13.4. RELAY oUtPUtS
all relays have a 1a maximum loading at 250Vac. the outputs are 230V except for the n07 output for the boiler.
the output status can be seen in the menu i-o -> do. the status is 1 when the relay contact is closed and 0 when
the relay contact is open.

13.5. DIGItAL INPUtS
the inputs use a low voltage signal difficult to measure with a voltmeter. We recommend using the display to check
the input status.
Menu i-o -> di . the status is 1 when the contact connected to the input is closed and 0 when it is open.
For example when the fan internal overload switch is closed the display will show "6-1" to show the status; as the
alarm contact is normally closed this is normal and shows that the fan motor is not overheating.

13.6. ANALoGUE oUPUt
the Y3 output is used to control the fan speed. the Y1 is a PWM type so it is not possible to measure the value
with a voltmeter.
the fan speed status is available on the display in the "i-o" menu. the value given is a percentage of the maximum
possible speed for any given model.
13.7. KWH MEtER
the compressor driver measures the current used. this information is used to estimate the power consumption.
an estimation of fan and pump current is added to the compressor current. the output is given in kWh kilowatt
hours. note that this value must be considered as estimation only; the true value will vary depending on voltage
and auxiliary power use.
the voltage is set at 225V by default, this parameter can be changed at h26.
