Installation and User Guide

Programmable Thermostats

o Installation

Note: The installation must be performed by an electrician.

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.

oIdentify and label each wire (with the corresponding letter on the wire terminal) and remove them from the terminals.

p If necessary, strip the end of each wire (maximum of 6 mm).

2.2 Installing the New Baseplate

Choose a location approximately 1.5 m 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.

n Remove the thermostat faceplate.

oLoosen the locking screw in order to separate the thermostat from its baseplate (the screw cannot be completely removed).

p Gently tilt the thermostat upwards.

qPass the wires through the opening of the baseplate and secure the baseplate to the wall using the appropriate screws.

NOTE:

No polarity to observe.

2.5 Unoccupied Mode Input (TH148ELE-P only)

TH148ELE-P has an input that can be used to lower the temperature when the house is unoccupied. You can connect an Aube’s CT240 telephone controller (optional) or another remote control system.

When the thermostat receives a 12-VDC signal, it switches to the unoccupied mode where the setpoint programmed for that mode is used (see section 5). When the signal is removed, the thermostat returns to the previous mode.

2.5.1 Connecting to CT240

Connect TH148ELE-P terminals UN and UN to CT240 terminals A and C (no polarity to observe).

2.5.2 Connecting to a Home Automation System

Connect TH148ELE-P terminals UN and UN to a 12-VDC circuit as shown (no polarity to observe).

2.6 Installing the Batteries

:

n Gently pull out the battery cover.

o Install the batteries as shown. Observe the polarity.

p Re-install the battery cover. You will hear a clicking sound.

After the batteries are installed, the thermostat performs a series of tests for approximately 5 seconds.

Afterwards, the thermostat displays the temperature. It is possible that the displayed temperature is higher than the ambient temperature if you are holding the thermostat in your hands. Once installed on the wall, the thermostat will display the ambient temperature. The time and day settings flash to indicate that they must be set (see section 4.1).

2.7Completing the Installation

nOnce the baseplate and the batteries are installed, mount the thermostat on the baseplate.

oSecure the thermostat using the locking screw and install the faceplate.

pApply power back to the system.

pBasic Functions

3.1 Backlight

The display illuminates for 12 seconds when the backlight button or any other button is pressed.

3.2 Displaying the Temperature

The actual (measured) temperature is normally displayed. To view the setpoint temperature, press once on either of the buttons. The setpoint, along with the icon, will be displayed for the next 5 seconds.

3.3 Setting the Temperature

Press one of the buttons until the desired temperature is displayed.

3.4 Comfort and Economy Temperatures

The thermostat has 2 preset temperature buttons:

•Comfort temperature

•Economy temperature

To set the thermostat at the Comfort or Economy temperature, press the corresponding preset button. The corresponding symbol will be displayed.

The following table shows the use and the factory setting of each preset button.

Button	Intended use	Default setting
	Comfort (when the occupant is awake and at home)	21°C
	Economy (when the occupant is absent or asleep)	17°C

To modify the Comfort or Economy temperature:

n Set the desired temperature using the buttons.

oPress and hold the appropriate preset button until the corresponding symbol is displayed.
