occurs, wind fan operates by starting delay timer, but during delay timer is
counting or after timer counting up if stop key is not pushed then wind fan continues in operation.
Error codes above shall be shown in case of original setting of controller parameter at ex-works.
There are various functions available with IN and OUT of outer control terminal of HAPcontroller.
Be cautious about error indication which might come from parameter modification not described in this
manual. Refer for more details to "HAP controller handling manual details division".
・When irregularity occurs, it power off to heater or to wind fan and heater. It lights on
irregular lamp and indicates error code responding to irregular conditions.
・If irregularity occurs once, irregular condition has been maintained and even irregulari-
ty has been solved, device will not work again. To release irregular conditions main-
tained, it is required to re-switch on after switching off.

Name
Irregularity Contents
Wind Fan
irregularity
In case that ampere to motor excesses maximum allowance volume due to
coil heating of wind fan, it is indicated. By this indication of code it puts off
to wind fan and heater. It puts ON out put of wind fan irregularity at outer
control terminal.
Irregularity 1 of tem-
perature control
Indication comes when temperature sensor set at outlet shows +20℃ com-
pared with set temperature.
By this indication of code it puts off to heater. and wind fan operation begins
with starting delay timer. It puts ON out put of irregularity 1 of temperature
control at outer control terminal.
Irregularity 2 of tem-
perature control
Indication comes when irregularity occurs in accordance with setting to catch
temperature irregularity by thermocouples connected with in put of
thermocouples-2 at outer control terminal.
By this indication of code it puts off to heater. and wind fan operation begins
with starting delay timer. It puts ON out put of irregularity 2 of temperature
control at outer control terminal.
Irregularity of thermo-
couples failure
Indication comes when thermocouples failure is detected. By this indication
it puts off to heater. and wind fan operation begins with starting delay timer.
It puts ON out put of irregularity 1 of temperature control at outer control ter-
minal if thermocouples set at outlet becomes failure, it puts ON out put of
irregularity 2 of temperature control at outer control terminal. If thermocou-
ples set at inlet at outer control terminal 2 becomes failure.
Over heat temperature
irregularity
In case that temperature in heater box excesses maximum allowance tem-
perature. Liquid expansive thermostat located in heater box becomes ON
and indicates irregularity. By this indication it puts off to heater. and wind fan
operation begins with starting delay timer. it puts ON out put of over heat at
outer control terminal.
Irregularity of suction
air temperature
In case that suction air temperature becomes high and excesses maximum
allowance temperature, Liquid expansive thermostat located in outlet of wind
fan becomes ON, it indicates irregularity of suction air temperature.
By this indication it puts off to heater. and wind fan operation begins with
starting delay timer it puts ON out put of over heat at outer control terminal.
Irregularity of outer
over heat temperature
It is indicated when irregularity occurs through connection with in put of irreg-
ularity of outer over heat. By this indication it puts off to heater. and wind fan
operation begins with starting delay timer It puts ON out put of over heat at
outer control terminal.
