Descriptions for each parameters are as following.
• Solar collector set temp
- Min temp : It is the minimum solar collector temperature at which the solar thermal system
can operate.
- Max temp : It is the maximum solar collector temperature at which the solar thermal system
can operate.
• TH on/off Variable, solar
- Temp on : It is the temperature difference between the current solar thermal temperature and
DHW tank temperature at which the solar thermal system operates.
- Temp off : It is the temperature difference between the current solar thermal temerature and
DHW tank temperature at which the solar thermal system stops.
- Example : If the current solar collector temperature is 80 °C and Temp on is set to 8 °C, the
solar thermal system operates when the DHW tank temperature is less than 72 °C.
In the same case, if Temp off is set to 2 °C, Solar Thermal System stops when
DHW temperature is 78 °C.
• DHW Set Temp
- Max : It is maximum temperature of DHW that can be reached by solar thermal system.
• Boost Heater
- Enable : DHW tank heater can be used when operating the Solar Thermal system.
- Disable : DHW tank heater cannot be used when operating the Solar Thermal system.
• Solar pump flush schedule
- It is the function to circulate the solar water pump intermittently for solar collector
temperature detection when the solar water pump does not operate for a long time. Turn on
to use this function.
• Solar Pump flush setting
- Oper.Cycle : When using the solar pump flush function, the solar water pump operates at the
set time.
- Oper.Time : When using the solar pump flush function, the solar water pump operates during
the set time.
