Applications
This document describes the connections when the PB130-024T
power base is used on any TH13x series thermostat. This
low-voltage power base can be connected to a line-voltage load
using a relay or directly to a 24-volt device. The PB130-024T is
compatible with most relays; however, the following Aube relays are
optimized for use with this power base:
•
RT850 solid-state relay (SSR)
•
RT850T solid-state relay (SSR) with built-in 24-V transformer
•
RC840 electromechanical relay
•
RC840T electromechanical relay with built-in 24-V transformer
Supplied Parts
One (1) power base
Two (2) plastic anchors
Two (2) mounting screws
Installation Guidelines
For a new installation, choose a location about 1.5 m (5 ft.)
above the floor.
The thermostat must be installed on an inside wall facing the
heating system (except for floor heating systems).
Avoid locations where there are air drafts (top of staircase, air
outlet), dead air spots (behind a door), direct sunlight or
concealed chimney or stove pipes (except for floor heating
systems).
Installation Procedure
The installation must be carried out by an electrician and must
comply to local electrical codes.
Turn off power to the heating system at the main electrical panel
to avoid electrical shock.
Wire the base according to your application. See typical wiring
diagrams in sections 4.1 to 4.4.
For a floor heating system installation, con-
nect the floor sensor between the S and R ter-
minals.
Secure the base to the wall using the provided screws and wall
anchors.
Configure the switches located on the control module (if any).
Refer to the user guide.
Install the control module onto the base.
Apply power to the heating system.
Verify the installation by checking that the heating system can be
turned On or Off using the thermostat.
