If, before the delay time has elapsed, the disinfection
conditions are fulfi lled by solar loading, thermal disin-
fection is considered complete and a new monitoring
period begins.
If the starting time is adjusted to 00:00 (factory set-
ting), the delay function is inactive.
When thermal disinfection is activated, different dis-
play channels appear depending on the current status
of the function (see also p. 42):
CDIS - countdown of the monitoring period
DDIS - countdown of the disinfection period
TDIS - substitutes TSTT during the disinfection period
SDIS - displays the adjusted starting time (fl ashing)
during the delay time after the monitoring pe-
riod has ended
OTDIS / TSDIS
Sensor thermal disinfection
Adjustment range: 2,3,4,5
Factory setting: system dependent
For this function, free sensors at an appropriate posi-
tion can be selected.
OTDIS / RDIS
Relay thermal disinfection
Adjustment range: 2, 3, 4
Factory setting: system dependent
The relay for the thermal disinfection function can be
selected.
Parallel relay
OPARR / PARRE
Parallel relay
Adjustment range 2, 3, 4
Factory setting: 2
With this function, e. g. a valve can be controlled in
parallel to the pump via a separate relay PARRE.
If solar loading takes place (R1 and/or R2) or if a solar
function is active, the relay selected will be energized.
The parallel relay can also be energized inversely
(INVER).
Note
If R1 and/or R2 are in the manual mode, the
selected parallel relay will not be energized.
Energy metering
OHQM
Energy metering
Adjustment range: OFF / ON
Factory setting: OFF
OHQM / FTYPE
Flow rate detection type
Selection: 1, 2
Factory setting : 1
The energy metering can be carried out in 2 different
ways (see below): without fl owmeter (using a fi xed
fl ow rate value) or with a V40 fl owmeter.
