(valve energized in DHW position)
2 = Diverting Valve NC 2-points
(valve de-energized in DHW position)
3 = Dedicated DHW Circulator or Pump
2. Maximum runtime
If this parameter is configured to -1, DHW Runtime is ignored.
3. DHW days schedule

5. Summer mode delay
The summer mode is set when the Summer Mode
switch is closed.
Summer Mode is set to "On" if OAT is above
Summer Mode OAT Threshold [sum_oat] for at
least the period of a given delay (sum_on).
Summer Mode is reset if OAT goes below
Summer
Mode OAT Threshold [sum_oat] minus 2 K for at
least the period of a given delay (sum_off).
6. DHW tank sensor type
0 = DHW Thermostat (thermal switch)
1 = DHW Sensor (thermistor 10 KΩ)
2 = DHW Sensor (thermistor 5 KΩ)
3 = DHW Sensor (thermistor 3 KΩ)
7. DHW tank delta T
DHW mode is requested if Tank Water Temperature
goes below DHW Setpoint [dhw_stp] minus DHW
Tank Delta T [dhw_dt].
