ZTWL Wiring Diagram for Aftermarket
Typical Installation
A typical installation includes two R80CJ-XX Modulating Plug&Play Dampers installed in the trunks feeding the upstairs and downstairs zones.
​
The DC3 Wireless Damper Control is installed near the equipment and wires to the equipment terminals R and C for 24VAC power. The dampers connect to the DC3 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 ZTWL 2-Zone Thermostat is installed in the downstairs zone and uses the existing thermostat wiring.
How it Works
The ZTWL monitors the downstairs temperature at its location and the upstairs temperature at the wireless sensor during heating and cooling calls.
If the upstairs and downstairs temperatures differ by 2 degrees or more, the ZTWL automatically distributes 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 ZTWL system dynamically adjusts the dampers to find the right distribution of heating and cooling to provide a uniformly comfortable home and save energy in every season.
