Pins
•Click the gear icon at the bottom left corner of the main
screen.
•Scroll down to the Installation Settings.
•For our thermostat with 5 wires we will select Heat Pump
1 stage (if applicable) with default temperature tolerance.
•Once finished the connector pins will be shown.Take a
picture of this screen.
•Now disengage power and connect remaining wires using
the picture from the previous step.
•If your heating and cooling system is a heat pump and it
blows warm air when your Karandash F-22 thermostat is
in cooling mode, your heat pump system uses a
changeover valve controlled by the O/B wire. Simply invert
the O/B values in the installation settings.

•A digital thermostat can do a few things that a regular
mechanical thermostat cannot. One of the most useful
features of a digital thermostat is programmable settings. In
the winter, you can program it to automatically turn up the
heat for an hour or two in the morning while you get
ready for work, turn down the heat until you get home,
turn up the heat in the evening and then turn down the
heat while you!sleep.This is a great money-saving feature
because you can simply turn down the heat when it isn't
needed.
•If the scheduling feature is used, make sure each empty
row is populated with time and temperature.
