Aube Technologies TH147-P Installation And User Manual

TH147-P

                                              1/12

The TH147-P programmable thermostat can be used to control: 

• a gas, fuel oil or electric furnace - 2 or 3 wires

• a central air conditioner - 2 or 3 wires

• a hot water system with or without pump - 2 wires

• a millivolt system - 2 wires

• a central heating and cooling system - 4 or 5 wires

Attention

: This thermostat is not compatible with heat pumps or

multi-stage systems.

Note

: The installation must be performed by an electrician or a quali-

fied installer.

2.1

Removing the Old Thermostat

IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT

POWER TO THE HEATING/COOLING SYSTEM. 

Remove the old thermostat to access the wires.

Attention

: If the old thermostat was mounted onto an electrical box,

it might have been powered by 120/240 volts. In this case, the

TH147-P thermostat cannot be used.

Identify and label each wire (with the corresponding letter on the 

wire terminal) and remove them from the terminals. 

If necessary, strip the end of each wire 

(maximum of 6 mm).

Wrap the wires around a pencil to prevent 

them from falling into the wall.

If the hole in the wall is too big, insulate it 

using a non-flammable material in order to 

avoid air draughts behind the thermostat.

2.2

Installing the New Baseplate

For a new installation, choose a location approximately 1.5 m (5

feet) above the floor and on an inside wall. Avoid draughty areas

(top of staircase, air outlet, etc), dead air spots (behind doors),

direct sunlight or areas near concealed pipes or chimneys.

Remove the thermostat faceplate.

Loosen the locking screw in order to separate the thermostat 

from its baseplate (the screw cannot be completely removed).

Gently tilt the thermostat upwards.

Mark and bore the appropriate mounting holes (or use the 

existing holes). Insert the plastic anchors.

Pass the wires through the opening of the baseplate and fix the 

baseplate to the wall using the screws provided.

2.3

Connecting the Thermostat

Refer to the following table for matching the wire labels with the

thermostat terminals.

Note: Do not connect wires identified as C, X or B. Wrap the bare

end of these wires with electrical tape.

Loosen the screws of the 

terminal block and insert the 

wires in the respective 

terminals. 

Tighten the screws.

Important: The red jumper wire

between Rh and Rc terminals must

be removed in a 5-wire installation.
