Troubleshooting

–

Check for correct binary outputs. It should have 24 Vac. If it does not, measure the power 
input to XFMR 24 Vac input and 

 of the UC210 controller. The supply voltage should be 

between 20.4 to 27.6 Vac (24 Vac cataloged). However, voltages at either extreme may result 
in system instability.

•

Heat TRIAC(s) can be checked by purchasing a 24 Vac LED and connecting to the TRIAC output. 
If they are lit, it is calling heat output to be OPEN or CLOSED by the UC210 controller. If LED is 
not lit, replace the UC210 controller.

NOTICE: 

Equipment Damage!

The UC210 controller outputs are switched to ground. Do not jumper 24 Vac to binary output 
TRIAC(s) because damage will occur.
