COMMISSIONING
Filling the System
Ensure building occupants are warned to stay clear of
the solar hot water heating system components and pipe
work as hot water or steam may be discharged.
For gas boosted Stratco Solarcore
TM
hot water heating
systems, switch off the electric power supplies to the gas
booster and electronic controller and close the isolating
valve on the gas supply to the gas booster.
For electric boosted Stratco Solarcore
TM
hot water heating
systems, switch off the electric power supplies to the
electric heating elements and electronic controller.
Open the hot water tap at the closest sink or basin. Open
the isolating valve on the cold water supply to the hot
water storage tank. The entire solar hot water heating
system will now fill with cold water and expel air through
the hot water tap.
Close the hot water tap at the sink or basin when water
flows continuously without air bubbles or air bursts. Open
the next closest hot water tap and close when water flows
continuously without air bubbles or air bursts. Continue
opening and closing hot water taps until all pipes have
been purged of air.
Check all connections for leaks and tighten or repair if
necessary. Operate the easing gear on the ECV and P&TR
valves on the hot water storage tank to ensure the valves
are functional.
Circulating Pump & Electronic Controller
Turn on the power supply to the electronic controller
and wait for the controller to complete the initialisation
phase. The circulating pump can then be turned on
manually as follows:
INDOOR CONTROLLER
•
Press the “>/+” button until the display shows AC 1.
•
Press the “SET” button and the word “SET” begins
flashing.
•
Press the “>/+” button until the display shows AC 12.
•
Press the “SET” button again to accept the value and
the word “SET” stops flashing.
•
Press the “>/+” button until the display shows MM 4.
•
Press the “SET” button and the word “SET” begins
flashing.
•
Press the “</-” button until the display shows MM 1.
•
Press the “SET” button again to accept the value and
the word “SET” stops flashing.
•
The LED flashes red/green to show the pump is
running.
•
Press the “</-” button to exit the settings menue,
until “TC” and “TS” are shown in the display.
OUTDOOR CONTROLLER
•
Press and hold the pump button.
The circulating pump should now run continuously. This
can be confirmed by checking the flow meter on the
solar non-return valve assembly. The flow rate must be
adjusted to 1.0LPM by turning the screw and aligning
the bottom fo the float with the 1LPM mark on the flow
meter. If the pump does not operate, check all wiring
and connections to the controller and pump. If the wiring
is correct and the pump still does not operate, turn off
power to the temperature differential controller and
contact your Stratco representative.
When correct pump operation has been confirmed,
return the Indoor Controller to fully automatic mode
using the above procedure and changing the operating
mode “MM” to “4”. Important - do not leave the pump
running in manual mode. Confirm freeze protection and
temperature settings.
IMPORTANT NOTE
The controller is factory programmed to the correct
settings. These settings must not be altered.
Gas Booster
This section applies for gas boosted Stratco Solarcore
TM
hot water heating systems only.
Ensure the isolating valve on the gas supply to the gas
booster is closed. Remove the test point screw on the
gas inlet connection of the gas booster and attach a
pressure gauge.
Turn on the power supply to the gas booster but not the
temperature differential controller. Open the isolating
valve on the gas supply to the gas booster. Ensure the
isolating valve on the cold water supply to the hot water
storage tank is open.
Ensure building occupants are warned to stay clear and
then open all hot water taps.
Operate all other gas appliances at their maximum
gas consumption. The gas pressure gauge should read
between 1.13 and 3.0kPa for Natural Gas and between
2.75 and 3.0kPa for LPG. If the gas pressure is lower,
the gas supply is inadequate and the gas booster will
not achieve full heating performance. It is the installers
responsibility to ensure gas meter, regulator and pipe-
work are funtional, sized correctly and rectified as
necessary.
When correct gas pressure has been confirmed, close
all hot water taps and return all gas appliances to their
original settings.
