Coding
Coding in the Delivered Condition
Speed control solar circuit pump
02:0 Solar circuit pump (multi stage) without speed
control by solar control module SM1.
DHW tank Maximum Temperature
08:60 The solar circuit pump stops when the actual
DHW temperature reaches the maximum DHW
tank temperature 140ºF (60°C).
Stagnation Time Reduction
0A:5 To protect system components and heat transfer
medium:
the speed of the solar circuit pump is reduced
if the actual DHW temperature is 5 K below
the maximum DHW tank temperature
Flow Rate Solar Circuit
0F:70 The solar circuit flow rate at maximum pump
speed is 7 L/min.
Extended Solar Control Functions
20:0 No extended control functions enabled.
Possible Change
02:1 Solar circuit pump (multi stage) is speed-
controlled with wave pack control.
