TH150 400-150-000-C 5/9/06 1/6

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:

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. Installation

2.1 Mounting Instructions

n Remove 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.

o Pass the wires through the center hole of the base and secure

the base to the wall or onto an electrical box.

p Wire the thermostat. See section 2.2 for terminal designations

and section 3 for typical wiring diagrams.

q Reinstall the thermostat onto its base and secure with the cap-

tive screw.

2.2 Terminal Designations

The designations of the terminals vary according to the particular

model of thermostat. Refer to the following table for the description

of each terminal.

• TH150-1A • TH150-1F
