LockState LS-90i Internet Thermostat
[DHO-LS-90i]

$310.86

A thermostat that actually can utilize the two-stage function of our furnace. Depending on your settings... for ours if there is a greater than a two degree difference the furnace kicks in both stages to warm up quickly and make up the big difference but if it is anything lower it just kicks in the first stage and runs slower, quieter, cycles more so is more even heating and saves energy. But I'm only giving it 4 Stars because of the price.
