PB112 Installation Instructions

Parts

1. One (1) power base
2. Two (2) screws
3. Four (4) solderless connectors for copper wires
   NOTE: Special CO/ALR solderless connectors must be used for connecting aluminum conductors.
   Option
4. One (1) AC112-01 floor sensor (ordered separately; required for floor heating applications only)

Guidelines

Turn off power to the heating system at the main electrical panel to avoid electrical shock. The installation should be carried out by an electrician.
NOTE: This power base must be used with thermostat operating on 15-minute cycles.
High voltage thermostats must be installed onto an electrical box.
The following guidelines are not necessary for floor heating applications:
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.

Procedure

Figure 1

Figure 2

1. Connect the power base wires to the power supply and load using solderless connectors for copper wires (figure 1).
2. For 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.
   
   This power base does not have a built-in ground protection device. Therefore, for floor heating applications, you must install a separate ground protection device at the main electrical panel. Contact your Aube authorized representative if you need a thermostat with built-in ground protection device.
3. If 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).
4. Push the excess length of the high-voltage wires back into the electrical box.
5. Secure the power base to the electrical box using the provided screws.
6. If necessary, set the configuration switches on the control module (refer to the control module user guide).
7. Install the control module onto the base.
8. Apply power to heating system.
