The pump and boiler n delay and the pump ff delay are fi ed at 3 minutes in the software and at 0 in the terminal. The n delay starts when any zone is turned on and stays on. The ff delay starts when the last zone is turned off.

The boiler ff delay is controlled by a jumper and can be either 0 or 1 minutes. To select the desired delay, place the jumper in the position corresponding to the desired delay time.
