WIRING INFORMATION |
| Model |
TX9000TS |
| Description |
|
| ALL |
- Never connect a low voltage thermostat to line voltage.
|
| |
|
| Two wires control a heat only system. |
- Connect one wire to W and the other to RH.
|
| |
|
| Two wires control a cool only system. |
- Connect one wire to RC and the other to Y.
|
| |
|
Three wires for forced air heat only system, where the previous thermostat did not have
a clock or timer. |
- The previous RH or RC wire is the 24-volt transformer wire. Connect it to RH. Leave jumper connecting RH to RC. Connect the forced air heat system to W, and the fan wire to G.
|
| |
|
| Three wires for a heat only, forced water system that did NOT have a clock or timer. |
- This system employ 3 wire zone valves. Currently no Lux controls are compatible with this system.
|
| |
|
| Three wires control a heat only, forced water system that DID have a clock or timer. |
- Tape off and do NOT install any clock or timer wire. Often they are labeled C or TC. Install the remaining two wires, one to RH and the other to W.
|
| |
|
Four wires control a heat only system, and
two of the wires operate clock or timer. The other two wires operate the heater. |
- Tape off and do NOT install any clock or timer wire. Often they are labeled C or TC. Install the remaining two wires, one to RH and the other to W. The jumper connecting RH to RC may remain or be removed.
|
| |
|
| Two wires control heating AND cooling. |
- Currently no Lux controls are compatible with this system.
|
| |
|
Three wires control heating and cooling.
One wire operates heat, one operates
cooling and the third provides 24 VAC. |
- Connect the 24-volt power wire to RH. Install a jumper connecting RH to RC. This jumper is usually pre-wired. connect the heat wire to W, and the cooling wire to Y.
|
| |
|
Three wires control a cooling only system.
One wire operates the compressor, one operates the fan and the third provides
24 VAC. |
- Connect the 24-volt power wire to RC. Connect the cooling wire to Y and the fan wire to G.
|
| |
|
| Four wires control a heating and cooling, electric, gas or oil, forced air system that is NOT a heat pump. |
- Connect the 24 VAC transformer wire to RH or RC. Install a jumper connecting RH to RC This jumper is often prewired. Connect the heat wire to W, the cooling wire to Y. and the fan wire to G.
|
| |
|
| Four wires control a Single Stage Heat Pump. They were labeled: G, Y, R or RH or RC, With either B or was used. |
- Do not connect wires to both B and O. Connect the reversing valve wire to B or O, just as the previous thermostat. Install a jumper wire from RH to RC. Connect 24 VAC wire to RH too. Install a second jumper wire from W to Y. Connect compressor wire to Y and the fan wire to G.
|
| |
|
| More than 4 wires are connected to the old thermostat. |
