If none of the Hx inputs is used to release the swimming pool, the swimming pool
priority is determined by the parameter setting. For solar heating, the swimming pool is
always released.
If the swimming pool is enabled via one of the Hx inputs, swimming pool priority is
equivalent to the parameter setting. For solar heating, release at input Hx is now
required.
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.
Line no. Operating line
2080 With solar integration
This setting is made to indicate whether the swimming pool can be charged by solar
energy.

Before buffer
After buffer
If the plant uses a buffer storage tank, it is to be set here whether – hydraulically
speaking – the primary controller or the system pump is installed upstream of or
downstream from the buffer storage tank.

6.12 Heat pump

The heat pump draws energy from the environment (brine, water or air) and delivers it
to the heating system at a higher temperature level. If the heat pump is equipped with a
process reversing valve, it can also be used for active cooling. Also, brine-to-water and
water-to-water heat pumps can be employed for passive cooling.

6 The settings in detail
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.
