Selects how the auxiliary heat is
used.
Default:
comfort
(economy) –
in the heating mode: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized to satisfy
the setpoint only when the temperature has dropped 2F°/1C° below
the heating setpoint.
Note:
Selecting economy in the heating mode adds a deadband
between the heat pump and auxiliary heat. The actual
temperature maintained is lower than the true heating
setpoint to maximize the heat pump operation. When the
outdoor air temperature drops below the low balance point,
the deadband is eliminated.
(economy) –
in the emergency heat mode: The setpoint that is
maintained is the heating setpoint.
(comfort) –
in the heating mode: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized to satisfy
the setpoint.
Re valve
Governs the reversing valve
operation.
Default:
O
(B):
Energizes the valve in heating operation (valve is normally cool)
(O):
Energizes the valve in cooling operation (valve is normally heat)
Comp/aux
Sets the mode of interaction
between the heat pump and the
auxiliary heat.
Default:
off
(on) –
in the heating mode only: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized and the
heat pump is shut off. This typically applies when the air handler
heat pump coil is installed after the auxiliary heat. There is a
2-minute delay to restart the heat pump after the auxiliary heat is
shut down.
(off) –
in the heating mode only: If the heat pump is not able to
satisfy the heating setpoint, the auxiliary heat is energized at the
same time as the heat pump stage. This typically applies when the
air handler heat pump coil is installed before the auxiliary heat (all
electric systems).

Setting DI1 or DI2 to RemNSB disables schedules and stops the Schedule menu display. Any other setting enables
schedules and the Schedule menu. (TEC2262-3 only)
2.
When adjusting the numeric value, press the
UP
or
DOWN
arrow key to change the value by single increments; press and
hold the
UP
or
DOWN
arrow key to change the numeric value in increments of ten.
3.
When adjusting the temperature, press the
UP
or
DOWN
arrow key to change the value in 0.5F°/0.5C° increments; press
and hold the
UP
or
DOWN
arrow key to change the value in 5.0F°/5.0C° increments.
4.
When the outdoor air sensor is not connected or it has a short, the thermostat bypasses heating lockout, cooling lockout,
high balance point, and low balance point. Emergency mode bypasses heating lockout and permits auxiliary heating
whenever a heating demand occurs.
