I bought 3 x Centralite Pearl Thermostats.
One is directly connected to HVAC without a zone controller and it is working as expected.
Two other thermostats are connected to HVAC via EWC NCM-300 and they are acting strange.
With Centrallite Pearl,
HVAC always turn on cold when I have cable connected as normal - regardless of setting I chose.
Y (Blue), G (Black), W (White) and Rc/Rh. (Red)
HVAC always turns on furnace when I intentionally swapped Y and W - regardless of setting I chose.
Y (White), G (Black), W (Blue) and Rc/Rh. (Red) .
Is Centralite Pearl compatible with Zone Controllers?
Prior to Centralite, I have Roger and White manaul T'Stat connected as follows and it is working as expected.
Y - Blue
G - Black
W - White
Rc - Red
Rh - Jumper to Rc.
Thanks,
- HVACs are Carrier Infinity and furnace uses gas.
