Basics of instantaneous water heater (function)
To configure an instantaneous water heater, the DHW sensor connected to terminal
B3/B38 must be parameterized as sensor B38. For that, use parameter DHW sensor
(5730) and select DHW outlet sensor B38.
Parameter DHW controlling element (5731) is used to select the type of controlling
element (diverting valve or charging pump). Control of this controlling element must be
assigned to at least one output (QX1, QX2, QX3, QX4/WX1) (parameters Relay output
QX1 (5890), Relay output QX2 (5891), Relay output QX3 (5892), Relay output QX4
(5894)). Here, select Instant WH ctrl element Q34. For the control of a diverting valve,
output QX3 has a changeover contact.
Parameter Aqua booster (5550) is used to determine whether there is an aqua booster.
