2-collector systems:
collector blocked
Pump speed is controlled according to collector tempera-
ture rather than (usual) temperature difference. The aim is
to maintain constant collector temperature, adjustable with
parameter "Tcolset".
If the solar circuit pump is switched-on, this relay is activated
in parallel.
In 2-collector systems which are working with 2 pumps, the
parallel relay is activated if one of the 2 pumps is activated.
If the irradiation exceeds the adjusted value CS-bypass, the
collector circuit is operated. It is switched off when the
irradiation has fallen below the value „CS-bypass" for at
least 2 minutes.
The collector circuit is operated with minimum pump
speed.
If a loading of the stores is carried out in these systems, the
function is switched-off.
This function is activated if a previously selected solar store
(parameter designation: "AH suppress." in the menu solar
expert) is being loaded.
Solar loading means that store loading is only carried out for
energy supply and not for cooling purposes etc.
At high collector temperatures (depending on system pres-
sure or antifreeze concentration etc.) the systems is shut
off. This means that solar loading is not possible.
If the adjusted temperature threshold „Tcolsec" is excee-
ded, the corresponding collector will no longer be used for
loading.
A collector is considered to be blocked, if either the sensor
is defective or the emergency shutdown temperature is
reached.
