1111Uponor Control System - Operation Manual 11
4. System maintenance
Regular checks on your system components are
recommended in order to optimize performance. This system
requires no maintenance, but every few years the batteries
are to be changed.
Thermostat batteries:
The thermostats are powered by batteries. Discharged
batteries must be replaced. See: "5.2 Alarms", page: 11.
Controller:
The Power LED of the controller is always lit up. When it
blinks, this means that an alarm has been triggered.
Open the controller cover. The LED of the channel from which
the alarm originated is blinking rapidly. See: "5.2 Alarms",
page: 11.
Automatic exercise function:
The system is fitted with an automatic exercise function. Set
every 6 days +/- 24 hours, this function consists of a test-run
designed to prevent the pump and actuators from seizing up,
when they have not been activated since the last test.
5. Diagnosis and resolution
of alarms and faults
5.1 Normal system operating conditions:
5.1.1 Controller
The Power LED of the controller is lit up. All the channel LEDs
are off if there is no demand for heating or cooling. The LEDs
light up when the corresponding actuators are activated.
While on stand-by, waiting for the actuators to be activated,
the LEDs flash.
5.1.2 Thermostat Display T-75
The thermostat displays the room temperature.
5.1.3 Thermostat T-55 and Thermostat Public T-53
LED blinks one time only with each transmission.
5.2 Alarms
The errors are indicated on the controller when the power
LED blinks. The errors could be:
• Loss of radio transmission from a thermostat for more
than 3 hours.
• Low batteries on a thermostat.
• Short circuited actuator.
• Cover Alarm.
To contact your installer:
See installation report in the fold-out to find the contact
information of the installer.
Please prepare the following information before contacting an
installer:
• Installation report.
• Drawings of the underfloor heating system (if available).
You have the possibility of centralizing and
optimizing the management of the system by
connecting an interface to the controller. The
interface allows you to display and update easier
and faster the operating parameters of the system.
The interface also displays the causes of alarms and
facilitates diagnosis.
If your system is fitted with an interface, the
exercise function may be activated at any time.
STOP
Use a dry soft cloth to clean the Control System
and all it's components. Do not use any detergent.
WARNING
Note that some actions, e.g. actions involving 230V,
wiring, etc., are to be performed by a qualified
person.
If an interface is fitted to the system, alarms can be
readily displayed without the need to take the
controller apart. The interface displays clearly and
accurately the causes of the various alarms.
