Comf/eco

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).

1.

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.
