RCS 4 Zones HVAC Controller (for Standard or Heat Pump Systems)
The 4 Zone HVAC Controller series allows up to 4 standard electronic thermostats to independently control the temperature in up to 4 "zones" or areas of a building using a single heating and cooling mechanical system. Temperature control is achieved by opening or closing motorized dampers in forced air systems or valves in hydronic systems.
The 4 Zone HVAC Controller is compatible with Standard or Heat Pump HVAC systems.
For Standard HVAC systems, the controllers work with any residential style single stage heat, single stage cooling systems. (For split systems with separate power supplies, an external relay is required).
For Heat Pump HVAC systems, the controllers work with any residential style two stage heat, single stage cooling systems. The controllers can work with systems with either changeover with cooling (O) or heating (B) inputs.
The four zones are truly independent and can be in any mix of heating or cooling modes. The controllers feature auto changeover from heating to cooling modes and gives Heat calls priority.
The operation of these controllers is fully automatic and transparent to the user. Each zone thermostat provides the complete control for that zone. You can think of each zone as a separate heating/cooling system.
NOTE: Your thermostat determines the operation of the heating and cooling system and you should refer to your thermostat manual for information on how to "operate" the system.
Short Cycle Protection Delay: The controllers provide a 5-minute delay between successive compressor operations for short cycle protection. This delays one zone from calling for compressor operation shortly after another has stopped and prevents potential damage to the compressor due to rapid off-on cycling. Most thermostats also have built-in short cycle protection delays, so remember these compressor cycle delays are normal when troubleshooting the system. For testing purposes, you can reset the controller's 5 min delay by removing power from the controller.
