Wiring Information and Troubleshooting

  • Please make specific note regarding LOW VOLTAGE and LINE VOLTAGE directions. Do not install LINE VOLTAGE wires to a LOW VOLTAGE control.
  • Do NOT wire by color of the wire, wire by the LETTER designation to which the wire was attached on the previous control.

Model LV2
   
Problem Resolution
120 VAC or 240 VAC connected to previous control DO NOT ATTACH LINE VOLTAGE WIRES TO A LOW VOLTAGE THERMOSTAT.
Although its installation is relatively simple, this thermostat is designed to switch hazardous voltage. If you are unsure of any aspect of this products application or installation consult with our technical assistance personnel, or other qualified service personnel for assistance.
Carefully follow the wiring instructions for the LV2 heating control.
Advanced Troubleshooting NOTE: Only the L1-IN/OUT pole is broken during normal temperature control.  The L2-IN/OUT pole is a pass-through and is always live unless the thermostat's set temperature knob is in the OFF position (which will break both L1 and L2 poles).
No heat when expected Verify that your thermostat's electrical connections are clean and tight.
If your house wiring at the thermostat location has aluminum wiring, the included wire nuts cannot be used and will be a potential fire hazard; these are for use with copper house wiring only.  Special CO/ALR wire connectors made spefically for aluminum must be used; please seek the assistance from a competent licensed electrician for more information.
For further assistance: Contact your HVAC service company or our Technical Assistance Line if not resolved.
