Okofen PE 08 Operating Manual page 99

Solar settings
In the menu item measuring values no settings can be adjusted.
Measuring values and adjsuted settings are displayed.
The menu item Circuit 1 has following sub menu items:
• Op Mode
• ACC Temp Max
• ACC Hysteresis
• Collector Hyst On
• Collector Hyst Off
• Scavening
• Prio
• Display name
In this sub menu customer-specific adjustments can be set.
Therefore detailed information is to be fund in the user Manual for the End User
Settings for the Service technician:
If the temperature of the limit sensor is higher than the set temperature max, the so-
lar circuit pump switches off.
If the collector reaches the collector overheating temperature, the solar pump turns
off.
The solar circuit pump switches on again when the collector temperature falls be-
low the Coll Overheating minus Coll Overheating Hyst temperature.
You can choose for every solar circuit between solar pump and diverter valve.
Note:
If the diverter valve is chosen, the speed controller, pump type and parallel ope-
ration are hidden.
The menu Pumptype contains the following entries:
Asynchronus: Asynchronus pump – direct output 230VAC on/off
Async.Regulated: Asynchronus pump – pulsed output 230VAC
Heating Efficient: PWM1 - PWM signal inverted
Solar Efficient: PWM2 - PWM direct signal
Note:
If using a high-efficiency pump as accumulator pump, the pump of solar circuit
2 cann't be speed-regulated.
Wrong selection of the pump type can cause material
damage.
