09. If errors occur

The Sanyo CO2 Eco is constructed for high comfort, good reliability and long
life length. Below you find hints how to solve different problems if they occur.
If something goes wrong, contact your installer that was responsible for the
installation. He will contact the dealer if he judges it to be a material or
factory error. Use the serial number for this product in every contact with the
dealer or manufacturer.
- check if the outgoing sanitary hot water temperature from the tank unit is ok or not
(before the thermostatic temperature limiter).
- check the thermostatic temperature limiter for the sanitary hot water mounted on the
tank unit.
- check the thermostatic temperature valve in the shower.
- check the tank temperature in the contro

If the room temperature is too low, please check:
- that the radiator thermostatic valves are full open, and that the radiator
surface temperatures are even. It is important that the radiator system
works correctly for an optimal operation.
Take the air out of the radiator system.

- that radiator thermostatic valves don t disturb the room sensor.
- that no other heat sources disturb the room sensor.
- that the mixing valve isn t pushed in manual position.

reason making the temperature to high. he system has to be reset manually after
such failure: shut off all voltage to the tank unit with the main switch, and put it on
ppears repeated times, search for the reason of the failure.
