I live in a rural area, where we have frequent power outages. Because of this, the existing airhandler (heatpump/separate airhandler) would "short-cycle" or go on-off-on-off (etc) in rapid succession. This action drives me up the wall hearing that sound and visualizing the commutator being "burnt", each time that it would happen. (Apparently, there was a delay timer built in to the Honeywell thermostat to protect the heatpump compressor)
Thanks to the advice of Ed Imeduc, Bloodstone, GregH, Jim-Connor and TigerDunes, of this forum, I'm having installed a Trane XL16i dual stage heatpump with a matching variable-speed airhandler.
I understand that the new heatpump is protected by a built-in "anti-restart timer".
The QUESTION...Is there any sort of anti-restart/delay timer" that can be installed to protect the new variable-speed (airhandler) blower motor, to minimize any damage done during a short-cycling event.
Many thanks to you all.

The 4TEE Air Handler has a ECM motor in it so short cycling is not the issue.
Your only concern with the Air Handler maybe a surge protection for the ECM motor and control board.

Thank you, ClassicDave, for your recommendation.
I'll run your suggestion by the contractor to install a surge protector to protect the ECM motor and the control panel OR a whole-house surge protector to cover everything.

tranquilacres,
Enjoy the XL16i, It's my Top choice for a Trane System.
2 speed compressor, 410A refrigerant.
the 4TEE is Trane's top Air Handler the ECM motor will make the
Air Handler Super Quiet in low speed. Good Stuff.

If your power goes on and off that much. Id for sure put a surge protector on the main panel. They have one that goes right in a knock out on it and ties right to the 2 hots and ground right on the mains.
