Customer had furnace repair done by home warranty company. They bypassed Arzel control panel due to alleged failure with Arzel panel.
Upon arrival confirmed first floor thermostat is directly hooked up to furnace equipment wiring.
Also both Arzel zone dampers are open.
Advised customer for me to further diagnose issue I would need to re wire both thermostats to control panel as well as hvac equipment to control panel. Once rewriting is complete to both zones I can test zone system.
