Description
The Crandall THCR-4-CSS Two-Position Low Voltage Enthalpy Control is a pneumatic/low-voltage control device designed to monitor and actuate based on combined temperature and humidity (total heat) conditions. This enthalpy controller uses a SPDT switch to provide two-position control output, helping maintain desired environmental conditions in HVAC applications. Built to Crandall standards, it delivers repeatable transitions as conditions cross set thresholds, making it a reliable part of energy management and economizer strategies. Ideal for HVAC technicians and controls contractors, it supports efficient operation of ventilation and control systems.
