Aube Technologies TH149 User Manual

Electronic Thermostat

for Heat Pump and HVAC Systems

Installation and User Guide

The TH149 thermostat is used for the following systems:

The thermostat incorporates the following functions:

Introduction

• Heat pump (1H1C and 2H1C)

• HVAC (1H1C)

• System mode selection: heat, cool, auxiliary heat and off

• Fan mode selection: automatic or on (continuous)

• Emergency heat and fault LEDs

• Activation indicators (heat, cool, and auxiliary heat)

• Temperature display in °C or °F

• Backlit display

• Programmable heating and cooling cycle lengths

• Keypad lock

n Loosen the locking screw (the screw cannot be com-

pletely removed).

o Detach the front module from the back plate by pulling

the bottom part.

p If necessary, bore the mounting holes

and insert anchors.

q Pass the wires through the opening of

the back plate and fix the plate to the wall using the screws provided.

2.3 Connecting the Thermostat

The connection of the new thermostat should be similar to that of the old thermostat; however, it can vary depending on the installation.

2.1 Removing the Old Thermostat

IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, CUT POWER TO THE HEATING SYSTEM.

n Remove the old thermostat to access the wires. o Identify and label each wire (with the corresponding letter on the old ther-

mostat terminals) and remove them from the terminals.

p If necessary, strip the end of each wire (maximum of 6 mm). q If necessary, wrap the wires around a pencil to pre-

vent them from falling into the wall cavity.

r If the opening in the wall is too big, insulate it using

a non-flammable material to avoid air draughts behind the thermostat.

2.2 Installing the Back Plate

Note: 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.) or dead air spots (behind doors). Do not install the thermostat on a wall concealing air ducts nor expose it to direct sunlight.

2.5 Completing the Installation

n Reinstall the front module onto the back plate and tighten the locking

screw.

o Place the system mode selector switch to OFF.

Note: Leave the switch to OFF until you have verified that the thermostat is

properly configured (see section 3).

p Apply power back to the system. q Ensure that the thermostat is configured according to your system type

(see section 3).

When either the heating or the cooling parameter is displayed, use the mode selector switch to toggle between the two parameters.

The corresponding cycle lengths are: 2 = 30 min., 3 = 20 min., 4 = 15 min., 5 = 12 min., 6 = 10 min.

This parameter appears only if you select 1H1C for the system type.

n To access the configuration menu, press and hold both temperature

adjustment buttons for more than 3 seconds.

o To go to the next parameter, once in the menu, press both temperature

adjustment buttons for more than 2 seconds.

p To modify the displayed parameter, press one of the temperature adjust-

ment buttons.

q You will exit the configuration menu at the end of the menu.

Note: The settings are not erased during a power outage.

4.1 System Mode

Use the system mode selector switch to place the system in heat mode, cool mode, emergency heat (E.H.) mode, or off.

Note: Emergency heat mode is not available on 1H1C systems.

For these systems, placing the selector on E.H. is the same as placing it on Off.

Auxiliary Heat

Only 2H1C systems are equipped with auxiliary heat. The auxiliary heat is used in the following conditions:

• When the setpoint is not attained after a 15-minute delay following the

• When the thermostat is placed in emergency heating (E.H.). In this mode,

4.2 Fan Mode

Use the fan mode selector switch to place the fan in automatic mode (AUTO) or continuous mode (ON).

Note: This switch is not functional if the fan is not connected to

the thermostat.

4.3 Viewing and Setting the Temperature

The actual temperature is normally displayed. To view the setpoint, press once on one of the temperature adjustment buttons. The setpoint is displayed

for 5 seconds and is indicated by the icon display. To change the setpoint, press the appropriate temperature adjustment button during the setpoint display.

4.4 Backlight

The display illuminates for 12 seconds when either of the temperature adjustment buttons is pressed.

only the auxiliary heat is used.

AUTO The fan operates only when heating or cooling is activated.

ON The fan operates continuously.

4.5 Setpoint Lock

A switch on the back of the front module can be used to lock the setpoint.

n Remove the front module from the

back plate to access the switch.

o Place the switch (S1) to the I posi-

tion.

p Reinstall the front module.
