Why does the current temperature setpoint deviate from
the values we have entered under “Room/extract air ctrl”?
• If the unit is equipped with room and extract air con-
trol, the temperature is controlled by two controllers
(a room/extract air controller and a controller for
the supply air temperature). The setpoint entered on
the room/extract air controller is used to generate the
setpoint on the supply air controller. Consequently,
the setpoint for the supply air temperature will vary
with the energy requirement in the room or extract air.
• The function Summer/Winter compensation may be
activated. Compensation displaces the setpoint de-
pending on the prevailing outdoor temperature.
• If the selected setpoints lie outside the permitted
range, a setpoint corresponding to the maximum and
minimum limits will be obtained (depending on
whether the selected setpoint is too high or too low).
The outdoor temperature is not displayed.
Is something wrong?
• Check that the outdoor sensor has been activated on
the controller.
MAIN INDEX CONFIGURATION CONFIGURATION 1
Operation
How do I set the same schedule for every day?
• Use the copy function, Copy Schedule, to copy the
Monday schedule to Tuesday to Friday.
How can you set the scheduler so that the unit is
switched off on Saturdays and Sundays?
• Set the first scheduler for Saturday and Sunday to Off
at 00:00 for example. Specify the following schedulers
for Saturday and Sunday using asterisks, *.
How does start up work if I have pressure controlled
supply air with slave controlled extract air?
• The extract air fan regulates towards a fixed setpoint
until the supply air fan has started. This value can be
changed on the controller.
Miscellaneous
Why is the terminal block Fire strapped?
• On delivery the contact function for the fire alarm is
normally closed (NC). Thus the unit would generate
an alarm if the inputs were not strapped.
After the cover has been fitted on the control panel several
gaps are visible in the cellular plastic strip. Is the lead-in
really sealed?
• The cellular plastic strip is of a semi-elastic type, with
both open and closed cells. It will slowly adapt to the
shape of the cables. If the gaps should remain after a
few days the cables should be moved sideways slightly.
There is no space for the incoming power supply on
terminal blocks L1, L2, L2 and N?
• The terminal block for power units up to 5.5 kW is
intended for cable of a maximum 4 mm 2 .
Why is there no main circuit breaker?
• The unit must be equipped with an external load
interrupter on the incoming supply.
What does alarm class C mean?
• The alarm is only shown on the display.
The electric heater is tripped by the automatic thermal
overload protection. How do I rectify the fault?
• Air supply temperature is too high. Reduce the set-
point or increase the flow.
The air handling unit is switched off yet the pump to the
heating coil is running. Is something wrong?
• If the temperature of the return water from the heating
coil is low, the frost protection controller runs the
pump to the heating coil, so that the coil does not risk
freezing when the unit starts.
• The pump is exercised every Monday at 12:00 or is set
to continuous operation.
The air handling unit is switched off yet the pump to the
cooling coil is running. Is something wrong?
• The pump is exercised every Monday at 12:00 or is set
to continuous operation.
