How to increase fan speed on heating mode my system was power off for 2 years and all settings gone when I on in fan speed on all 4 zone goes up by 1 speed zone 1 master 1 speed 2,3,4 1 speed each Before it was 5 master than 2 each
The zone fan speed settings are set from service/installation screen and should be set by a service person. Instructions are on the back of the controller for setting zone fan speeds
