PART 13 – START-UP PROCEDURES WITH VISION 1 OPTION
The Vision I option allows the user to have one temperature for central heating and another temperature for the SuperStor Ultra Indirect
Fired Water Heater. This enables the user to increase the temperature supplied to the indirect water heater by prioritizing flow at a
higher temperature than may be needed for the central heating circuits (this will require two separate circulators). Once the indirect
water heater is satisfied, the Vision I system will switch back to the central heating circuit to continue to heat the living space at a
temperature based on outside temperature. This gives you a higher comfort level and further increases boiler efficiency.
A. PROGRAMMING THE VISION I OPTION
The Vision I option allows the installer to set the system limits and heat curve for the boiler. These system limits should not be changed
by the user. For future reference, it is important to document your settings within this manual after you program the system parameters.
B. VISION 1 PROGRAM ACCESS
Press and hold {S3} and {S4} simultaneously for three seconds to begin. You will notice that the display will change to |000|. Then,
press down {S1} until you see |925| on the display. This is the pass code. Press and hold {S3} for 1 second to confirm the pass code. If
the pass code is entered incorrectly, the controller program function will be cancelled and the control returns to normal operation. If the
code is entered correctly, the control will switch off the gas valve and purge fan while showing a solid |---| in the display. The display will
then show a |1| alternating to |de|. This first function verifies that the control will address the requirements of the indirect water heater.
C. VISION 1 PROGRAM NAVIGATION
Next you will have to press {S3} to move through each function. To increase or decrease a value, you will need to press either {S1} or
{S2} to change the default values. If there is no key action for 1 minute, the display returns to normal operation. Changes are effective
immediately but not directly stored until the {S4} key is pressed down for 3 seconds then the new values are stored. Listed below are
the varieties of functions the installer can program into the Vision I System.
NOTE: The boiler cannot be programmed when there is a call for heat. See Table 14 to set outdoor reset curve.
