PB112

Installation Instructions

For models: 120S / 240S / 240D

nParts

nOne (1) power base

oTwo (2) screws

pFour (4) solderless connectors for copper wires

NOTE: Special CO/ALR solderless connectors must be used for connecting aluminum conductors.

Option

qOne (1) AC112-01 floor sensor (ordered separately; required for floor heating applications only)

oGuidelines

Turn off power to the heating system at the main electrical panel to avoid electrical shock. The installation should be carried out by an elec- trician.

sIf necessary, set the configuration switches on the control module (refer to the control module user guide).

tInstall the control module onto the base. u Apply power to heating system.

Power

Load

NOTE: This power base must be used with thermostat operating on 15-minutecycles.

High voltage thermostats must be installed onto an electrical box.

The following guidelines are not necessary for floor heating applica- tions:

For a new installation, choose a location about 1.5 m (5 ft) above the floor and on an inside wall.

The thermostat must be installed on an inside wall facing the heating system.

Avoid locations where there are air drafts (top of staircase, air outlet), dead air spots (behind a door), direct sunlight or concealed chimneys or stove pipes.

pProcedure

nConnect the power base wires to the power supply and load using sold- erless connectors for copper wires (figure 1).

oFor floor heating applications, insert the floor sensor wires through one of the two holes below the terminals (figure 2) and connect the wires to terminals 3 and 4 (no polarity).

NOTE: The wires must run alongside the terminals and not go over them. The wire must not cross any heating wires nor be placed directly on a heating wire or adjacent to it. For best performance, the sensor probe should be centered between the wires in the mat.

WARNING: This power base does not have a built-in ground protection device. Therefore, for floor heating applications, you must install a sepa- rate ground protection device at the main electrical panel. Contact your Aube authorized representative if you need a thermostat with built-in ground protection device.

pIf you wish to use a remote controller such as the CT240 or CT241,

insert the cable (use 18 to 22 gauge flexible wires) into one of the two holes available below the terminal board and connect to terminals 1 and 2 of the base (figure 2).

qPush the excess length of the high-voltage wires back into the electrical box.

rSecure the power base to the electrical box using the provided screws.
