position 0 (open) 
3. control connectors improperly 
connected 
4. blown fuses 
5. transformer failure  

1. check the safety devices upstream from 
the humidifier and the presence of power 
2. close the switch on the panel: position I 
3. check that the connectors are properly 
inserted in the terminal block 
4. check the condition of fuses F1/F2/F3 
5. check that the voltage across the 
secondary winding of the transformer is 
24Vac  

the humidifier does not start 
operation 

1. remote ON/OFF contact open 
(relay/terminals AB - AB or 7I - 8I) 
2. the humidistat has not been 
connected correctly 
3. humidistat failure 
4. control signal not compatible 
with the type set 
5. value measured by the sensor/s 
higher than the corresponding set 
point  

1. close ON/OFF contacts (relay/terminals 
7I - 8I) 
2. check the external connection 
3. replace the humidistat 
4. set parameters A0, A2-A9 correctly 
5. check the values of the set point St and 
P7  

the humidifier fills with water 
without producing steam 

1. high steam back pressure 
2. fill valve strainer clogged 
3. mineral in the fill cup 
4. drain solenoid valve leaking  

1. check that the steam hose is not kinked 
or sagging, trapping condensate 
2. clean the fill valve strainer 
3. clean the fill cup 
4. check for 24Vac at the drain solenoid 
valve and/or drain solenoid replacement  

the thermal-magnetic overload 
switch is activated 

1. thermal-magnetic overload 
switch is under-rated 
2. over-current at the electrodes  

1. check that the thermal-magnetic 
overload switch is rated for a current of at 
least 1.5 times the rated current of the 
humidifier 
2. see description for alarm EH  

the humidifier wets the duct  

1. the distributor is not installed 
correctly (too near the top of the 
duct or the condensate return is 
blocked) 
2.system over-sized 
3.humidifier active when the fan in 
the duct is off  

1. check that the steam distributor is 
installed correctly 
2. decrease the steam production set on 
the control 
3. check the connection of the device (flow 
switch or differential pressure switch) 
slaving the humidifier to the ventilation in 
the duct (terminals 7I - 8I)  

the humidifier wets the floor 
below  

1. the humidifier drain is blocked 
2. the supply water or overflow 
circuit has leaks 
3. the condensate drain pipe does 
not bring the water back to the 
drain pan 
4. the steam hose is not properly 
fastened to the cylinder  

1. clean the drain assembly and pan 
2. check the entire water circuit 
3. check the correct position of the 
condensate drain hose in the drain pan 
4. check the fastening of the hose clamps 
on the steam outlet
