HVAC Products Swimming pool 23. August 2007
Excess heat draw can be triggered by the following functions:
Inputs H1, H2, H3 or EX2
Storage tank recooling
Solid fuel boiler excess heat draw
When dissipation of excess heat is activated, it can be drawn by space heating. This
can be adjusted separately for each heating circuit.
If there is a buffer storage tank, this defines whether the H1/H2/H3 circuit can draw
heat from it.
When using alternative heat sources, the buffer storage tank temperature is used as a
control criterion for the release of additional heat sources.
This defines whether the H1/H2/H3 circuit receives its heat via the primary controller or
with the help of the system pump (depending on the type of plant).
2-pipe system
The cooling circuit with Hx and the heating circuits request cooling/heating from the
same circuit.
4-pipe system
The cooling circuit with Hx and the heating circuits demand cooling/heating from
separate circuits.
6.10 Swimming pool
Setpoints
Line no. Operating line
2055 Setpoint solar heating
2056 Setpoint source heating
When using solar energy, the swimming pool is heated up until this setpoint is reached.
The protective collector overtemperature function can reactivate the collector pump
until the maximum swimming pool temperature is reached.
When using the heat source, the swimming pool is heated up until this setpoint is
reached.
Priority
Line no. Operating line
2065 Charging priority solar
No:
Swimming pool heating through solar charging does not give consideration to any
priorities. If the storage tank charging priority (operating line 3822) is also deactivated,
the swimming pool is heated alternately with the storage tanks, the temperature
increase being 5 °C.
Yes:
Swimming pool heating through solar charging is given priority. This also applies if a
storage tank with charging priority (operating line 3822) would have to prefer other heat
exchangers.
If no Hx inputs are used to enable the swimming pool, the swimming pool priority is
determined by the parameter setting. The swimming pool is always enabled for solar
heating.
