Model HP2110
   
Problem Resolution
ALL
  1. Never connect a low voltage thermostat to line voltage.
   
Two wires control a heat only system.
  1. Connect one wire to W and the other to RH.
 
Two wires control a cool only system.
  1. 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.
  1. 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.
  1. 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.
  1. 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.
  1. 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.
  1. 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.
  1. 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.
  1. 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.
  1. 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.
  1. 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.
