As a result of the tap signal (dV) the load circulation is
started and the fresh water is heated up to the adjusted
temperature.
The active function is displayed.
If the measured differential between the retrun flow tem-
perature (T-R) and the store referential temperature (T-St)
exceeds the adjusted temperature (∆T-rD ON) relay V-R will
be switched on.
It will be switched off again if the load circuit is not in ope-
ration or the adjusted switch-off differential (∆t-RD off) is
underrun.
In order to secure a proper start up of the pumps with
lower pump levels as well as the pumps with longer tap
pauses it is necessary to activate the pump regularly, e.g.
every four hours (during the day [6:00 a.m. to 8 p.m.] and
only if the tapping wasn't done in the meantime).
The active function is displayed.
If there is a sensor or a controller error, the error relay will
drop out.The relay for the error report can be adjusted
(R4 and/or R5).This function can be used for an additional
external display.
If the primary circuit is set up (processing of drinking wa-
ter), the relay is switched on. The relays for the operation
indication can be adjusted (R4 and/or R5).
This function can be used for an additional external dis-
play.
Defective sensors are displayed.
