∆T Solar
Switch on/switch off temperature difference for sensor X:
If the temperature difference ∆T Solar between the reference sensors is exceeded and the other conditions are fulfilled,
the controller will turn on the pump/valve on the corresponding relay. If the temperature difference falls to ∆T Off, the
pump/valve will be turned off again.
Tmax Storage
Switch off temperature at sensor X:
If this value is exceeded at the specified sensor, the controller turn off the affiliated pump or the valve. If this value on the
sensor is undershot and the other conditions are fulfilled, the controller will turn on the pump or the valve.
b
Temperature values which are set too high can lead to scalding or damage to the system. Scalding protection must
be provided by the customer!
Starting aid
For some solar systems, in particular for vacuum tube collectors, the measurement recording on the collector sensors
may be too slow or imprecise, because the sensor is often not on the warmest spot. With an activated starting aid, the
following procedure occurs: If the temperature on the collector sensor increases within a minute by the value defined un-
der “increase”, the solar circulation pump will be turned on for the set “purging time” so that the medium to be measured
is transported to the collector sensor. If there is still no normal switching condition through this, there will be a 5 minute
block time for the start wizard function.
b
This function should only be activated by a technician if problems occur with the measurement recording. Observe
in particular the instructions from the collector manufacturer.
The menus "Purging time" and "Increase" are only displayed when the starting aid function is set to "On".
Purging time
If the temperature on the collector sensor increases within a minute by the value defined under “increase”, the solar circu-
lation pump will be turned on for the set “purging time” so that the medium to be measured is transported to the collector
sensor. If the set ∆T is not reached, a 5-minute circulation pause time for the starting aid function will apply.
Increase
If the temperature at the collector reaches within a minute the value defined, the solar pump is turned on for the duration
of the purging time.
System protection
Priority protection function
The system protection should prevent an overheating of the components installed in the system through the forced shut
down of the solar circulation pump. Activate or deactivate function
SP Ton/off
If the value “SP Ton” is exceeded at the collector, the pump is switched off after 60 seconds and will not be switched on
again, in order to protect the collector e.g. from steam hammering. The pump will only be switched on again, when the
collector temperature falls below “SP Toff”.
Parallel operation V1/V2
Switches the selected relay in parallel with the 0-10 V / PMW output V1/V2.
Switch parallel operation on, off or inverted.
Delay
The assigned relay switches on the delay set here later than V1/V2.
Follow-up time
The assigned relay switched on for the time set here longer than V1/V2.
Always on
The selected relay is always switched on.
Activate or deactivate "Always on"
