stage of cooling with a fan. Auxiliary sensors may be added to measure
floor, outdoor or room temperature. Uponor Floor Sensor (A3040079) is
included to measure floor temperature to protect the floor from
overheating and enhance comfort. Programmable schedules support
either a 7-day or 24-hour schedule with two or four events per day.

Installation
Install the thermostat on an interior wall of the desired zone approximately 5 feet above the floor. Do not mount the thermostat on a location
that may be affected by localized heat sources or cold drafts. It may be necessary to install a draft barrier behind the thermostat to prevent
air from blowing through the wiring hole which can affect the thermostat’s built-in sensor. Refer to the Uponor SetPoint 521 Programmable
Thermostat with Floor Sensor Installation and Operation Manual for more information.
