Function Codes - Hydro Kit Medium Temperature
temperature control Parameter setting for Water Heating operation Hydro
Kit Medium temperature
function Codes 28 and 29
These two functional codes set control parameters for the sanitary
water heating operation.
• 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 as '5' and Value #2 is set as '80',
the water tank heating will be started when the water tank
temperature is below 75°C (167°F).
• 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 53°C (127°F). Water tank heating
will kick on when water temperature is below 50°C (122°F).
— 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.

If the Hot Water DHW icon is displayed on the remote controller,
DHW is enabled. It can be enabled via manual button input or
scheduled programming.
function Code 2B
This function code sets DHW heating timers. Determine time dura-
tion, 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 60 for examples of a timing sequence chart.
