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
Configuration and status display
• TH150-1A2T
• TH150-1F2T
Depending on the model, the TH150 thermostat can have up to
three outputs connected to the following control devices:
