Check remote controller operation and temperature setting

Check function code setting with the function code table.

Check backup heater and bimetal thermostat. Check selection of equipment.

Check whether temperature sensor is installed at the normal position.

Check power supply wiring.

Check DIP switch setting on the Hydro Unit board. Check the setting with the function code table.

Release air completely according to the procedure.

Set hydraulic pressure considering pipe height, and replenish water until manometer shows a value of set hydraulic pressure or more.

Clean the strainer.

Widen water path to the hydro unit or adopt a bypass valve.

Check wiring and parts.

Set hydraulic pressure considering pipe height, and replenish water until manometer shows a value of set hydraulic pressure or more.

Check expansion tank capacity compared to total water amount. If it is insufficient, install another expansion tank.

Check the air pressure.
