The reference sensor is located in front of the valve or the
pump respectively. The default is sensor 3, but this can be
changed using this menu item.
This function is used to link loading circuits that are sepa-
rated by an external heat exchanger.
The heat exchanger relay is activated if the temperature at
the reference sensor exceeds the store temperature by the
adjusted value "HE DTon" and if the switch-on conditions for
store loading (see "store loading") are fulfilled.
The relay is switched-off if this temperature difference falls
below the adjusted switch-off difference HE-DToff.
In contrast to the bypass function, a differential regulation
between "T-HE" ("Sen. Ext. HE") and "Tst" can be carried
out by means of the heat exchanger relay.
The reference sensor can be arbitrarily allocated.
In systems in which stores are equipped with their own
loading pumps, the relay "external heat exchanger" controls
the primary circuit pump.
This function helps overcome the non-ideal sensor position
with some tube collectors.
This function operates within a given time frame ("tube
init" and "tube-final"). It activates the collector circuit
pump for 30 seconds (adjustable via the parameter "tube-
run") every 30 minutes (adjustable via the parameter "tube
col") in order to compensate for the delayed temperature
measurement.
If the collector sensor is defective or the collector is blocked,
this function is suppressed or switched-off.
The collector circuit is operated at minimum pump speed.
2-collector systems Both collectors are operated independently from each other
by means of this function.
If a store is being loaded by one collector, the other one is
nevertheless operated after the adjusted standstill time.
If store loading is carried out by one collector, the other one
is nevertheless operated after the adjusted standstill time.
This means the pump speed may reduce briefly to the
minimum as the normal pump speed is ignored by the
controller
