Function
This panel can provide mixing, distribution, and zoning for a wide variety of hydronic heating applications.
The eff ectiveness of the system is dependant on the system being designed and installed correctly. Proper consideration
of factors such as BTU loads, outdoor design temperature, indoor design temperature, room set-point temperature(s),
diff erential fl uid temperatures, head loss, fl ow rates, and transfer capacities of the heat emitters is critical.
Once these factors have been considered and the system requirements determined, these can then be evaluated and
compared to the zone control panel capabilities (refer to pages 5-9).
Note:
This panel does not regulate or monitor the operating safety limit temperatures of the fl uid leaving the heat source.
