Built-in simplicity since vapor is switched instead of liquid, therefore no condensate is produced which means fewer valves are required.
Electronically controlled valves, and a fully insulated valve housing minimizes noise.
Increased reliability since fine mesh strainers protect the valves.
Low-noise valve operation means quieter operation and no need to place the changeover box in a remote location.
Reliable performance as valves work according to the demand of each zone.
Easy service access to valves with a simplified design.
