HVAC Products 6 The settings in detail 23. November 2007
If none of the Hx inputs is used to release the swimming pool, the swimming pool
priority is determined by the parameter setting. The swimming pool is always enabled
for solar heating.
If the swimming pool is enabled via
one of the Hx inputs, swimming pool priority is
equivalent to the parameter setting. Solar heating must now be enabled via the Hx
input.
If
2 Hx inputs are used to enable the swimming pool, the swimming pool is given priority
when both Hx inputs are enabled. If only one of the Hx inputs is enabled, the swimming
pool priority is determined by the parameter setting. If none of the Hx inputs is enabled,
solar heating of the swimming pool is disabled.

The primary controller makes it possible to mix the flow,
aimed at obtaining flow temperatures for heating / cooling
groups with setpoints higher or lower than those of the
common flow.
The system pump can be used to overcome the pressure
drop to remote heating / cooling groups.
