13. Solar connection
Set when solar water heater is installed.
Setting include items below.
Set either buffer tank or DHW tank for connection with solar water heater.
①
Set temperature difference between solar panel thermistor and buffer tank or DHW tank
②
thermistor to operate the solar pump.
Set temperature difference between solar panel thermistor and buffer tank or DHW tank
③
thermistor to stop the solar pump.
Anti-freezing operation start temperature (please change setting based on usage of glycol.)
④
Solar pump stop operation when it exceeds high limit temperature (when tank temperature exceed designated temperature (70~90°C))

14. External Error signal
Set when external error display unit is installed.
Turn on Dry Contact SW when error happened.
(NOTE) Does not display when there is no Optional PCB.
When error occurs, error signal will be ON.
After turn off "close" from the display, error signal will still remain ON.
