Description

The Comfort System Z-2000 (formerly the Z-1600) is the latest generation of commercial zone control systems that allows a single HVAC unit to have up to 20 individual zones. Each zone is controlled by its own space thermostat and a modulating or two-position zone damper. When a majority of zones are calling for cooling, the system operates in the cooling mode. The Z-2000 controls up to two stages of cooling to maintain a cooling discharge air setpoint. If a majority of zones are calling for heating, the system changes from the cooling mode to the heating mode. The Z-2000 then controls up to two stages of heating to maintain a heating discharge air setpoint. When the number of heating and cooling requests are equal, the system satisfies the cooling requests first.

 

Comfort System zone dampers are available in round and rectangular, as well as VAV diffusers. All three types are controlled by a P+I modulating Z-2000-T thermostat. Each zone thermostat wires to its own zone damper which wires back to the Z-2000 panel. The zone damper is driven by a floating point actuator and has a duct temperature sensor. The thermostat controls the zone damper to maintain room temperature in both cooling and heating modes. When the zone temperature falls below the heating setpoint, the zone damper sends a signal to the Z-2000 control panel requesting heat. When the zone temperature rises above the cooling setpoint, the zone damper sends a signal to the Z-2000 panel requesting cooling. These signals are used to determine the mode (heating or cooling) of the HVAC unit as described above. The zone damper heating output can also be used to control auxiliary baseboard, duct, or ceiling radiation heat.

A bypass damper is installed between the supply and return air duct to maintain the proper system static pressure. Bypass dampers are available in both electronic and barometric type. Electronic bypass dampers are recommended for systems with cooling capacities exceeding 7.5 tons. Barometric bypass dampers are recommended for systems with cooling capacities of 7.5 tons and lower.
