Uponor Heat-only Thermostat with Touchscreen Installation and operation manual
Overview Installation overview The Uponor Heat-only Thermostat (A3100101) is designed for precise temperature control of hydronic radiant heating applications. The thermostat includes an option to add a floor sensor (A9010599) to measure floor temperature for enhanced comfort and to protect the surface from overheating. Prior to installing the Uponor thermostat, follow the instructions below.
Note: Avoid mounting the thermostat on a return-air chase or where the temperature inside the wall differs from the room temperature. If that is unavoidable, it may be necessary to plug or seal the wire hole opening to prevent the environment inside the wall from affecting the thermostat’s readings. Wiring Caution: Disconnect electrical power to the system to prevent electrical shock and damage. 1. Remove 3⁄16" of insulation from the wire ends. Ensure the wire ends are clean, dry and free from corrosion.
Heating modes This thermostat can operate a hydronic radiant system heating operation based on the air sensor measure operative temperature, a floor sensor, or a combination of both to provide the optimal level of comfort and control. • Air temperature only: When a floor sensor is not connected, the thermostat will maintain the room’s air temperature based on the desired temperature setting.
Change from off to heat mode Changing the temperature units As shown, when the thermostat is in OFF mode, the up and down arrows will not be displayed to remind the user that heating will not take place. F • To change from OFF to HEAT mode, press the OFF/HEAT mode power button in the lower left-hand corner of the screen. F FLOOR AIR • Once the rectangle appears around the AIR button, press the AIR button once more. The unit indicator will begin to flash.
Setting the maximum floor protection limit Depending on the installation or application, it may be necessary to limit how warm the floor gets to protect the wood flooring installed above the radiant system. When this temperature is reached, a warning will be displayed on the screen. To adjust the maximum floor set temperature allowed: F FLOOR TEMP LIMIT HEAT AIR FLOOR • Make sure the thermostat is turned on and in the HEAT mode and the SET indicator is not flashing. • Press the FLOOR button twice.
