Installation Instructions

24-V Low-Voltage Power Base

nApplications

4.1Single SSR with Built-in Transformer

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

Red

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).

qInstallation Procedure

The installation must be carried out by an electrician and must comply to local electrical codes.

nTurn off power to the heating system at the main electrical panel to avoid electrical shock.

oWire the base according to your application. See typical wiring diagrams in sections 4.1 to 4.4.

p For a floor heating system installation, con- nect the floor sensor between the S and R ter- minals.

qSecure the base to the wall using the provided screws and wall anchors.

rConfigure the switches located on the control module (if any). Refer to the user guide.

sInstall the control module onto the base. t Apply power to the heating system.

uVerify the installation by checking that the heating system can be turned On or Off using the thermostat.
