INTRODUCTION
The CarrierrCôrtthermostat is a wall--mounted, low--voltage
thermostat which maintains room temperature by controlling the
operation of a heating and/or air conditioning system, both heat pump
and air conditioner models. Your Côr thermostat has a color touch
screen and interface similar to that used in smart phones. A variety of
features are provided including remote access through web and mobile
apps, separate heating and cooling setpoints, auto changeover, keypad
lockout, backlighting, and built--in installer test. Programing features
allow each day to be independently programmed in half an hour
increments with four preset periods (Home, Away, Sleep, Wake) and
up to six additional custom profile periods. For operational details,
consult the online Owner’s Manual for the specifics at
www.Carrier.com/homecomfort.
INSTALLATION CONSIDERATIONS
Power
This thermostat is powered by 24VAC through the C terminal and thus
most applications require a minimum of 5 thermostat wires. Provision
is made for separate heating and cooling transformers via separable Rc
and Rh terminals which are internally jumpered unless both Rc and Rh
are utilized. Internal jumper is controlled by a relay after the thermostat
senses whether Rc and/or Rh wires are connected to the terminal
block.
