INTRODUCTION
The BryantrHousewisetthermostat 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 Housewise 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.Bryant.com.
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.
