The thermostat can switch between heat mode and cool mode
either via:
Power: 24 VAC
Current consumption: 25 mA
Output signals: Depends on output configurations
Output ratings:
• the automatic changeover
• the changeover input
- Triac output: 0.5 A maximum @ 24 VAC
- Analog output (SCR connection): 0 - 10 V, 10 kW minimum
- Analog output (SSR connection): 0 - 10 V, 45 mA maximum
Setpoint range: 10°C to 35°C (50°F to 95°F)

5.5.1 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.
Note: Neither the heat mode icon ( ) nor cool mode icon (
)
Memory protection: Configuration and setpoint
Temperature control: Proportional integral adaptive (P.I.A.)
Operating temperature: 32°F to 140°F (0°C to 60°C)
Storage temperature: -4°F to 122°F (-20°C to 50°C)
Humidity limits: 0 to 95% R.H., non-condensing
Dimensions: 69 x 118 x 27 mm (2.7 x 4.6 x 1.0 in.)
appears when TH150 is placed in automatic changeover.
5.5.2 Changeover Input
The thermostat is in the default mode when the contact between ter-
minals 9 and 11 is open and switches mode when the contact is
closed. The default mode is set via the configuration menu .
Note: The changeover contact state is ignored if TH150 is config-
ured in automatic changeover or in limited cooling.
7. WARRANTY
5.6 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
(ii)
contact Aube. Aube will make the determination whether the product
should be returned, or whether a replacement product can be sent to you.
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.
Night Setback Override
To temporarily override the NSB mode, press the Over-
ride button. The NSB mode is lifted for the next 2 hours
or until the Override button is pressed again. During the
override, the normal setpoint is used and OVERRIDE is
displayed.
5.7 Error Codes
The following error codes can appear at the top of the display.
E1: The internal temperature sensor is defective
