Climatemaster CATP32U03 Digital Programmable Thermostat

Product Description

The CLIMATEMASTER CATP32U03 is a digital, programmable thermostat designed for residential and light commercial HVAC applications operating at 24 volts. It supports up to 3 stages of heating and 2 stages of cooling, making it well suited for multi-stage heat pump and conventional forced-air systems. The unit provides straightforward temperature scheduling through an easy-to-use interface, giving technicians and building owners reliable setpoint control. Licensed HVAC technicians typically install and commission this thermostat as a direct OEM replacement in ClimateMaster systems.

This thermostat is intended for use in HVAC systems requiring multi-stage control, including geothermal heat pump and forced-air equipment that call for a 24-volt low-voltage control circuit. Its 3-heat and 2-cool stage configuration covers the majority of residential multi-stage system layouts. The programmable scheduling function allows temperature setback and setup programming to match occupancy patterns, reducing unnecessary runtime without manual adjustment.
