I recently purchaced a Condo that contains the following:

Lennox 13HPD-36 Heat Pump
Lennox CB26UH-36 Air Handler
Lennox X4146 T-Stat

Cooling works just fine, but when you call heat nothing happens. I temporarily fixed the problem by swapping the T-stat with a different one but would like to get the Lennox programible one working.

My guess is it was never set up for Heat Pump operation. the only manuals I can find online are user manuals that refer to a "Installer manual" that is nowhere to be found.

Could someone out there that has an installer manual please tell me how to access the install menu and set the T-stat to Heat Pump mode?

Here you go.

I am not an employee of CozyParts, I generously donate my time. The services here are free, with honest intention to assist, however, this site is not free to maintain. Please make the effort if you need a part or tool to purchase from CozyParts.com. This will ensure this wonderful forum remains for years to come!! As a Lennox Technician I feel basic repairs and maintenance can be performed by the homeowner. But I highly suggest that periodic maintenance should be made by a certified licensed technician. You should contact your local Lennox technician for any repairs or issues that are outside your comfort zone. Property damage, personal injury, and death can occur from improperly repaired or maintained systems. Replacing a part doesn't always resolve the issue that caused the part to fail!
