I have not had to use my bedroom, zone 2, unit much but it still cycles more than the living room A/C. Check to make sure the a/c vent air is not blowing right at the little thermostat sensor on the ceiling, this could cause the short cycle on zone 2. Before the new thermostat my zone 1 a/c would cycle about every 4 minutes, as much as13 times per hour. There is no way to adjust the temperature difference in A/C mode. It acted like it was reading a 1/4 degree difference when it should have been 1 or 2 degrees difference as to not run short cycles. These are very cheap thermostats. Wish a regular Honeywell that you can get anywhere would work with these dual air systems.
