Symptom

Probable Causes

Solutions

The controller displays 

Idle

 with a 

Unit 

Status of Cooling Unavailable due to 
OA Temp

 despite being above cooling 

setpoint, or with a status of 

Heating 

Unavailable due to OA Temp

 despite 

being below the setpoint. 

The outdoor air temperature is too 
warm for heating or too cold for 
cooling.

1. If Cooling and Heating Lockout 

Setpoints are inadequate, adjust 
the setpoints.

2. Wait for the outdoor conditions to 

be favorable for heating or cooling.

The controller displays 

Idle

 with a 

Unit 

Status of Cooling Unavailable due to 
Control Mode

 despite being above 

cooling setpoint, or with a status of 

Heating Unavailable due to Control 
Mode

 despite being below the 

setpoint. 

The Control Mode is set to Cooling 
Mode, but the controller is requesting 
heating.

Change the Control Mode to Auto or 
Heating.

The Control Mode is set to Heating 
Mode, but the controller is requesting 
cooling.

Change the Control Mode to Auto or 
Cooling.

The controller displays 

Idle

 with a 

Unit 

Status of Cooling Unavailable

 

despite being above cooling setpoint, 
or with a status of 

Heating 

Unavailable

 despite being below the 

setpoint.

The Number of Compressors set to Not 
Used and the controller is requesting 
cooling, or Number of Heating Stages 
is set to Not Used.

Adjust the number of compressors and 
number of heating stages to match the 
configuration of the unit.

The heat pump does not sequence 
properly. 

The heat pump requires traditional 
wiring (Y1, Y2, W1, W2, and G) and 
handles the reversing valve internally, 
but Heat Pump Supported is set to Yes.

Consult the equipment documentation 
to verify wiring configuration, then set 
Heat Pump Supported to No.

The heat pump requires thermostat to 
control the reversing valve (Y1, Y2, 
O/B, and G) but the Heat Pump 
Supported is set to No.

Consult the equipment documentation 
to verify wiring configuration, then set 
Heat Pump Supported to Yes.

The heat pump heats when it should be 
cooling, and cools when it should heat. 

Reversing Valve polarity is incorrectly 
set.

Consult the equipment documentation 
to verify reversing valve polarity, then 
adjust the Reversing Valve Polarity 
menu option accordingly.

The staged equipment shuts off above 
the cooling setpoint or below the 
heating setpoint when the PID is 
running on the TEC. If the unit is in On/
Off Control mode, this does not apply.

The PID control algorithm minimizes 
overshoot and energy usage for the 
particular equipment and zone, and 
may cycle the equipment prior to 
reaching setpoint.

Expected behavior.

The staged equipment cycles too 
rapidly or too slowly when the PID is 
running on the TEC.

The control band around the setpoint is 
determined by the minimum on/off 
times and is set incorrectly for the 
equipment, zone, or user preference. 
There is a tradeoff between reduced 
control band size and increased 
energy usage and equipment wear 
from increased cycling.

1. Verify that equipment minimum on/

off times are set correctly.

2. If the default deadband around the 

setpoint does not provide the 
desired temperature control, set 
Temp Control Setup to Deadband 
Override and set the Deadband 
parameter to the desired value.

The controller provides an error when 
trying to upgrade firmware. 

The firmware on the USB drive is 
below the minimum required version.
Error code 1025.

Please use firmware version 3.0.2.xxxx 
or higher.
A reboot is required to clear the 
Firmware Mismatch fault that occurs.

The zone space temperature increases 
or decreases too much when the unit is 
active in unoccupied mode.

The heating and cooling equipment are 
too big for the unoccupied space.

Decrease the Unoccupied Off Delay 
parameter from 10 minutes to a more 
appropriate time for the equipment 
configuration.

The TEC3000 zone temperature does 
not change fast enough compared to 
the measured zone temperature from a 
verification device (a calibrated 
sensor).

The TEC3000 is configured by default 
for larger spaces with normal-sized 
equipment when a proportional device 
is active.
