. Introduction  
The TH150 Series electronic thermostat is designed for low-voltage  
pressure-dependent variable air volume (VAV) applications. It  
comes in four different models:  
TH150-1A  
• TH150-1F  
Configuration and status display  
TH150-1A2T  
• TH150-1F2T  
Depending on the model, the TH150 thermostat can have up to  
three outputs connected to the following control devices:  
Heating mode  
actuators  
thermal valves (N.O. and N.C.)  
solenoid valves  
solid-state relays (SSRs)  
silicon-controlled rectifiers (SCRs)  
mechanical relays

2.2 Terminal Designations  
The designations of the terminals vary according to the particular  
model of thermostat. Refer to the following table for the description  
of each terminal.  
n Remove the thermostat from its base by unscrewing the cap-  
tive screw and tilting the bottom of the thermostat up. The  
screw cannot be completely removed.

.3.3 Opening time (1F and 1F2T models only)  
To use the outdoor air for cooling whenever possible.  
The AC146-410 temperature sensor is used to measure  
the outdoor air temperature. The internal temperature  
sensor measures the room temperature which is then  
compared with the setpoint. If the room temperature is  
lower than the setpoint, the air intake damper remains  
closed. If the room temperature is higher than the  
setpoint, the latter is then compared with the outdoor  
temperature. If the fresh air temperature is lower than  
the setpoint by more than 3°C (5.4°F), the damper  
opens to allow cool air in.  
The damper opening time can be set between 80 and 160 seconds.  
4.4 Output 2 (models TH150-1A2T and TH150-1F2T)  
Limited

Output 2 controls heating only, regardless of the thermostat’s mode.  
When the thermostat is in heat mode, Output 2 is activated as soon  
as Output 1 reaches its full capacity. When the thermostat is in cool  
mode, Output 2 is activated when the measured temperature drops  
below the setpoint.  
5
4.3 Output 1  
Output 1 is used to control a damper. It controls heating when the  
thermostat is in heat mode or cooling when the thermostat is in cool  
mode.

corresponding settings in the configuration menu.

. Operation  
5.1 Power-Up  
Upon power-up, the thermostat undergoes a series of test before  
displaying the actual temperature.  
Note: On the TH150-1F and TH150-1F2T models, at power-up, the  
message OPEN appears at the top of the screen during the calibra-  
tion of the damper opening. This can last up to 3 minutes.  
5
.2 Backlight  
To turn the backlight on, press any button. The display will illuminate  
for 12 seconds.  
When setting 5 is selected, Output 3 controls heating or cooling  
depending on whether the default mode has been set to heat or  
cool respectively (see section 4.3.1). For example, if the default  
mode has been set to heat mode, the contact remains opened when  
the thermostat is in cool mode. When the thermostat is in heat  
mode, the contact closes when Output 1 reaches a percentage of its  
capacity, set via the configuration menu.  
5.3 Temperature Display and Setting  
The thermostat usually displays the actual temperature. To view the  
setpoint, press once on one of the

buttons. The setpoint  
Note: The temperature setpoint is automatically increased or  
decreased by 1°C (2°F) when the controller switches to heating  
mode or to cooling mode respectively. For example, if the setpoint is  
at 25°C (77°F) in heating mode, it will become 26°C (79°F) in cool-  
ing mode and will return to 25°C (77°F) when the controller is back  
in heating mode.  
5.4 Output Display  
The bar graph represents the voltage for an analog out-  
put or the duty cycle for a triac output. The bar graph  
usually shows Output 1 power (% of damper opening).  
To view Output 2 or 3, press Override for 2 seconds to  
enter the diagnostic mode. Press Override momentarily  
to switch between the three output graphs. To exit the  
diagnostic mode, press Override for 2 seconds or wait  
for 1 minute for the mode to exit automatically.

.5.1 Automatic changeover  
In automatic changeover, the thermostat detects when the system  
switches between heat mode and cool mode by comparing the air  
supply temperature with the ambient temperature. If the thermostat  
is in heat mode, it switches to cool mode when the air supply is  
cooler than ambient by 5°C (9°F) or more. If it is in cool mode, it  
switches to heat mode when the air supply is warmer than ambient  
by 5°C (9°F) or more.

.6 Night Setback  
Aube warrants this product, excluding battery, to be free from defects in the work-  
manship or materials, under normal use and service, for a period of three (3)  
years from the date of purchase by the consumer. If at any time during the war-  
ranty period the product is determined to be defective or malfunctions, Aube shall  
repair or replace it (at Aube's option).  
The Night Setback (NSB) mode is activated when the  
contact between terminals 9 and 12 is closed. When  
TH150 is in the NSB mode, indicated by the ECONO  
display, the temperature is lowered or raised by the set  
NSB value depending whether the thermostat is in heat  
mode or cool mode respectively. The NSB value is set via the con-  
figuration menu.  
If the product is defective,  
(
(
i)  
return it, with a bill of sale or other dated proof of purchase, to the place  
from which you purchased it, or  
contact Aube. Aube will make the determination whether the product  
should be returned, or whether a replacement product can be sent to you.  
ii)  
Night Setback Override  
This warranty does not cover removal or reinstallation costs. This warranty shall  
not apply if it is shown by Aube that the defect or malfunction was caused by  
damage which occurred while the product was in the possession of a consumer.  
Aube's sole responsibility shall be to repair or replace the product within the terms  
stated above. AUBE SHALL NOT BE LIABLE FOR ANY LOSS OR DAMAGE OF  
ANY KIND, INCLUDING ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES  
RESULTING, DIRECTLY OR INDIRECTLY, FROM ANY BREACH OF ANY WAR-  
RANTY, EXPRESS OR IMPLIED, OR ANY OTHER FAILURE OF THIS PROD-  
UCT. Some provinces, states or regions do not allow the exclusion or limitation of  
incidental or consequential damages, so this limitation may not apply to you.  
THIS WARRANTY IS THE ONLY EXPRESS WARRANTY AUBE MAKES ON  
THIS PRODUCT. THE DURATION OF ANY IMPLIED WARRANTIES, INCLUD-  
ING THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PAR-  
TICULAR PURPOSE, IS HEREBY LIMITED TO THE THREE-YEAR DURATION  
OF THIS WARRANTY. Some provinces, states or regions do not allow limitations  
on how long an implied warranty lasts, so the above limitation may not apply to  
you.

ride button. The NSB mode is lifted for the next 2 hours
