1990s LENNOX 21J7101 Multi Stage Heat Pump Replacement Thermostat UNUSED IN BOX:
$69.99
For sale is a Lennox thermostat. This thermostat is quite old, from 1992, and is model 21J7101. The box/manual indicates that it is a multi stage heat pump thermostat with manual changeover, with 2 stage heat and 1 stage cooling. The unit still has the original padding and card inside, and has not been mounted. It comes with the box, mounting screws, and data sheet. I know it\'s an old unit, but it\'s technically a brand new replacement if you have an older system and use a model like this, and would like to keep the same style thermostat.
