function Codes 28 and 29
These two functional codes set control parameters for the DHW
heating operation.
If the Hot Water DHW icon is displayed on the remote controller,
DHW is enabled. It can be activated through manual button input or
scheduled programming (Figure 64).

function Code 2B
This function code sets DHW heating timers.
Determine time duration, operation time and
stop time of the DHW tank heating.
• Value #1 of Function Code 2B: Sets how
long DHW tank heating can be continued.
• Value #2 of Function Code 2B: Set how
long DHW tank is stopped (non-heating
mode). This function is also used to cycle
on and off time spans for the DHW tank
heating cycle.
• Refer to Figure 63 for examples of a timing
sequence chart.

• Value #1 of Function Code 28: Temperature range or setpoint as
input from Value #2 of Function Code 28.
• Value #2 of Function Code 28: Maximum temperature.
— Example: If Value #1 is set a '5' and Value #2 is set as '80',
the water tank heating will be started when the water tank
temperature is below 167°F (75°C).
• Value #1 of Function Code 29: Temperature range or setpoint from
target DHW temperature.
• Value #2 of Function Code 29: Determines heating demand priority
between DHW tank heating and under floor heating.
— Example: If target temperature is set as '50' and Value #1 is
set as '3', then water tank heating will be turned off when the
water temperature is above 127°F (53°C). Water tank heating
will kick on when water temperature is below 122°F (50°C).
— Example: If Value #2 is set as '0', that means heating priority
is on DHW heating. Note that under floor heating can not take
place while DHW heating is priority. If Value #2 is set to '1',
heating priority will then focus to under floor heating and in this
case DHW tank can not be enabled if under floor heating is set
as the priority.
