Wiring Information and Troubleshooting
  • This page provides general guidance for wiring your LUX 24VAC mechanical thermostat. For more detailed information please refer to the instructions that came with your thermostat..
  • Please make specific note regarding LOW VOLTAGE and LINE VOLTAGE directions. Do not install LINE VOLTAGE wires to a LOW VOLTAGE control. Improper installation of a "C" wire may cause damage to your system.
  • Do no install a wire labeled "TC" from the previous thermostat to any of our controls. Installation of a "TC" wire may cause damage to your system.
  • Do NOT wire by color of the wire, wire by the LETTER designation to which the wire was attached on the previous control.
  • If there were no letter designations on your old thermostat, contact our Technical Assistance Department for assistance.
  • The instruction manual for this model can be viewed in PDF format by clicking here.

Problem Resolution
LINE VOLTAGE, 110, 120, or 240 volt wires on the previous voltage controls NEVER CONNECT LINE VOLTAGE WIRES TO A LOW VOLTAGE THERMOSTAT. Follow the wiring instructions for your control. 
Two 24 volt, LOW VOLTAGE wires on existing control for a heat only system Connect one wire to the first wired terminal, and the other to second wired terminal.
Three LOW VOLTAGE wires were connected to the previous thermostat for a heat only, forced air system where one wire operates the fan Connect the 24VAC transformer wire to the first wired terminal. Connect the heat wire and the fan wire together to the other wired terminal. NOTE: this thermostat will not allow manual control of the fan. Use a Lux Heat and Cool thermostat if this feature is desired.
Three LOW VOLTAGE wires were connected to the thermostat for a heat only, forced water system that did NOT have a clock or timer This system employs 3 wire zone valves. Please use our TX500U, TX1500U, TX9100U, TX9600TS, or TX9100E for this system.
Three LOW VOLTAGE wires were connected to the existing thermostat for a heat only, forced water system that DID have a clock or timer Tape off and do NOT install any clock or timer wire, usually labeled C or TC. Install the remaining two wires, connecting one wire to the first wired terminal, and the other to second wired terminal.
Four LOW VOLTAGE wires were connected to the existing thermostat for a heat only system, and two of the wires operate clock or timer and the other two operate the heater Tape off the two clock wires. Do not install them on any of our thermostats.  Install the remaining two wires, connecting one wire to the first wired terminal, and the other to second wired terminal.
Two LOW VOLTAGE wires were connected to the existing thermostat for heating AND cooling No current Lux controls are compatible with this system. Do not use.
