the supply impedance.
Sensor or controller fault
Replace the sensor or the controller.
Some digital input is not working
The signal from the output
is not a supported impulse
signal.
Use only output potential-free contacts
(relay outputs or an optoisolator open
collector).
The open collector output
is connected inversely.
Change the terminals at the device
output.
Controller fault
Replace the controller.
The TEST button cannot switch on
some connected device
The device is not
connected or it is
connected incorrectly.
Check the connection of the relevant
device and switch on the relevant circuit
breaker or fuse switch disconnector.
The device is connected
correctly but it cannot be
switched on.
Check if the device does not have, for
example, built-in thermal protection.
The output LED is not on
or another controller fault.
Replace the controller.
The outputs do not switch on as
they should
The output is not activated Activate the output in the relevant control
block.
The control block is not
activated
Activate the control block and wait for the
conditions to be met for activating the
output.
Incorrectly configured
control block
Check the configuration of the control
block.
The external outputs do not switch
on the connected solid state relays
(SSR)
Incorrect connection of
the relay
Check that the connection is correct and
check the polarity of the terminals, it must
always be observed.
Incompatible relay
Always use a relay which switches on at
zero and which is operated by low direct-
current voltage >4VDC.
Controller fault
Replace the controller.
Application firmware cannot be
loaded even after repeated
attempts
Incorrect or damaged file
*.scf
Load only original firmware for the
Heating Control device.
Communication errors
Make sure that there are no problems in
the connection of the PC to the controller
or in the PC itself (viruses, etc.).
Controller fault
Replace the controller.
The red LED is flashing
An error status has been
detected
Follow the instructions in the Chapter LED
Status.
Statistics do not correspond to
reality
It is not a fault
The data is only for reference and is based
on the measured data.
Statistics have been erased
suddenly
It is not a fault
The date in the controller has been
changed or there was a power failure
while the history was being written in the
EEPROM memory.
House heating is inadequate
The heat pump does not
have the necessary power
Have the heat pump functionality and
amount of refrigerant in the circuit
checked by the refrigeration service.
