1. Press
{S3}
once to access
|C|
, Heater Temperature Set Point. To adjust the temperature of the heater,
simply press in the
{S3}
key for three seconds until you see a flashing (C) then an alternating value of
(180). This number is
the factory set point of 180
o
F.
To change the temperature, push either
{S1}
or
{S2}
on the display. The
{S1}
button decreases and
{S2}
increases the set point temperature. The set point temperature can be set as low as 50
o
F or as high
185
o
F. Changes are directly stored and the display returns to normal mode after one minute.
2. Press
{S3}
a second time. The heater will now display
|Ch|
and an alternating value of 15. This is the
Heater Differential Set Point. This function allows the installer to adjust the activation of the burner based
on the differential temperature setting of the heater. The burner will not start until the outlet water
temperature reaches a temperature equal to the setting for the heater, minus the differential.
EXAMPLE:
The heater is set to heat at 180°F and the differential is set at 15°F. The burner will not start
until the outlet temperature of the system reaches 164°F (180° – 15° = 165°).
To adjust, press either
(S1}
(Decrease Value) or
{S2}
(Increase Value). Ranges 5° F to 30° F.
3.
NOTE:
Only in use if using an indirect storage tank. Press
{S3}
a third time and you will see the Indirect
Temperature Set Point
|de|
and an alternating value of 119. Range 95 – 180. To adjust, press either
{S1}
(Decrease Value) or
{S2}
(Increase Value).
4. Press
{S3}
a fourth time to access
|dh|
, the Indirect Differential Set Point. This function allows the
installer to adjust the activation of the DHW call based on the differential temperature setting for the
indirect tank. The pump will not start until the indirect water temperature reaches a temperature equal to
the setting for the indirect, minus the indirect differential. Range 1 – 18. Default 7.
EXAMPLE:
The indirect is set to heat at 130
o
F and the differential is set to 10
o
F. The DHW pump will not
start until the outlet temperature of the system reaches 119
o
F (130
o
– 10
o
= 120
o
).
5. Press
{S3}
a fifth time to access the final adjustment in this mode –
|t|
, the Temperature Measurement
in Fahrenheit to Celsius. To change value, press either
{S1}
or
{S2}
to change the measurement from F
(Fahrenheit) to C (Celsius).
D. STATUS MENU
Installers are also able to check the current status of the heater 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, simply press the
{S4}
key.
Listed below are the values which can be displayed. These values cannot be changed. To exit this menu,
simply press
{S3}
to resume normal operation.
Function – Value
To toggle between values press
{S1}
to go down and
{S4}
to go up. The first function you will see is:
|d1|
— Actual temperature from top sensor
|d2|
— Actual temperature from bottom sensor
|d3|
— Actual tank temperature if an indirect sensor is used.
|d4|
— Not used
