Troubleshooting

Safety thermostat in electrical heater 

(optional equipment)

If an error occurs on an electrical heater, the safety ther-

mostat will disconnect. 

The heater is equipped with a fire thermostat that auto

-

matically cuts off the power supply, if the temperature 

exceeds 80 °C. If the temperature decreases, the heater 

automatically re-engages.

As an additional security there is a built-in thermal cut-out, 

which disengages if the temperature exceeds 110 °C. Re-

engaging must be done manually.

Does not apply to PTC electrical heaters.

The system is not running 

Unit stopped

Possible error:

•  Fuse in main board has blown, no power to unit.

•  One of the fuses on the circuit board of the unit is-

blown.

•  Loose wire, no power to unit.

•  Loose wire between unit and control panel.

•  Faulty or incorrectly set week program.

•  Filter timer has switched the system off.

Condensed water is leaking from the unit

Possible error:

•  Condensation outlet blocked by dirt.

•  The condensation outlet is not adequately protected 

against freezing at low outdoor temperatures.

Air faults

No supply air:

Possible error:

•  Faulty supply air fan

• 

Clogged supply air fi lter

•  Clogged fresh air grill due to dirt and leaves during the 

fall and snow and ice during the winter.

•  Fuse on the circuit board is blown.

•  The unit is in defrost mode (supply air fan stops)

•  Incorrect value set in User menu item 2.

No extract air:

Possible error:

•  Faulty extract air fan

• 

Clogged extract air fi lter.

•  Fuse on the circuit board is blown

Cold supply air:

Possible error:

•  Clogged heat changer.

•  Faulty extract air fan.

• 

Clogged extract air filter.

•  Electrical reheater is disconnected at the over heat-

ing thermostat (only units with electrical reheater 

installed).

•  Air in the heating pipes, faulty thermostat / motorvalve, 

incorrect setting of control panel.

Within the guarantee period (0-2 years):

 

The installer from whom you have bought the system. 

After the guarantee period (2 years ->):

 

The installer from whom you have bought the system or 

the Genvex service department (+45 7353 2765). 

 

Before calling, please write down the data from the inscrip-

tion plate (silver plate on the unit).

Alarms 

Filter timer

The control has a filter timer to guarantee that the filter is

changed and that optimal operation is established. When

the timer reaches the set value, “Chg. filter” will flash in

the display until the filters have been changed.

When the filters have been changed, the button for the

filter symbol must be held down until ”Alarm!”, “Chg. Filter”

and the exclamation mark disappears and the unit reverts

to normal operation.

Com error

This error appears when there is no communication

between the display and control. Check that the wiring is

correct on terminals 21 to 24.

21 Signal
22 Signal
23 10 Volt
24 0 Volt

Frost protection error

This error message will be displayed if a water reheater 

is fitted to the system and the temperature of the water 

reheater is too low, causing a danger of frost burst.  

The control will stop the system and open the motor- 

operated valve to keep the heater warm.
