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-15S series thermostat. When used on a TH13x-15S thermostat, this low-voltage power base must be connected to the line-voltage load using a solid-state relay (SSR). The PB130-024T is compatible with most solid-state 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

pInstallation 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).

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 and 4.2.

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.
