Rated 1 out of 5 by Benn Not user friendly We bought this home new with total energy efficient systems built in, including the thermostat, (P) X4146. It is less than 5years old and the thermostat does not function properly. It sticks at 70. no higher, no lower. I am thankful we still have heat, but with my three younger grandchildren living with us, this setting is a little too cool for much of the time at night, even out here in AZ with our dry heat. I think such a well known product name should last longer than less than 5 years? February 6, 2014
Rated 1 out of 5 by ColdinVA Short Cycles, Does not transition between scheduled and manual settings You can hear the relays inside thermostat engaging, then disengaging without turning the heat on. This happens 3-4 times and then it just stops. The scheduled heat setting does not always respond. The setting shows "Set To" 68F and the inside temperature reading shows 64F, but still no heat turns on. I manually change from scheduled heat to "Hold" and raise the temperature up to 70F and still the heat does not come on. I have to turn the system from On to Off then back On and I hear the relay engage and the heat now comes on. This happens intermittently. I have a service call placed for a technician to come out and replace the thermostat. Hopefully Lennox has seen enough of these types of problems with this unit and has a different model to replace it with. January 7, 2014
Rated 1 out of 5 by Kennedy Cycles too often This thermostat cycles my heat on about every 10 mins and the furnace runs for about 5 mins and shuts off. The inside temperature on the unit doesn't even fluctuate, it stays at the set point. It seems to have a half degree differential even thought its set at 3 degrees. I've tried increasing the differential and also the cycles per hour and the thermostat still does these short cycles. November 30, 2013

Rated 2 out of 5 by OoMoment Industrial Relay Noise from Thermostat -Unacceptable There are six relays in this thermostat... all of them make a loud click when activated. The unit is mounted in the hallway adjacent to the master suite...CLICK CLICK CLICK all night long... if you own one of these you'll become a person who sleeps with a pillow over your ears all night....;-( March 21, 2013
