continue to supply hot water to the building. Please confirm this is working before proceeding.
Step 5. Open the drain valve on the tank. Open the ball valve where the auto-air vent mounts to allow
air to enter the top of the piping.
Step 6. Disconnect power supply to the controller, which will open the Power Outage Drain Valve and
help to drain the solar collector piping.
Step 7. Once fully drained, the system repairs/maintenance can be completed and then, the fill
process above is repeated to return the system to service.
8.10. Controller Setup and Operation
a) Controller Programming
Step 1. Plug controller into protected outlet or uninterrupted power supply (UPS). The controller will
startup in OFF mode. Pumps and valve will not operate until Operation Mode is changed to Automatic.
Step 2. From the Navigation Menu, select the Service Menu. Program the controller date and time
function.
Step 3. Program the remaining controller functions to accommodate your system design. Sample
system designs with suggested controller setting are presented in the separate document
“Apricus_Nth_American_Systems_Schematics”.
Step 4. If more advanced systems or control functions are needed, refer to the controller manual
include with the pump station.
Step 5. Controller can also be programmed by using the included SD memory card.
i) Initialize the SD Card by first inserting it into the controller. Turn the SD Card function ON,
then OFF in the Operation h Menu.
ii) Press the SD Card in to release it from the controller. Insert the SD Card into the USB
adapter and connect to your computer USB port.
iii) Open ReadMe file before proceeding to DataViewer software.
iv) If Windows NetFramework 2.0 is not installed on your computer, you will need to install it
before using DataViewer. NetFramework 2.0 software is located in the WE folder on the SD
Card.
v) Open DataViewer. Follow the on screen instructions. Data fields will not populate until the
SD Card has been inserted into the controller long enough to record data.
vi) Reinsert the SD Card into the controller. Turn the SD Card function ON in the “Operation h”
Menu, then select YES to update setting from the SD Card.
vii) Leave the SD Card in the controller to gather up to one year of system operation data.
1. The controller will start in OFF mode. Pumps and valve will not operate until Operation
Mode is changed to Automatic.
2. Do not remove the SD Card from the controller without first turning the SD Card function
OFF.
b) Basic Controller Settings: Depending on the system configuration the controller settings may be
adjusted. The following table provides the recommended values for the most basic functions that will be
used in a direct flow system. A complete list of all controller functions is presented in section 6.6 and
sample system designs with suggested controller setting are presented in the separate document
“Apricus_Nth_American_Systems_Schematics”.
