work. The correct set is like flowing: it should be divided into two time sections, one
time section is from 17:00 to 23:59, the other time section is from 00:00 to 06:00.
Setup steps: under standby status.
