Ruskin Co.: Zone Control System Panel

January 25, 2010


The Model Z2000 is a commercial zone control system panel that allows a single heating and cooling unit to have up to 20 individual zones. According to the manufacturer, it is ideal for light commercial applications. Each zone is controlled by its own space thermostat and motorized damper. If a majority of zones are calling for heat, the system will operate in the heating mode. The two stages of heat will be cycled to maintain the heating discharge air set point. If a majority of zones are calling for cooling, the system will operate in the cooling mode and the two stages of cooling will be cycled to maintain the cooling discharge air set point. If the number of zones calling for heating and cooling is equal, the system will operate in the cooling mode first. Each zone damper or diffuser will modulate, based on zone and discharge air temperature, to maintain the individual zone temperature set point. A barometric or electronic bypass damper will modulate to maintain the duct static pressure.
