Aube Technologies TH150 Series Installation And User Manual

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
• TH150-1A2T
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
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.
Pass the wires through the center hole of the base and secure
the base to the wall or onto an electrical box.
Wire the thermostat. See section 2.2 for terminal designations
and section 3 for typical wiring diagrams.
Reinstall the thermostat onto its base and secure with the cap-
tive screw.
