Where do I connect the thermostat on the CB180 or CB199?

Thermostat T-T connection, CB180-DV, CB199-DV

The thermostat (T-T) is wired to CN15 on the circuit board as shown on page 34 of the installation manual (found here: http://support.noritz.com/technical-literature.php). See image 1 below. DO NOT connect your thermostat T-T to the “Heat Demand Input” connection next to the Display Panel (Image 2).
