TH150 Series

Installation and User Guide

VAV Thermostat

1. Introduction

The TH150 Series electronic thermostat is designed for low-voltage pressure-dependent variable air volume (VAV) applications. It comes in four different models:

• TH150-1A	• TH150-1F
• TH150-1A2T	• TH150-1F2T

Depending on the model, the TH150 thermostat can have up to three outputs connected to the following control devices:

actuators

thermal valves (N.O. and N.C.) solenoid valves

solid-state relays (SSRs) silicon-controlled rectifiers (SCRs) mechanical relays

contactors

Accessories

RC840 or RC840T electromechanical relay

RT850 or RT850T solid-state relay

AC146-410 temperature sensor

AC144-03 temperature sensor

2.1 Mounting Instructions

nRemove the thermostat from its base by unscrewing the cap- tive screw and tilting the bottom of the thermostat up. The screw cannot be completely removed.

oPass the wires through the center hole of the base and secure the base to the wall or onto an electrical box.

pWire the thermostat. See section 2.2 for terminal designations and section 3 for typical wiring diagrams.

qReinstall the thermostat onto its base and secure with the cap- tive screw.
