differential temperature setting of the boiler. The burner will not start until the outlet water temperature reaches a temperature equal to
the setting for the boiler, minus the differential EX: The boiler is set to heat at 180°F degrees and the differential is set at 30°F. The
burner will not start until the outlet temperature of the system reaches 149°F degrees (180°
– 30°F = 150°F). To adjust, press either
{S1} (Decrease Value) or {S2} (Increase Value) Ranges 5°F to 30°F.
Press
{S3} again and you will see the Indirect Setting de and an alternative value of 119 (with Vision Systems option). To adjust,
press either {S1} (Decrease Value) or {S2} (Increase Value).
The final adjustment in this mode is the Fahrenheit to Celsius measurement. Press
{S3} again and you will see t and alternating value
of F. To change value, press {S1} or {S2} to choose the correct measurement.
C. STATUS MENU
Installers are also able to check the current status of boiler parameters by pressing {S4} for 3 seconds. Once activated, the display will
show |d1| alternating value of the actual outlet temperature. Actual values are displayed for each function. To view the next value, press
{S4} . Listed below are the values which can be displayed. These values cannot be changed. To exit this menu, press {S3} to resume
normal operation.
Function
Value
d1 — Actual Temperature from outlet sensor
d2 — Actual Temperature from inlet sensor
d3 — If using a standard mechanical control, the control will display |1| for closed |0| for open. If the sensor is connected to the
SuperStor Indirect Fired Water Heater it will measure the actual temperature (Vision option).
d4
— Not used
d5 — Actual Temperature from the outdoor sensor (Vision option).
d6 — Actual Fan speed multiplied by 10 (Example: If fan speed displayed is |410| RPM x 10 = 4100 actual fan speed)
d7 — Actual Ionization current read from Flame Rectification probe
d8 — Actual Status of the Central Heating Circulator Off = |0| , On = |1| . (Vision option.)
d9 — Actual Status of the Indirect Fired Circulator Off = |0| , On = |1| . (Vision option.)
d10 — Actual Status bus communication |co| = connected, |no| = not connected
d11 — Central Heating Set Point
d12 — Power On Hours in units
d13 — Total Central Heat Hours
d14 — Total Indirect/dhw Hours
d15 — Passed Ignition Attempts
D. TEST MODE
This function is intended to simplify the gas valve adjustment if needed. Listed below are the recommended limits on each boiler and
the combustion settings. Automatic modulation does not take place when the controller is in Test mode, only temperature limitation
based on the boiler central heating set point. The user will be allowed to increase or decrease the fan speed by pressing in either
{S1}
or {S2} .
To activate Test mode, press
{S2} and {S3} together for 1 second. Once activated, you will see {Ser} in the display and the fan speed
(shown in a multiple of 10). The measurement of the combustion levels should always be taken at the highest and lowest fan speed.
After 10 minutes, the Test mode stops automatically. To exit Test mode, press
{S1} and {S2} together for 1 second.
