10.3 How to Cope with Abnormal Test Run

The phenomena from main component failure

Item Phenomenon
When connecting the flow switch,
heat-sourced water doesn't flow or
CH24
the amount of its flow lacks due to
the checked error related to heat-
sourced water.
Heat water not supplied or flow
Whether
CH32
rate is insufficient
heat water
is supplied
Heat water not supplied or flow
CH34
rate is insufficient(During cooling)
Heat water not supplied or flow
rate is insufficient (During
CH180
heating)
When CH24 or CH180 error occurs during the test operation of the heater, the inside of the panel heat exchanger may be
partially frozen and therefore, be sure to get rid of its cause and then, re-operate the device.
(The root cause of partial freezing: The lack of flow of heat-sourced water, suspension of water, lack of cooling medium,
infiltration of foreign substance inside of panel heat exchanger )

Cause
Check whether the heat source water supply pump is operating.
Check whether the heat source water supply pipe is clogged.
(Clean strainer, valve locked, valve issue, air trapped etc.)
Check whether the flow switch is normal condition.
(Flow switch problem, arbitrary control, disconnection etc.)
Check whether heat source water supply pump is operating.
Check whether the heat source water supply pipe is clogged.
(Clean strainer, valve locked, valve issue, air trapped etc.)
Check whether heat source water supply pump is operating.
