3.7 Test actuators
Uponor Controller C-55/56 manages the temperature set point.
When a temperature change occurs, the actuator opens or
closes the valve to adjust the heat supply.
To test the actuators:
1 Press the button of the selected channel.
• The LED comes on, which means that the controller
receives a signal and powers the actuator on the
selected channel. The time for actuator opening is about
5 minutes.
• If the LED does not come on, then refer to the
troubleshooting section.
2 Press the test button twice to end the actuator test or wait
for 10 minutes for the system to end the test.
