Troubleshooting - Warning, limitation and alarms
Limit
Connection delay
Delayed output connection after restart after power failure.
Upon restart after power loss, up to 6 kW is connected immediately if necessary.
In service mode, the delay can be accelerated, see "Service level" row 2.
The delay can be permanently removed, see "Advanced Service level", row 14.
The load guard limits
Green indicator flashes. The load guard limits.
See "Service level" rows 3 and 4.
External restriction /
blocking
Green indicator flashes. External limit.
Blocking or restriction via external 0-10V signal, see "User level" row 3.
Manual operation
Manual connection of output stages and circulation pump, see "Advanced Service level"
rows 18-20.
ECO mode
Green indicator flashes. ECO function is active, see "User level" row 12.
Warning - yellow indicator flashing
The display shows current warnings if no stop alarms occur. The information remains until OK is pressed and the cause
has been resolved.
High temperature
around power
circuit board
Temperature > 45°C.
Yellow indicator goes off at temperature below 42°C, the warning is acknowledged
with OK.
All connected output steps out at temperatures > 55°C, output can be stepped back
in at temperatures < 45°C, see "Advanced service level" row 24.
High boiler temperature
Over Temperature.
Yellow indicator goes off when temperature has fallen below the limit and the warning
is acknowledged with OK. All connected output steps out and steps in again only when
the temperature has dropped below the limit. Selectable in "Advanced Service level"
rows 16 and 7.
Low boiler temperature
Boiler temperature lower than 7°C.
The electric flow heater's temperature must be no lower than 7°C during operation,
regardless of the selected setpoint.
If external blocking / external control is active, the electric flow heater is
NOT
allowed
to step in output.
If the load guard restricts, the electric flow heater is
NOT
allowed to step in output.
Outdoor sensor
Incorrect value, interruption, disconnected sensor or short-circuit.
Control assumes 0°C outdoor temperature.
Room device
Incorrect value, interruption / short circuit of the sensor and / or disconnected room unit.
The unit is disconnected from the control until the alarm is acknowledged and the room
unit is repaired.
Room unit, adjustment
Incorrect value, interruption / short circuit or disconnection of the room unit. The unit
is disconnected from the control until the alarm is acknowledged and the room unit
is repaired.
Alarm - red indicator flashes: the electric flow heater is blocked
Display window shows current alarms. The information remains until the cause is corrected and OK is pressed
Boiler temperature
sensor
Incorrect value or interruption / short circuit on sensor.
Temperature sensor
on circuit board
Incorrect value or interruption / short circuit on sensor.
Low boiler temperature
Boiler blocked due to a boiler temperature lower than 3°C.
Overheating protection
triggered
All output disconnected, the circulation pump is still in operation.
Low supply voltage
Low supply voltage to electronic components, all output disconnected, the circulation
pump is switched off.
