4.9.2 Settings Heat pump*
Start at degree minute -60 (-900...-30)
The degree minute at which Heat Pump 1 (HP1) will
start is entered here. Degree minute calculation is used
only for System Types 1, 2 and 3.
Max primary flow HP diff °C 10 (3...20)
If the actual value for the primary flow is the same as the
setpoint plus the set value and the degree minutes are
less than the start value for the first heat pump (factory-
set to -60), the degree minutes are set to the start value
for the first heat pump.
If the actual value for the primary flow is greater than the
setpoint plus the set value and the degree minutes are
less than 0, the degree minutes are set to 0.
If the actual value for the primary flow is less than or
equal to the setpoint minus the set value, the degree
minutes are set to the start value for the first heat pump
(factory-set to -60).
Applies to System Types 1, 2 and 3.
Max primary flow HP Add. heat diff °C 14 (5...20)
If the actual value for the primary flow is less than or
equal to the setpoint minus the set value, the degree
minutes are set to the highest set start value for the
peak heat (factory-set to -500).
Applies to System Types 1, 2 and 3.
Diff between comp. -60 (-200...-30)
This menu defines the difference (measured in degree
minutes) at which the heat pumps will be started if
necessary. During incrementing/decrementing using a
smaller heat pump with lower output, half the set value
is counted.
Applies to System Types 1, 2 and 3.
Delay between comp. 30 (5...180)
The delay time between when two heat pumps can
start is set here. This value applies, for example, to the
amount of time that will pass before the third heat pump
can start, when the first and second heat pumps are
operating, and so on.
During incrementing/decrementing using a smaller heat
pump with lower output, half the set value is counted.
Applies to System Types 4-6.
*The number of possible heating circuits or heat pumps
that can be connected to the system varies depending
on the control system.
