11.3 How to Cope with Abnormal Test Run
* 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 )
Item
Phenomenon
Cause
Checkpoint and resolution
Whether
heat water
is supplied
CH24
When connecting the flow switch,
heat-sourced water doesn’t flow or the
amount of its flow lacks due to the checked
error related to heat-sourced water.
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.)
CH32
Heat water not supplied or flow rate is
insufficient
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.)
CH34
Heat water not supplied or flow rate is
insufficient (During cooling)
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.)
CH180
Heat water not supplied or flow rate is
insufficient (During heating)
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.)
