Typical Installation
A typical installation includes two round R80CJ or rectangular RT80CJ Modulating Plug&Play Dampers installed in the trunks feeding the upstairs and downstairs zones. Additional dampers can be installed to define the zones if needed.
The DC3M Wireless Damper Control is installed near the equipment and wires to gas/electric equipment terminals W and Y or heat pump equipment terminals Y, O or B, and E to monitor the equipment for heating and cooling calls. The DC3M is powered by a plugin 24VAC adapter. The dampers connect to the DC3M using the included plug&play cables.
The TSWL Wireless Temperature Sensor is installed in the upstairs zone, is battery powered and requires no wiring.
The ZCDWL Wireless 2-Zone Control is installed in the downstairs zone, is battery powered and requires no wiring. The ZCDWL is compatible with Smart, OEM or simple 24VAC thermostats. Alternately, the ZCDWL can be installed in the upstairs zone and the sensor installed in the downstairs zone.
How It Works
While the thermostat controls the HVAC equipment and the temperature in the home, the ZCDWL monitors the equipment for heating and cooling calls and monitors the downstairs temperatures at its location and the upstairs temperature at the sensor.
If the upstairs and downstairs temperatures differ by 2 degrees or more, the ZCDWL automatically distributes 2% more heating or cooling to the zone that needs it every 2 minutes.
To distribute more heating or cooling upstairs, the upstairs damper fully opens and the downstairs damper partially closes, forcing more heating or cooling to the upstairs zone. To distribute more heating or cooling downstairs, the downstairs damper fully opens and the upstairs damper partially closes, forcing more heating or cooling to the downstairs zone.
The ZCDWL system dynamically adjusts the dampers to find the right distribution of heating and cooling
to provide a balanced, uniformly comfortable home and save energy in every season.
