ALARM/WARNING CODES
Ordering No. Description
0.
Alarm! Supply fan malfunction.
• Determined depending on a specific configuration.
• By rpm: if the supply fan speed drops below 300 rpm for 30 seconds (configurable within a 5 to 120 second range).
• By discrete input: if the discrete input (ТAНО М1) remains open for 30 seconds (configurable within a 5 to 120 second range)
provided that the supply fan must be running.
1.
Alarm! Extract fan malfunction. Determined depending on a specific configuration.
• By rpm: if the extract fan speed drops below 300 rpm for 30 seconds (configurable within a 5 to 120 second range).
• By discrete input: if the discrete input (ТAНО М2) remains open for 30 seconds (configurable within a 5 to 120 second range)
provided that the extract fan must be running.
2.
Alarm! No outdoor air temperature sensor detected.
Determined if the heat exchanger freeze protection is active or the unit is configured with a bypass, a rotary heat exchanger, a cooler
or a water heater.
3.
Alarm! Short circuit of the outdoor air temperature sensor.
Determined if the heat exchanger freeze protection is active or the unit is configured with a bypass, a rotary heat exchanger, a cooler
or a water heater.
4.
Alarm! No supply air temperature sensor detected.
Determined in any unit configuration.
5.
Alarm! Short circuit of the supply air temperature sensor.
Determined in any unit configuration
6.
Alarm! No extract air temperature sensor detected.
Determined if the extract air temperature sensor is selected as the master sensor for temperature control provided that the main
heater or condensing unit are enabled. The alarm will also be determined irrespective of which sensor is selected for temperature
control if the bypass or rotary heat exchanger is enabled.
7.
Alarm! Short circuit of the extract air temperature sensor.
Determined if the extract air temperature sensor is selected as the master sensor for temperature control provided that the main
heater or condensing unit are enabled. The alarm will also be determined irrespective of which sensor is selected for temperature
control if the bypass or rotary heat exchanger is enabled.
8.
Alarm! No extract air temperature sensor detected.
Determined if the heat exchanger freeze protection is active.
9.
Alarm! Short circuit of the extract air temperature sensor.
Determined if the heat exchanger freeze protection is active.
10.
Alarm! Actuation of the protecting preheater thermostat.
Determined if the preheater is selected for protecting the heat exchanger from freezing (NKP IN).
11.
Alarm! Actuation of the protecting preheater thermostat.
Determined if electric or water heater is enabled as the main heater and the discreet input (NKD IN) is open.
12.
Alarm! Preheating cannot provide heat exchanger freezing protection.
Determined if the preheater is selected for protecting the heat exchanger from freezing and freezing danger warning has been active
for 30 minutes.
13.
Warning! Main humidity sensor is not detected.
Determined if the main humidity sensor is activated and its signal value is 0.
14.
Warning! Main CO
2
sensor is not detected.
Determined if: the main CO
2
sensor is activated and its signal value is 0.
15.
Warning! Main PM2.5 sensor is not detected.
Determined if the main PM2.5 sensor is activated and its signal value is 0.
16.
Warning! Main VOC sensor is not detected.
Determined if the main VOC sensor is activated and its signal value is 0.
17.
Warning! External humidity sensor is not detected.
Determined if the sensor has sent no feedback to the controller for 20 seconds while being active.
18.
Warning! External CO
2
sensor is not detected.
Determined if the sensor has sent no feedback to the controller for 20 seconds while being active.
19.
Warning! External PM2.5 sensor is not detected.
Determined if the sensor has sent no feedback to the controller for 20 seconds while being active.
20.
Warning! External VOC sensor is not detected.
Determined if the sensor has sent no feedback to the controller for 20 seconds while being active.
21.
Warning! Indoor air temperature is not detected!
Air management relies on the temperature sensor in the supply air duct.
Determined if no sensor data has been communicated from the control panel to the controller for 20 seconds if the sensor is selected
as the temperature control master sensor provided that the main heater, the bypass, the rotary heat exchanger or the condensing unit
are enabled.
22.
Warning! The threat of freezing heat exchanger.
Determined if the supply fan is enabled, the outdoor temperature drops below -3 ˚С and stays below -1 ˚С, and the extract air
temperature downstream of the heat exchanger drops below 2 ˚С and stays below 3 ˚С.
