Return flow increase option
Used for buffer discharging with the objective of
providing heat for the heating system. The heating
circuit return is preheated via the buffer as soon as
this is higher by a definable temperature difference
and supplied in the boiler return and possibly post-
heated using the heat source. CAUTION: storage
tank type (08-055) must be at 1 = heat storage tank!
TxO > THR + switch-on difference (08-080) & TxO <
maximum temperature return increase (07-008) =
UHR active (hysteresis 2K)
TxO < THR + switch-off difference (08-081) or TxO
> maximum temperature for the return increase
(07-008) = function blocked
