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. Yellow Indication is solid when a warning is acknowledged with "OK", while the cause remains.
ot.1
High temperature of power circuit board.
Temperature > 45°C, yellow indication goes out at temperature below 42°C.
All connected output steps out at temperatures > 55°C, output can be stepped back in at temperatures < 45°C.
See menu “Advanced Service Level” row 27.
ot.2
Boiler temperature above installed maximum limit.
All connected output steps out and steps in again only when the temperature has dropped below the limit.
See the menus "Service Level" in row 18 and "Advanced Service Level" in rows 20 and 21.
ot.3
Boiler temperature lower than 7°C.
The boiler temperature shall exceed 7°C during operation, regardless of the set point.
If external blocking/external control is active, the boiler is NOT allowed to step in output.
ot.4
Outdoor temperature sensor.
Incorrect value, interruption/short circuit or disconnection of the room unit.
UTK assumes the outside temperature is 0°C until the sensor is exchanged or reconnected.
ot.5
Room unit, temperature sensor.
Incorrect value, interruption/short circuit of the sensor and/or disconnected room unit.
The unit is disconnected from the regulator until the alarm is acknowledged and the room unit is fixed
ot.6
Room unit, adjustment.
Incorrect value, interruption/short circuit or disconnection of the room unit.
The unit is disconnected from the regulator until the alarm is acknowledged and the room unit is fixed.
ot.7
Temperature sensor on power circuit board.
Incorrect value or interruption/short circuit.
As a temporary solution the regulation will be carried out without the monitoring of the internal temperature.
ot.8
Low water level in the boiler.
When there is a low water level in the boiler the power is blocked and the circulation pump is stopped. The regula-
tion is resumed when the water level is restored. The warning remains until it is acknowledged with “OK”.
Limitations - Green indication flashes
b.03
Indicates during operation with UTK that the alternative temperature applies.
With a fixed setpoint, external blocking prevents power connection. See “Service level” row 12.
b.04
Test mode, connection of power steps, circulation pump and buzzer alarm. See menu “Advanced Service Level”
rows 23 - 26
ECO
ECO – function selected in the menu. See menu “User Level” row 8
Alarm - Red indication flashes - Boiler blocked
Display window shows current alarms. The information remains and the buzzer sounds until “OK” is pressed and the reason
for the alarm has been corrected.
F.01
Boiler temperature sensor, incorrect value, interruption or short circuit.
F.02
Overheating protection triggered
F.03
Boiler temperature lower than 3°C. The boiler is blocked. Boiler temperature below 3°C - Freezing protection
F.06
Low supply voltage to electronic components, all output disconnected, the circulation pump is switched off.
