• Page 2: Your new Comfort System T-32-P Universal Thermostat has been built using the highest quality components and design currently available. When properly installed and configured by your professional heating and air conditioning contractor, the T-32-P will provide years of trouble-free operation. The T-32-P has been designed to be an attractive, highly reliable and easy-to-use thermostat. By taking the time to read and understand this operation manual, you can take advantage of the many user features offered in this premium product. It is the responsibility of the user to ensure that this thermostat, or equipment connected to it, is operating to their respective specifications and in a safe manner. Due to ongoing product improvements, IO HVAC Controls reserves the right to change the specifications of the T-32-P thermostat without notice. The T-32-P can be used for both residential and commercial applications. The thermostat can be either programmable or non-programmable. This operation manual is broken into the following main sections: Residential Programmable Mode, Commercial Programmable Mode, Non-programmable Mode, and Common Functions. The T-32-P can be configured for a wide range of HVAC systems and applications requiring specific functions.
• Page 3: Residential programmable mode allows for various operation settings. Press the mode key to cycle through heat, cool, auto changeover, emergency heat, and off modes.
