D 6.4 - Collector protection
If „CP Ton” is exceeded at the collector sensor, the pump is switched on in order to cool the collector down.
The pump turns off when the collector temperature falls below „CP Toff” or the temperature „CP Tmax storage”
is exceeded in the storage or pool. In systems with 2 storage tanks only the lower-priority tank or pool is used
for collector cooling.
Collector protection - Setting range: On, Off / default setting: Off
Settings range: CP Ton 60 °C to 150 °C / Default: 110 °C
Settings range: CP Toff 50 °C to CP Ton -5 °C / default setting: 100 °C
Settings range: CP Tmax storage 0 °C to 140 °C / default setting: 90 °C
When collector protection is active, the storage or pool may get heated to a high temperature!
D 6.4.1 - Cooling functions
menu 6.4.1
The hydraulic variants are set in menu „7.1 Program selection“
Hydraulic Variant D.14 Solar + cooling 1:
If „CProt Ton” is exceeded at S1 (collector), the cooler at R2 is switched on until the temperature drops to
„CProt Toff”. If the storage tank exceeds „CProt Tmax storage”, the pump at R1 is switched off.
Hydraulic Variant D.15 Solar + cooling 2:
If „CProt Ton“ is exceeded at S1, the cooler at R2 is switched on. If the storage tank exceeds „CProt Tmax
storage“, R1 is switched off with R2 still running to keep on cooling. If the temperature at S1 drops to „CProt
Toff“, cooling is switched off.
Hydraulic Variant D.16 Solar + cooling 3:
If „CProt Ton“ is exceeded at S1, the pump at R1 is switched on to cool the collector by heating up the storage
tank.
If the storage tank exceeds „CProt Tmax storage“, R1 pump is switched off. Once the storage tank at S3
exceeds Tset S3, cooling at R2 is switched on until „TsetS3“- hysteresis is reached.
D 6.5 - Col.- Alarm menu 6.5
If this temperature is exceeded at the collector sensor when the solar pump is on, a warning is triggered. A red
LED starts flashing and a warning message is shown in the display.
Setting range: Collector alarm off, on / default setting: off
Setting range: Col. alarm 60 °C to 300 °C / Default setting: 150 °C
