Bosch 6 Ton Unit. I have a 3 zone system utilizing a Honeywell HZ 432 Control Panel. What I have noticed in recent days is that I am getting a Mode 2 cooling lockout(flashing light on zoning board) with a DAT in the 45-49F range. Is this normal? This happens in the evening when the unit attempts to drop my temps. Daytime setpoint is 75F(which causes the unit to run very little) and at 9pm it drops to 70F for sleeping purposes. I believe that the is a protective feature to keep the coil from freezing, but not sure that I should be having the issue. Of note, if I press the “mode” button on the HZ432 the unit will cut off and when the unit comes back on it runs with Mode 2 cooling in operation.
