Recently installed an ewc zone system on daikin modulating furnace and modulating inverter heat pump. Two zone boards to control 4 zones. System seems to operate normally when using heat pump but as soon as Daikin One thermostat is put into emergency heat mode (furnace) all dampers will close and the blower ramps up to full speed. Also if you lightly wipe the clear cover on the zone controller the board will cycle off and on.
